3: OZONE, Site 1, Thu 09-May-1996 21:28:18 GMT, Ozone signals

• Index

 Below is an initial list of signals associated with
the ozone system. The ADAM, cosmos, will be setup to handle
16 analog channels.

name		voltage range	sample rate		description

O3teco		0 - 10 Vdc	     1 hz	TECO slow ozone (ppbv)
O3fs		0 - 5 vdc	    20 hz	fast ozone, FS,
O3ff		0 - 5 vdc	     1 hz	FS sample flow rate (slpm)
O3ft		0 - 10 vdc	     1 hz	FS reactor temperature (C)
O3fn		0 - 5 vdc	     1 hz	FS nitric oxide flow (sec)
O3fp		0 - 10 vdc	     1 hz	FS reactor pressure (mb)

  As soon as I have conversion formulas I will add them to logbook.
Present plan for channel assignments and gains/offset are:

channel #		gain/offset	signal
   0			  1 /  0	fast ozone
   1			  1 / -5	FS reactor temmperature
   2			  1 / -5	FS reactor pressure
   3			  1 /  0	FS sample flow rate
   4			  1 /  0	FS nitric oxide flow
   5			  1 / -5	TECO slow ozone

NOTE: the gain setting and offset for the fast ozone may change to 2 and -5
depending on the resolution needed.

• Index

Because we need to move the radiation stand further away from the
ETI / Campbell than what our cables are, Kurt discovered that for

Licor LI200SA:
A BNC extension having less than 75-ohms or so is OK, and 
that equates to a couple hundred feet of RG.

REBs Q7:
Additional cable of tens of meters is OK, provided the
WIRE INSULATION is NOT PVC

15: RAD, Site none, Sun 09-Jun-1996 14:42:00 GMT, PAM tower shadows

• Index

In order to place the radiation sensorsso that they would not be shaded
by the PAM mast, I determined the length of the shadow from curves that
John had prepared showing solar elevation vs azimuth for various dates.
I used the data for Aug 21 (longest shadows for locations north of the
PAM mast), latitude 40 deg N.

Length of shadow, r, for object of height h and solar elevation phi

r = h/atan(phi)

	azimuth	elevation	r/h
	------- ---------	---
	360	63 deg		0.51
	345/15	60		0.58

16: RAD, Site all, Sun 09-Jun-1996 14:58:25 GMT, Everest IRT footprint

• Index

The Everest infrared surface temperature sensors are located on the
crossarm at the top of the PAM mast.  The Everest is on the end of
the crossarm that points to the northwest.  It is pointed down at a
roughly 45 degree angle and looking to the northwest. 

I originally intended to point the IRT to the north as suggested by
Wilf Brutsaert.  However since the crop rows are oriented N/S or E/W,
it appeared preferable to look at the rows from an angle of 45 degrees
in order to not be biased by either the crop (looking normal to the
rows) or by the ground (looking parallel to the rows).

The field of view is 15 degrees.  Thus the footprint dimensions along
a line to the northwest of the station are from

	(10m)*tan(45-7.5) = 7.7m
to
	(10m)*tan(45+7.5) = 13m

The footprint dimension in the NE/SW direction is

	r*dtheta = h*tan(45)*(pi/180 deg)*(15 deg) = 2.6m

17: STATUS, Site 3, Mon 10-Jun-1996 22:15:12 GMT, EVE / DCOM332 Problems at Station 3

• Index

Yesterday, 6/9,96,
Kurt & I went to station 3 to finish some of the setup.
During the visit we were unable to talk to EVE with the Compaq.
It appeared that the Compaq wasn't transmitting to EVE so i cycled
power on EVE to observe the bootup sequence.  At first that went OK,
however because the Compaq still wasn't sending to EVE, i tried it
again.  On the second power cycle of EVE, it died with only the
boot message:	adding 3 symbols to the table.
given instead of the entire bootup sequence of EVE.

We brought the box back to the trailer and apparently 'fixed' the problem
by removing the DCOM 3V battery (which read 3.15V) and letting it 'flush'
the non-volatile.  We then were able to download a config file and run
'properly.'   The box was powered down overnight, powered up today to 
verify operation and then.

Today, 6/10/96, the box was installed back on the station.
At that point it was working, but when Kurt went into 'entersys' - 'goes' 
- 'self-test' it once again died.   The symptom was that all files in the
non-volatile got erased, including the config.dat.

Later, we went back to the station during a lull in the rain and i was
able to download a correct config from the Toshiba and restart normally.
HOWEVER, we decided to replace the VME power supply in hopes that is where 
the problem may be.   Upon power up, the boot sequence was wrong.  It turned
out that the config.dat was corrupted but only slightly.  i copied the
backup sta003.dat to config and restarted: that worked.

Conclusion: DCOM332 has problems or much less likely the software.  We'll 
buy some new 3V batteries and replace the existing ones in hopes that'll help
the problem.

• Index

The prop-vane wind direction at station #3 looked incorrect, so
John checked the boom direction parameter on the prop-vane and
found it to be equal to zero.  John entered the correct value,
138.5 degrees.  John recall entering a nominal value of 135.0
when he and Kurt aligned the prop-vane to the boom, so it is 
likely that the prop has also forgotten this alignment value of
the optical encoder.

• Index

The BPH s/n #40 was installed on the station and the earlier problem
was fixed.
The problem was 2-fold:
	- ATI A/D connector's power ground pin was pushed up (and was
	  a bitch to get down without the proper tool).
	- The Limo connector on the BPH housing appears to also to be
	  making poor contact.  A little bit of reseating and wiggling
	  seemed to do it.

I cannot say for sure whether or not the BPH will stay up.  The readings
when we left were consistent with the TRH, but not exact: about 5% higher
in RH.

39: RAD, Site 3, Fri 14-Jun-1996 22:29:24 GMT, Tsfc at #3 is still down, EVE A/D is OK

• Index

Because the malcontent Tsfc seemed to work for awhile on station 1 this
morning, Kurt put it back on 3 later on, however, it was still showing
bad values.

We diagnosed the EVE A/D using a 1.3V battery on a 16-pin amp connector
for the tsfc pins, and swapped the battery box output to the AD1 port,
plus tried the Tsfc on channel 0 (AD0 port).  The EVE AD channel 4 is OK
with both the batt, and power box inputs as determined by the EVE ad
monitoring routine.  The Tsfc sensor was still bad, and appeared to be
having stray capacitance that was charging/discharging. 

We'll need to try to isolate this problem tomorrow on station 1 by
lowering the mast and trying to determine whether its the cable of the

• Index

I loaded the 'June 12th' version of Burghart's
pam2netCDF translator program.
The old version was renamed to ".old"
The new version allows fields to be generated for even if there is no data.

41: PROP, Site 3, Sat 15-Jun-1996 15:00:39 GMT, Prop-vane alignment

• Index

The wind direction at site 3 for the period 0000-1400 GMT, June 15,
matches the wind direction at site 2 very well.  This suggests that 
the boom alignment parameter in the prop-vane is okay.

Thus we will not make a special site visit to check the boom alignment
at site 3, but we will check it next time we lower the mast at that
site.

42: SONIC, Site 3, Sat 15-Jun-1996 17:38:47 GMT, Adjusted sonic "u" axis

• Index

The u axis on the ATI was bad on the mornings of June 14 and 15.  The
signal appeared to improve significantly around sunrise, suggesting a
temperature or humidity problem.

I visited the site between about 1130 and 1230 CDT.  The electronics
enclosure was dry inside.  Looking at the received signals with the
'scope, it was evident that the u axis was noisier than v and w.  I
tried loosening and retightening the transducers on the u axis, but
this had no effect.  I swapped the u and w receive boards and the noise
followed the board.  I replaced the the u and w boards in their proper
slots and reduced the amplitude on the u receive board about 1 full
turn of the pot.  This made the signal look a lot cleaner.  I also
reduced the amplitude on v a little, so that all 3 boards have the
first negative wave at an amplitude of about 4-5 V.

I could not rezero the u (or v) axis, because I did not have a
field terminal to determine the temperature and humidity.  However,
I suspect that my adjustment made little change in the zero.  We will
rezero on a subsequent visit.

45: SOIL, Site none, Sun 16-Jun-1996 15:25:01 GMT, Soil Moisture Measurement: Temperature Dependence

• Index

Campbell Soil Moisture Probes
all appear to have a significant temperature dependence that
causes about a 3-5% diurnal change when the soil temperature
varies about 10-20 degrees.

I don't know the specifics of the sensor enough to say whether
this is a real problem or not (need to R.T.F.M.!), but that does
appear to be the case.
....
YES, the Campbell manual does include a reference and a description
of a temperature correction equation.  That has not been put into 
the Campbell software program, or in EVE yet.

Between 96/06/15 ~18Z through 96/06/16 16:40Z.
The Tsfc sensor at station 1 was swapped with the 'bad' sensor from station 3.
This was done to determine whether the sensor from 3 or else the electronic box
there was causing the erroneous values.
It appears that the sensor is OK.
It was mounted overnight on station 1 on the lower cross-arm, pointing SE past
the TRH.

Site 1

6/20/96  

The station is nominally located 1/4 mile east of the center of Section
2, T18N, R7E; 1/2 mile south of road 1200N and 1/4 mile west of road
500E.  The station is located on the north edge of a cornfield that
extends roughly 1/4 mile to the east, south, and west.  The field to 
the north of the station is also corn, but is broken up by N/S strips 
of grass extending south about 1/4 mile from the vicinity of the 
Bondville FAO driveway.

The corn to the south of the station is planted in E/W rows with a
spacing of 30 inches and is currently (6/20/96) about 60 cm high.  The
corn in the immediate vicinity of and north of the station is also in
E/W rows, but is currently only 40 cm high.

6/22/96:  Corn to south of station is 30" (76 cm) high.  To the north
of the station it is 18" (45 cm) high.

6/25/96: I measured the corn height on 6/25/96 to the Southwest of station 1.

Site 2

6/18/96  

The station is located in the nominal center of the NW 1/4 of Section
26, T18N, R7E; 1/4 mile south of road 800N and 1/4 mile east of road
400E.  This 1/4 section is planted in corn.

The corn is planted in rows with a spacing of 30 inches.  To the SW,
SE, and NW of the station, the rows are oriented E/W, but to the NE of
the station the rows are oriented N/S.  However, all the rows in the
immediate vicinity of the station are oriented N/S.  

The corn is nominally about 0.75 m high, but some is as high as 0.9 m.
There is a good stand of corn under the radiation stand and in the
vicinity of the soil sensors, but the Everest is looking at a low wet
area that has a weak stand of scattered corn about 0.5 m tall.

Site 3

6/16/96  

The station is located in the nominal center of the SW 1/4 of Section
26, T18N, R7E; 1/4 mile north of road 700N and 1/4 mile east of road
400E.  This 1/4 section should eventually be planted in soybeans.

Field to north of station (1/4 mile to N, to E, and to W) is planted in
soybeans, currently 2-5 cm high.  The beans are planted in rows
oriented predominantly E/W (except for N/S end-rows at the east(?) and
west ends of the field); the rows appear to have a spacing of 7.5 in.

The field to the south of the station (1/4 mile to S, to E, and to W)
is currently unplanted.  It has standing corn stubble from last year's
crop.

The station is located on the southern edge of the planted section.

6/22/96:  The field to the south of the station was recently planted.
The beans to the north of the station are 4" (10 cm) high.

6/24/96:  The beans to the south are beginning to emerge from the

Visited station #3 on June 16, between 1400 and 1500 CDT.

Measured sonic height to be 3.21 m

Looked at signals with scopemeter and saw intermittent noise preceding
received pulse on the u axis.  Tried to adjust the capacitor to reduce 
noise, but this only made it worse.  On my previous visit it was 
apparent that this is a problem with the board, and the daily plots
suggested a temperature-dependent problem.

52: STATUS, Site 3, Mon 17-Jun-1996 14:38:00 GMT, Replaced Everest, checked prop alignment, painted rad stand

• Index

Visit to station #3 on the afternoon of June 16, about 1400-1500 CDT.

Lowered the mast in order to replace the Everest on the 10m crossarm
(pointing down to the NW at 45 degrees).  John found a blown fuse
in the line providing power to the Everest, so this was part of the
problem.  The fuse will be replaced, hopefully today.

Temporarily disconnected the bandpass hygrometer because the cable
interferred with lowering the mast.  Reconnected it to eliminate the
interference.

While the mast was lowered we checked the alignment of the prop-vane
by holding it paralled to the crossarm and looking at the output.  It
appears to be correct.

See a separate entry regarding work on the sonic anemometer.

John touched up the radiation stand with black paint.

• Index

Sonic at station 3 continues to have spiking at the 1% level on

spiking on the v axis and spiking on the w axis.

The sonics at stations 1 and 2 appear to be operating okay.

58: BPH, Site 3, Tue 18-Jun-1996 15:47:33 GMT, Bandpass hygrometer errors

bph at station 3 reporting bad data during the daytime, June 17.
This sensor already appears to be more sensitive to radiative
heating than stations 1 and 2, but from 1500-2100 gmt, June 17,
the temperature was about 10 degC too high.  From 1400-1600, the
RH was 90-100%, while the other sensors reported 70-80%.

bph at station 1 has a tendency to saturate around 98% RH at night.
This occured on the nights of June 16 and 17.

59: SONIC, Site 3, Tue 18-Jun-1996 22:02:31 GMT, Replaced u axis receive card on sonic

• Index

ATI shipped a new Receive amplifier board for the sonic at site 3.
I visited the station to replace the board around 20:30 - 21:00 gmt.

Before replacing the board, I looked again at the signals with the
scopemeter and confirmed that the noise followed the board when I
interchanged the u and v boards.  Then I swapped the boards back and
replaced the u axis board with the new board from ATI.  The signals
look a lot better with the new board.  After running with the new board
overnight, I will send the old board back to ATI for inspection and
(hopefully) repair.

I zeroed the u axis after confirming with the scopemeter that the
signals had the proper amplitude (first positive wave < 0.5V, next
positive wave ~13V).  The zero is probably only good to no better than
0.5 m/s since the wind was blowing parallel to the u axis and the
zero-wind tube is pretty leaky.  After zeroing, I looked with the
Toshiba at the sonic output and it was on the order of 0.5 m/s and
fluctuating by several tenths of a m/s.  Will need to rezero when the
wind is lighter.

I dried up a little water in the bottom of the electronics box and
resealed the edges of the door with electrical tape.  The hole appears
to be limiting the water depth as intended.

Check Corn height:	23" (top of knee)

Uploaded METPPF Data:

Barometer Fixed:	Power cycle required

ETI Test:
The ETI's are under-reporting rain.
I performed some tests to determine whether this is caused within the ETI, or
else the Campbell Logger:
- Conditions: Warm, West wind ~4-7m/s
- Electrical: OK
	ETI is wired correctly and Campbell P1 port is being held at 4.8V.
- Initial Test:
	Poured '44-tip' water in quickly (~10 seconds)
	heard multiple sets of 5-pulse beeps each second and saw the
	'tipping' on the CR10 using a digital meter observing about 15 'cycles'
	NOTE: that with this meter i could not tell whether or not the pulses
	were actually pulling the P1 port to zero.
	Via EVE, logger reported 10 tips.
	Waited approximately 5 minutes...no more pulses.
- Power Cycled Box while doing other tests/baro/etc.
- Second Test:
	I decided to rerun the test and try to count the 'tips' exactly because
	i may have missed a few on the first go around because the beeps and
	meter 'pulses' didn't coincide exactly and i lost count a bit.
	By my watch....
	17:53:10-20 poured in '44-tipper'
	17:54:28   14 beeps/pulses
	17:55:28    3 beeps..
	17:56:	    nothing
	17:57:28    1 beep..
	17:58       nothing
	17:59       nothing
	EVE Check:  11 tips, not 18
- Third Test:
	simply because....
	18:01:15    poured small remaining amount of water in
	18:02:28    6 beeps/etc.
	18:03:28    4 beeps/5 pulses....odd, but...
	18:04:	    nothing more
	EVE Check:  6 tips, not 10
- Conclusion:
	- I need to re-do the tests using a scope to count exactly, and the ETI
	test software to examine what the processor says (didn't have the right
	cable today).
	- I believe the ETI itself is under-reporting and skipping the second
	and third minute pulses.
	- The Campbell may be missing tips, but cannot tell without seeing
	exact wave-form to determine whether the line gets pulled exactly to
	zero or not.

62: GOES / RF, Site none, Wed 19-Jun-1996 15:43:55 GMT, FreeWave Radio Interference with Profiler

• Index

Wayne Angevine noticed interference on the 915 UHF profiler
from the Freewave radios.  This amounted to raising his noise
floor from about 12db to as much as 24.

A series of tests were performed to try to reduce or eliminate
the problem.
	- Reduced signal power to about 5 then 3: no luck,
	still had interference, but that was where i lost comms.
	- Lowered the antenna.  It had probably been 'seeing'
	the profiler.  This helped, but not enough.
	- Rotated the lowered antenna and put power level at 4.
	This produced the best results, reducing the noise floor
	to 13-15, except for one axis: west, which remained up 
	at about 18 (possibly from atmospheric reflects, the
	antenna was shooting to the west of the profiler, or else
	reflection from a nearby Rohn tower).

Results:
	- The interference is configuration dependent.  Some attempts 
	improved one of the beams, but degraded others.   There's no
	doubt interaction with the distance, pointing angle and surrounding
	structures.

	- No configuration is acceptable to Wayne with the old
	Freewave radios.
	this is because he already has marginal signal levels, esp.
	at the middle height range gates.  

	- Wayne may be willing to allow us to have comms, except
	Between the hours:	9am - 5pm local.
	Those are his peak periods of interest.


New Radios Test:
	The new models of Freewave radios scan from 921-928.
	These are the ones we plan to use for aster.

	No Problem with these!
	We tried running the new radios in the 'worst' configuration
	from before (full power, raised yaggi pointing over the profiler)
	and Wayne didn't see any interference.

73: SONIC, Site 3, Fri 21-Jun-1996 20:49:08 GMT, Swapped u and w receive boards on ATI

• Index

The flags plot for site 3 has shown spiking at the 1% level on the w
axis, particularly during the daytime, and the zero level appears to be
wrong on the u axis.  Between about 1200-1300 CST on June 20, I swapped
the u and w receive boards to isolate the cause of the problem.
However, I could not see any problems on the scopemeter with either
signal.  I adjusted the levels of the signals (not much adjustment
required) and then we zeroed these two channels.

Looking at the current plots for June 20-21, it is obvious that this
change eliminated almost all of the flags on the w axis, but now there
are continuous flags (both night and day) on the u axis at about the 
0.3% level.  The rezeroing has fixed the offset problem on the u axis.

The Zimmermans will ship the refurbished Receive board back to us
today, but Gary could not find much wrong with it.  I will try
replacing the bad w board with the refurbished board.  Meanwhile I will
leave the new board in the w channel and the old w board in the u
channel.

• Index

The bandpass hygrometer temperature at site 3 appears to be about 1
degC too high during the day, as though it had a radiation heating 
problem.  Steve suggests checking the whether the inner shield is
properly recessed (about 1 inch) relative to the outer shield or
whether the prt is touching the gaurd.  The temperatures at sites
1 and 2 appear to have the expected diurnal cycle relative to the
hygrothermometers which are at 2m compared to (3.2, 4.5, 3.2)m for
the bandpass hygrometers.

We also think that we have the wrong coefficients loaded for the
bandpass RH calibrations at all three sites.

83: SONIC, Site 3, Sat 22-Jun-1996 22:24:12 GMT, Looked at sonic at site 3

• Index

I visited site 3 to look at the sonic signals.  They look fine on the
oscilloscope, but I hoped to detect enough errors looking at the flags
in order to perhaps readjust the sonic.  However the number of flags 
was on the order of 0.1%, so no luck.

Gary Zimmerman has suggested that we may have the gain too high on
the Receive boards so that the "true" first wave is at 10V rather 
than 0.5V.  I tried reducing the gain all the way, but this did not
reduce my "second" pulse below 1 V.  I returned the gain to the 
previous setting, but did not rezero the sonic.

I noted in the dailyplots that this sonic was very different from sites
1 and 2 yesterday:  u:u, w:w and u* were all lower at this site, but
sigma_w/u* looks about right.  Also tc:tc and w:tc were higher than at
the other sites and w:rh20 was also lower.  This was the one of the few
times that the wind was blowing from the field to the south with no
growth, so perhaps this was the cause.  Also, this field was recently
planted, so this also may have changed its albedo, etc.  Looking at
the data from today, it is quite obvious that this site is different
when the wind has a southerly component and a fetch with no vegetation, 
but matches the other sites when the wind has a northerly component 
and has a fetch over the growing soybeans.

Uploaded Data: JD172,173

New Config Attempt:
I tried to install a new config that included a new MESG format for ATI
by having a CREATE of ATI.[u,v,w,ts]rate for percentage of spiking as
determined by the respective spike counts divided by the ATI.cnt
value, but the 'divide' option complained about the '.cnt' value even
though it exists.  I ended up putting in a revised config that simply
includes a printout of the ATI.cnt.
Otherwise the coefficients for the config are the same as the ones put
in yesterday.

89: SOFTWARE, Site none, Sun 23-Jun-1996 17:25:29 GMT, Time in Splus dailyplots

• Index

Gordon has revised the method for inputing time to the dailyplot
routines, enabling an arbitrary starting time and length.  The new
method for passing time to the routines is via the function dpar(),
which is like par():

Prior to making the first dailyplot within an S session you must 
execute dpar, e.g.

dpar(year=1996, mon=6, day=15, hour=12, lenhr=24)

Then fun.xxxx.plot will produce a 24 hour plot beginning at 12:00 gmt on
June 15.  Subsequently dpar(day=20) will produce the same plot for June
20 or dpar(lenhr=96) will produce a plot of 4 days of data.

dpar.next() and dpar.prev() will increment dpar()$hour by + or -
dpar()$lenhr.  

dpar.now() gives a plot ending at the present time and is also a handy
way to initialize dpar at the beginning of a session.  dpar.now() is
currently executed by $ASTER/.Data/.First()

Try dplot() to get a graphical interface to the dailyplots in the
daily_S_plots script.  Provide comments and feedback to Gordon.

I was again unable to communicate with the Campbell to download its program so
that it can be modified for the proper totalizing method for the ETI.

92: RAIN, Site 2, Sun 23-Jun-1996 19:23:03 GMT, ETI Always drops Cal. Coef. on Power Cycles

• Index

ETI Check performed during station visit (see previous note).

Jerry Price said the ETI shouldn't lose it's coefficients unless the
battery voltage goes down slowly.  Also, he wanted to see a higher voltage than
11.2, which i saw at station 1.

Voltage at Campbell and ETI: 13.3
Coefficients were definitely gone.  Programmed them in.  Cycled power by pulling
the 9-pin cable.  Coef. dumped.  Reconnected the ETI to the input power rather
than on the campbell take-off lugs.  Programmed Coef. Cycled power. Same
results.   Repeated by programming coef., cycling power using the main EVE box 
switch, same results.

Conclusion, the ETI will dump it's cal coefficients on a power cycle.
ETI probably needs to put a delay into the decision about reprogramming the
coefficients during 'low-voltage' situations.

93: SOIL, Site 1, Sun 23-Jun-1996 21:10:30 GMT, Buried soil temperature cable.

• Index

The soil temperature plots show that station 1 is noticeably warmer
than stations 2 and 3.  When I installed this particular sensor, I
recall that the wire near the sensor was very close to the surface.
I visited the site around 1400 CST and found that a short length of
cable near the sensor was actually on the surface.  I tried to push 
the sensor a little deeper and reburied the cable.

94: BARO, Site 1, Mon 24-Jun-1996 15:29:39 GMT, Barometer stopped yesterday

• Index

The barometer at station 1 stopped yesterday around 1430 CST, 
presumably because of AC power failures that we also experienced
around that time at the PAM base.

95: SONIC, Site 3, Mon 24-Jun-1996 19:39:28 GMT, Replaced refurbished "u" Receive board

• Index

ATI sent back the "u" board from station 3 that I asked them to
repair.  Gary Zimmerman said that he could not reproduce the problem
that I saw in the field.  However, he did "change a couple of things
that might be a problem."

I replaced the "w" board, which had been operating in the "u" channel,
with the refurbished board.  I could not see any problem in the signal
with the oscilloscope, either before or after the swap.  However, I
did monitor the sonic spikes in the field.  

Before the swap, with a leaky zero-wind tube on the u axis:

sample count = 2900, u spikes = 7, v spikes = 0, w spikes = 18
sample count = 2953, u spikes = 4, v spikes = 0, w spikes = 28

Replaced refurbished u card in u channel: 

sample count = 2997, u spikes = 0, v spikes = 0, w spikes = 6
sample count = 2970, u spikes = 1, v spikes = 0, w spikes = 10

John also changed the charge controller in the battery box:

sample count = 2945, u spikes = 0, v spikes = 0, w spikes = 14
sample count = 2991, u spikes = 1, v spikes = 0, w spikes = 4

This suggest better performance with the refurbished board, but no
dependence on the battery charge controller.  Note that I have left the
new ATI board in the w channel.

I tried to rezero the u axis, but the wind was blowing moderately 
from the west, so the zero is probably not too accurate.

96: BPH, Site 3, Mon 24-Jun-1996 19:55:35 GMT, Swapped bandpass hygrometers at stations 1 and 3

• Index

John is swapping the bandpass hygrometers at stations 1 and 3 today,
in order to isolate the problem with the bph at station 3.  He removed
the bph at station 1 (#23) and we mounted it at station 3, entering
the appropriate calibration coefficients in EVE.  

At that time we found the inner shield of the hygrothermometer
extending about 1.5" below the beehive.  John replaced it, but found
that one or more of the screws that hold it in place had stripped their
threads in the Delrin outer cylinder.

John disassembled the bph from station 3 (#40) and looked at the
sensing elements of the 50Y, but there was no apparent problem.

John will install #40 on station 1 later this afternoon.

BPH #40 Installed
This was the turkey from station 3.
Still looks out...approx 1.8 deg higher than trh mounted at 2m.
Correct coef. were loaded earlier today; confirmed that.


Batt. Box  Installed
Put in the box taken from station 3 today, but with a Deka gel.
Noticed the VBATT MONITOR dropping out on eve, but not on the
charge board distribution connector....probably LOOSE WIRE ACCOUNTS
FOR THE SAW-TOOTH we've seen with this box.


ADAM DC Power Problem:
While getting ready to put on the batt. box, i monitored the DC from the
ADAM.  As before it was hanging around 11.15, however, i noticed a glitch or
two dropping as low as 10.5 or so.
Tried to tweak DC supply adjustment pot in ADAM power dist. box.  It was
way sensative, and i saw lots more 'jumping around'.  This happened even
after totally disconnecting from everything else.
Ended up discecting the dist. box to get at the stuff. At one point, the supply
'died' while trying to adjust the pot.  Finally seemed to get the
DC supply going and stabilized at 14.  Plugged it into the batt box solar in.
There it seems to be holding the battery at 13, fully 'PAM' loaded
for the moment at least.  I may need to adjust the supply again tomorrow when
the battery has filled up.   This is probably too high for it.
APPEARS as though the DC SUPPLY is a bit flakey in this ADAM, or has a
loose connection on the board.  PROBABLY SHOULD BE REPLACED, OR THOROUGHLY
CHECKED out.


ETI Coef. Drop Problem
here at least may be explained by the power glitching on the ADAM.
However, i've seen the same symptom at station 2 (solar).
Didn't have a chance to 'scope' the ETI input power signal on powerup to look 
for that possible cause of the reset....tomorrow maybe.


[to avoid rutting the field and lug battery out, got to ride the UI's
4-wheel ATV....yeeehaaah!]

• Index

Station 3 Visit: 16:15-18:00Z, 96/06/24, JD176

Monitored Power System:
There was noise coming in from the battery box.  It was about 300mV peak-to-peak
at about 300hz.  This was from the Prostar PWM charging characteristics of
pulsing the battery.  I don't know if this noise is causing any problems with
the ATI, or ETI, or elsewhere.  The actual battery level was about 12.8

Swapped BPH:  s/n#40 out, s/n#23 in
new coefficients installed using config: sta003a.dat

Swapped VME power supply
High efficiency unit installed.

Swapped Battery Boxes
Put in the Flexcharge unit.
Removed the Prostar unit.  It was the prostar box that was showing the sawtooth
on the battery voltage monitor via EVE.
Monitor of Power system w/Flexcharge:
It also uses PWM, and that appeared to be about 600mV at 1-second long pulses
(at maybe .25 Hz).  The amplitude varied considerably with the sunshine vs
cloudy charge levels.  Again, i don't know if this noise will effect any of the
systems: unlikely.

TRH Problem:
Noticed that the inner metal tube of the shield had dropped down by about 1.5"
Tom has logged this elsewhere also.  2/3 of the nylon set screws holding the
shield in place have stripped.  A better mechanical design is needed.

• Index

Measure and record the crop heights at each station on a regular
basis.  Most stations are at intersections of different plantings, so
the crop height will be different in different directions.  These are
recorded in a logbook entry dated June 17.  Station photos should be made
on perhaps a weekly or bi-weekly basis to record the changes in the
crops.  Take some regular photos also of the crop under the net
radiometer, over the soil sensors, and under the Everest.

Don't trample the crops under the net radiometer, over the soil sensors
or under the Everest IRT.  The Everest footprint extends along a line
to the NW of the station and between 7m and 13 m from the station.  The
footprint width (in the SW/NE direction) is about 3m.

Keep the sonics at a height between 3 and 4 meters above the top of the
crop canopy to the SW of the station.  Don't forget to relevel the
sonic after you move it.  The sonic height (above the ground) can be
determined by measuring along the lowered mast to the hinge point and
then measuring from the hinge point to the surface.  The sonic heights
are recorded in a logbook entry dated June 25.

There are no filters on the bandpass hygrometer 50Ys.  Steve Semmer will
determine a maintenance procedure for cleaning these.

Take soil samples and make gravimetric soil moisture measurements as
often as possible.

ETI Checks today:

Jerry Price could reproduce the dropped coef. only by 'sparking' the
input power, these tests were to check out the possibility of 'dirty'
power causing our problem.

Station 3, s/n51
----------------
When i arrived and checked the eeprom cal coefficients, they were OK.
This station has definitely been power cycled since they were loaded.


Station 1, s/n57
----------------
This is the A/C powered station.  The power system was stabilized yesterday
with the addition of a battery box, in between the DC supply and PAM.
The voltage is around 12.5-13 and is rock (granite, not pumice that is) solid. 

Coef. were dumped when i arrived.
Programmed them in, and cycled power hoping that they'd stay programmed..
....foolish me. 
Test for unusual power up glitching.
The scopemeter was setup to trigger/record the positive slope.  Coef. were 
loaded and verified and power was cycled.  The waveform rose from 0 to 
10V within 250microSec, 12 within 600microSec, and stabilized at 12.5 within
1.2mS: no glitches, signal was very clean.  The Coefficients however, suffered
greatly.
Test for unusual power down glitching.
After confirming the power up looks good, i decided to look at the power down.
It dropped from 12.5 to 4 within 200microSec.  It did take
3mS to drop from 4 to 2Volts, and the scope memory trace didn't have enough
to show the wave all the way to 0, but it was a very clean signal.  However,
the reprogrammed coefficients suffered greatly.

I tried these tests both with and without the PC attached.
It may well be that ETI s/n #57 and #58 are the only ones having this problem,
because #51 did retain it's coefficients after i programmed them in several
days ago.

Jerry Price had recommended to put a small 12V battery in the gauges just to
keep them up until returning to Boulder.  We may do that because frankly this
isn't important enough for this project to continue right now.

Beginning 96/06/25, 14-local, 19Z (exactly the moment when Tom left for the
airport!) the v-component at station 3 began glitching well above 1%, and
as much as 10%.

I visited the station later in the day, about 21Z, but didn't look at the

climbed on the tower, but didn't notice anything unusual at the time.

I'll check the site this morning....

Occasionally we have seen some 'sawtoothing' on the TSFC sensor at station 1.
Also, at Station 3, we saw much 'sawtoothing' on the power monitoring system
until the battery charging box was swapped out.  Two days ago, the 'offending'
box was put online as a UPS buffer for the a/c power system on station 1.
Unfortunately, it's Vbatt data immediately went into a big oscillation between
0-16V.  So in order to chase that problem....

Station 1 Visit: 22:05-23:35Z, 96/06/25, JD177

Power Monitor System:
The Vbatt reported by EVE from this charge controller box has
been bad, previously at station 3, now here at 1.
The actual battery voltage and the divider output are rock solid.
The EVE a/d system monitoring capability was rock solid.
The config for vbatt was correct.
Nevertheless, EVE message reports jump all over the place from 0.08 to
16, and back, etc.
Jumpering to make sure the ground connections didn't help.
The vbatt monitor voltage is around 2.3V (also shown by eve a/d) so
appears to be consistent with a 5/1 voltage divider so the resistors are
probably OK.
It almost looks like we're getting a wrap around on the A/D softw. count for
some reason...will need to pursue this later after looking at some
documentation/etc. 


Conversation with Matt:
It now appears that the problem at this site is probably the CPU board he
sent out when the other one died.  He indicated that this one has a PAL problem
in switching a/d channels.  That's consistent with the 'residual/wrap-around'
problem mentioned.  Why it's effecting channel 0 (vbatt) and seemingly not
the others.....
Therefore: to prevent problems with TSFC and hopefully remove any more episodes
of sawtoothing on it, i'll comment out the A/D channels 0-3 sometime today.
We should look at the 'sawtoothing' on the TSFC to see if it's been
temperature related.

U Component zeroed.

V Component
Everything appeared OK upon arrival, both inside the electronics box and on the
sonic head assy.
EVE at the time was only showing 1-2 spikes on V.
I went ahead and zeroed u, then put the chamber on V.  For the most part the 
spikes were few and far between, but once i saw a burst of 35.

Signal quality on scope meter appeared OK, but i wonder if it's being
overdriven although i'm not sure.  The initial rize not only was less than 1v
but it was probably .1v on both the V and W, perhaps .3-.4 on U.
During this period i saw spike counts on W that actually were greater than on 
the V

Ground: i tried to re-establish the ground for the electronics box and found it was about .4ohms.  I also reseated the U,V,W boards and cycled power on the box.

The glitches for the most part over an extended period appeared to be
distributed among the 3 components, mostly on V/W with W possibly being worse.
So I decided not to swap the V/W boards, however, looking at the plots
this morning (Thurs, 6/27) the V spikes are by far worse, even though there
was some terrible spiking on W from about 17Z-0Z (ie when i was there).
I now wish i'd replaced and re-adjusted the 2 boards and will probably do that 
today.

The Soldn was rewired in at about 19:40Z, 96/06/26

I was unable to repair the RG58 BNC, so instead i moved the millivolt adaptor
to the sawhorse and soldered an extension from it to the Campbell.  the new
cable is about 50' long perhaps, so it'll be interesting to see if it effects
the voltage measurement.  It probably should be changed back at some point
because i only taped the mV adaptor and soldered wires as a water seal.

119: EVE, Site 1, Thu 27-Jun-1996 00:09:14 GMT, Squirrely config for batt. monitor / checkout

• Index

To test the hypothesis that the CPU here has an A/D switching problem in its
PAL, and to minimize any potential effects on the Tsfc sensor, which has had
some minor 'sawtoothing' as well, I slapped together on site in the Compaq, a
modified EVE sta001.dat configuration that removed the sampling of AD1,2,3
but retained Tsfc on 4 and Vbatt on 0.

This config still sends the proper number of message bytes (confirmed that)
but for the 6 'power value' slots sends
	Vbatt: avg, avg, avg, min, max, max
instead of:
	Vbatt-avg, icharge-avg, iload-avg, tbatt-avg, vbatt-max, icharge-max


I looked at the zeb plots this morning and it looks very odd.
After i left the station last night, the 
vbatt was indeed sawtoothing but rapidly that damped out and 
it looks pretty stable since about 3,Z.  Interestingly, the
tsfc there also appeared to slightly sawtooth immediately after i left, but
within an hour or so, just when the vbatt began to damp out and settle down,
the TSFC quit having oscillations.  Granted it was late in the day and the
sun was low in the sky, but the entire day had quite clear skies and no clouds.

Will need to continue to monitor this.  It does appear that there may be some
very small oscillations in the TSFC data at 3 as well, but that could be my
imagination given the situation at 1.

Station 3 Visit: 17:05-20:55Z, 96/06/27, JD179

This ATI has been having fits since the beginning.  In particular the V
is continuing to spike and the W did yesterday when i was there as well.
Today, I came out to look at the signals and swap the currently worst board (V)
with the currently best board (U).

3 Changes:
	- Replaced the V Transducers
	- Swapped the "V" and "U" boards
	- Adjusted and zeroed all of the signals

I believe the situation is better now, primarily from the adjustments that
were made, however, the "V" board was still showing a few spikes when i left.
Meanwhile, i'm trying to examine the data to determine whether things have
improved according to the data.
By adjusting/damping the signals down in the 3 axis, i hope that the
spiking will clean itself up.  I definitely noticed 'jumping' in the
signals on the 1st peak that supposed to be below .5V, but after i made the
pot adjustments i didn't see very much of that. (except on the "V" board,
but those all seemed to remain below the .5V level at least).

Note: Zero Chamber now in use does let in a bit of wind so some of the
'signal glitches' i observed may have been related to that.  The winds
varied during the visit from about 5-6ms to calm.

I continuously monitored EVE for spike flags and the Fluke Scopemeter.  This
is what i saw/did:


	Sample	     Spike Accum.	
~Time	Cnt	U   V   W	Comments
12:12	1373	    1		Things appear roughly normal even though i know
				lots of spiking is going on.
12:14	2880	1   1		Saw some noise on the v board even with
			 	the zero chamber.  also some waveform that
				could have been some wind.  The 1st peak was
				seeming to jump as high as .8-1V
12:30				Reseated V transducers.
				Still seeing lots of glitching on V
12:35				Replaced Transducers with spare
				Still seeing glitching on V
12:39	730	   131		Yuk.
12:40				Swapped boards "V" board is now on 'U' slot
				and the "U" board is now in the 'V' position.

12:47	1138	5   5
12:49	2373	13  5		Noise may be better than before but still
				see a few pulses before 1st peak and it's
				still occassionally over 1V...too
				much. zero looks close.
12:52	910	7		Begin adjusting pot counter clockwise to
				damp the signal a bit.
12:58	1853	3
12:59	2783	4		Signal looks better, maybe a few burps to
				.4-.5 V on the 1st peak.  Tweaking pot a
				bit more.
13:01	900	0   0   0
13:03	1933	3   0   0	First peak is barely perceptible and not
				going above .5V.   The 2nd peak is no
				longer saturating, but is hanging around
				11V more like what the manual indicates.
13:05				Zeroing "V" board in 'U' slot: 30-deg 34%RH
13:11	924	0   0   0	Monitoring "U" board in 'V' slot: signal

				is just saturating at 12, the 1st peak is
				hanging around .3, but occassionally burps
				to .5
13:13	2151	0   0   0	Adjust pot CCW a bit. 2nd peak now hanging
				in about 10-12 but not saturating.  1st is
				stable at .1-.3

				1st peak is .3-.7, 2nd is saturating.
				Adjusting pot CCW to get 1st peak to
				.1-.35, 2nd peak 10-12V now.  Otherwise
				this board looks pretty clean even though
				we've had spiking the last few days.
13:30				Zeroing "W": 30-deg 34%RH, relatively calm now.
13:38	1530	0   0   0	Need to Rezero "V" board in 'U' slot

13:50	2130	0   0   0

124: SONIC, Site 3, Fri 28-Jun-1996 14:02:32 GMT, "V" board now in 'U' slot still bad

• Index

Judging by the daily plots, the "V" board that i put in the 'U' position
yesterday is still bad.

However, it appears that the adjustment of the U/W seems to have helped the 
spiking there.  I'll keep the fingers crossed.  Other differences in the
sonic data between this site and 1/2 may be attributable to different field
types and conditions.

125: EVE, Site 1, Fri 28-Jun-1996 14:05:25 GMT, Vbatt still bad

• Index

The Vbatt monitor in station 1 is still sawtoothing badly even though with
the kludge config EVE is now only sampling the TSFC and Vbatt channels (0 and
4).

Even though the TSFC looks OK, I probably need to take out the AD monitoring
of Vbatt.   What i may do for giggles is to get rid of the channel-0/Vbatt, but
put back in the load current instead to see if it glitches on channel 2 also.

Station 3 Visit: 20:25-21:45Z, 96/06/28 JD180

Reason:	The "V" board that was put into the 'U' slot yesterday was still
	spiking heavily.  I called ATI about this and... 

ATI Hints per Gary Zimmerman
	Regarding the problem with the "V" board, Gary 
	is sending another board overnight if he has a chance to finish
	going over it.  It is one of those sent back earlier.

	Internal ATI Slash / Filter Commands, not in the manual (Apx A)
	/SM	Median Filter
	/SA	Averaging Filter
	The median filter may work better to remove spiking and Gary
	recommended going to it instead of the normal 'averaging mode'.

	Signal Settings:
	The actual trigger threshold is at 2.5V
	We should not oversaturate the signal, as evidenced by the '2nd' peak
	getting all the way up to 12.  Gary said that it really is better for
	it to go anywhere from 8-12.  Absolute min. is 6V. 
	The filter cap also can be tweaked a bit to get the signal down.

	'W' component board can be attenuated more than the others, so a 'bad'
	or oversensative board can be put into that axis and tweaked down to
	help minimize spiking.

Major Changes to ATI Include:
	Set Sonic to /SM filter mode
	Swapped "W" board into 'U' slot
	Swapped "V" board from 'U' slot and put it in 'W' slot
	Adjusted signals as best i could.
	Zeroed more or less.  NOTE the chamber is really letting in too much
		wind .

Signal Quality
	I saw some of the 'phantom' noise signals on the "V" board in 'U' slot.
	These were generally less than 1V, but occassionally more.  The period
	was about the same as the trigger pulse.  The overall signal also was
	quite irregular but this may be attributed to wind getting through
	the zero chamber.   This board was pretty easy to adjust when it got
	to the 'W' slot, and the Signal looked a bit jumpy.

	I had a devil of a time adjusting the "W" board once it got into the
	'U' slot and played around quite a bit.   I still saw phantom signals
	on it, but i think i finally adjusted them out.  EVE was still getting
	spike hits though, but never > 1%

Conclusion:
	I believe we'll still see spikes in the 'U' data overnight even
	with the "W" board there.   That board had been spiking 2 days ago
	until i adjusted it in it's original 'W' slot.
	Need to watch both...

	Cnt	U   V   W	   
15:44				Swapped "W" into U.  "V" into 'W' slot
				Seeing lots of junk on W as well.
15:46	948	1   0   0		
15:48	2038	2   0   0	Attenuated "W" pot CCW.  2nd peak is now 8-10V
				Now the ghosts seem to be gone.  But i'm still
				seeing spike hits on EVE and the signal itself
				looks crummy.
15:51				Setting "V" board in 'W' slot.
				2nd peak is 8-10V.
				Zeroing "V" board in W,  34-deg, 27%
				Should be OK
16:20	2718	3   0   0	"W" board in 'U' slot.  Still seeing jumps
				in 1st peak up to 1.5V 
				and a bit of a 'phantom'
16:24	2692	7   0   0	Still adjusting signal.
16:40				Finally throwing up my hands, have done the

• Index

Station 2 Visit: 22:20-23:35, 96/06/28, JD180


TRH Fan Replaced
	This station had been having high temps.  I found the fan was dead, and
	wouldn't come back.  This is the same site where similar problems
	occurred earlier.  I replaced the fan in the beehive....what a nuisance
	to do.

EVE Not talking
	I never got the Compaq to cooperate with EVE.  It would see the EVE's
	messages but apparently never got a xmt through.  This had happened
	quite a bit previously, all over, and had been attributed to low/hot
	battery in the Compaq.  Even after powering down the Compaq for awhile
	and using the battery cable Matt sent, and recycling the Compaq, i 
	still never go into EVE.  I didn't have a gender change to try the RJ45
	direct console connection.
	NOTE: that this station has been having Freewave difficulty as well, but
	i think that's related to the lowered antenna at the base and a
	different radio xmit characteristics table than normal being used with
	these new replacement units.

TRH inner shield had dropped down about 1.5" since yesterday's visit.
I removed the shield and pushed it back as best i could, but it needs to have
larger screws put in the stripped housing.

Unbelievable!
Judging from the overnight plots, the sonic spiking at station 3 has greatly
improved to almost having nothing at all....wow.

So now, was it the /SM median filter mode, or the board swap, or the board
signal adjustment, or the big question: will it last?

• Index

The TRH inner shield tube was inserted fully so that no air could flow between
it and the outter tube.  The configuration was corrected, but there may have
been a small influence on the readings possibly, i.e. slightly too warm.

141: EVE, Site 1, Sat 29-Jun-1996 23:42:00 GMT, Temporary 'Iload' configuration

• Index

The temporary 'Vbatt' and Tsfc only configuration that had been in at this site
did somewhat improve the Vbatt readings, eliminating the constant sawtoothing,
but the sawtoothing was still evident, and may still be attributable to the
EVE a/d servicing.

A new temporary config was installed today at about 19Z that sends only the
Iload and Tsfc values.  This is a different form of the same sampling test,
but just a different pair of a/d channels 2 and 4 instead of 0 and 4.

Buried about 4" more of the Tsoil cable to see if there was any heat conduction
from that to the sensor that was causing greater variations during the day.
However, the corn rows are oriented E-W and it is possible to observe leaf
shading that 'comes and goes' as the sun transits.  (see station photos)

Uploaded Data.

EVE communications had been down at this site, both the console and the
Freewave weren't receiving input.  The Freewave appeared to be powered down,
i.e. no lights.  Tested the power connector and it was OK.  Tied the serial into
the compaq and saw the polling messages.  Plugged the entire box back together
and it all worked again.  I'm not sure what happened because the EVE continued
to collect data and GOES report, but it would appear that the Freewave somehow
locked up which probably effected EVE's console as well.

GOES will be down for awhile at this station.
I managed to blow the main box fuse when testing for the Freewave power.  The
take-off connector was taped so that hopefully this doesn't happen again.
However the only fuses on hand were 2.5A, not enough to run the entire station
plus the GOES transmits.  Tomorrow a new fuse will be installed.

 The BPH at station 3 is much better. I replaced the fan and
taped up the connection between the 50Y and the limo. There were
exposed wires. The BPH was then mounted at the 2m height and
monitored for awhile. The temperature readings were about 0.3
degrees lower than the TRH. The sensor was then mounted on the
ATI boom.
 I am not totally convinced the problem was the fan. If time
permits I may put the orginal fan back to try an isolate the
source of the problem.

a number of spikes on "u" throughout the night. In addition
"w" went down at 9:00 GMT this morning. I guess I'll just

 Coments: W showed alot of spikes via EVE thru terminal. On the scope
 the signal looked ok. Reset EVE, all was fine!  I monitored thru EVE
 for 50 minutes. The maximum number of spikes in 5 minute block was 3.

		visit time: 17:30 - 18:30 GMT

  The first thing was to look at the "w" vector. I hooked up
the scope and the signal looked fine. The peak level of the
2nd pulse was above 8 volts. Using EVE, it was seeing spikes
at a 10hz rate!  So I reset EVE. The sonic response, thru EVE,
now looked fine. So something happened in the EVE firmware.

  With respect to the "u" vector, I turned the gain back up
so the second pulse was above 8 volts. This was done with winds
around 3 m/s. I then spent the next 45 minutes monitoring the spike
count thru EVE. Over this time period I did not see a 5 minute
count greater than 3. 

  At this point I decided not to play with anything and let the
system run for another 24 hours.

Winds
             Speed difference:
             Direction difference: There was a perturbation 3 Jul ~ 0900 for P2

Pressure
             Pressure difference: Steve Oncley says
             If I've located them correctly, the elevations are:

             PAM1: 698' = 212.8m
             PAM2: 211.8m (note: map elevation is in meters!)
             PAM3: 212.3m

             Thus pressure from PAM1 should be a bit lower than PAM2 and PAM3
             by about 1m = 0.13 mb (1mb = 8m)...Steve


Temperature

             Relative Humidity:For the nighttime 1 Jul - 2 Jul the relative humidity
                               for P3 quite different to that at P1 and P2
                               This could be because of the crop difference

Rain
             PAM1: No rain
             PAM2: No rain
             PAM3: trace

Radiation Jul 1 cloudy, Jul 2 better and Jul 3 a good radiation day

             Moisture: P1 < P2 < P3 I would think that P3, the bare soil would be driest

             Heat fluxes: P3 still has the greatest heat flux

      
Energy Budgets
             PAM1 
             PAM2 
             PAM3 
             For all station it is the water vapor or latent heat flux which is the 
             most irregular. Probably the best approach will be to determine L by difference.
             This will require assumptions.

• Index

Installed new software on the Matrix card. Writes to the ingest output
socket in the sync task are now non-blocking, so the adam does not crash if
the network connection is jambed.

Samples can be lost when the network is jambed, however.  To see the total
count of lost samples, do

	sshow cosmos 0

You'll see output like so:


c:000 cosmos mem:131572 nent:153 nlost:0 nlate:0 pS:0 pD:0 dT:5410 msec, blocked:0, lost:0, writerr:0

The last three parameters (blocked, lost, writeerr) result from network jambs.
They are totals since the last adam reboot.

If the network is jambed for more than two minutes, then ingest will
timeout and shutdown, in which case the adam will need to be rebooted.

             Moisture: P1 < P2 < P3 I would think that P3, the bare soil would be driest

             Heat fluxes: P3 still has the greatest heat flux and P2 shows the effect
                          of sunshine penetration only near noon.

• Index

The latest code was being too verbose with errors messages from the adam
to the console.  The newest sync will only log an error every 100
lost samples, not every 100 blocked writes, as before.

The size of the output sample buffer was increased from 8192 to 16384 bytes.
The write threshold is 4096 bytes, meaning writes of 4096 bytes
are attempted when 4096 bytes are available (or 10 seconds have
passed since the last write).
Samples are not discarded unless the buffer would overflow, at 16384 bytes.

221: ADAM/NETWORK, Site ASTER, Wed 10-Jul-1996 00:06:12 GMT, Adam slip network jambs

• Index
• Graphics file: X Window DumpX Window Dump located in file: log_00221-1.gif

Two new data variables are now available from the adam:
	blocked.cosmos		# of blocked socket writes/second
	lost.cosmos		# of lost samples/second

These can be displayed by cockpit and xstrip.  They are also
averaged in the covar files.

From the attached plot, you can see that network jambs are occuring every 
5 minutes. It is not exactly 5 minutes however. They occur in groups of 6,
with five spikes spaced 4 min 40 seconds apart, and then a longer gap of
about 6 minutes 30 seconds, so that the entire group takes about exactly 
30 minutes.

I made this plot from Splus:
	> fun.plot.prep(c("blocked.cosmos","lost.cosmos"),1996,191)

(Day 191 is Jul 9).

Since they are not spaced exactly 5 minutes apart, it does not apear
to be timed with the pam polling process.  To further exclude pam
as a suspect, John suggested that I shut down eve_rf on cocklebur.
I shut it down from 00:21 to 00:34 on Jul 10.  The blockages
still occured, so pam is off the hook.

Could it be a profiler?

A useful diagnostic is to display "blocked.cosmos" with xstrip, and set
the options->chartwidth to 3000, which results in a grid line every 10
minutes.

                 the same roughness would be observed).  Also, a dirunal

             stability (z/L) (from weather plot):  stays less than 1

                heat is not too large.  Very stable (often > +2) during

             The cloud development in the late morning is pretty dramatic -
             it will be interesting to build a picture of the entire

        Direction difference: Most difference is between PAM1 and others

Pressure
	PAM1 smaller by 0.2mb, should be PAM2-1=0.13mb, PAM3-1=0.07mb
		based on elevations given in earlier 1-2 Jul status comment
		(the positions those were based on are correct)

Temperature
        Differences: Bandpass on PAM1&2 higher because hygt is close to
		corn canopy
                         
Humidity
        Relative Humidity: Biases make interpretation difficult.  PAM1 shows
		diurnal change in sign of gradient

Rain
        PAM1: showed large spike (not real) at 21Z today (13 Jul)
        PAM2: okay
        PAM3: showed large spike at 2Z on 12 Jul (probably not real)

        Solar radiometers:

Dirt         
        Temperatures: PAM1 increases like PAM3 in the morning, presumably
		due to E-W furrows.
        Moisture: PAM3 moister, possibly the corn takes more from the soil.
		(Steve S. says that the soil samples agree with this trend)
		Another possiblity is different drainage, but I doubt this.
        Heat fluxes: PAM3 varies most, as expected.

  Based on the last few days, the sonic at 3 has been spiking
due to changes in temperature (refer to earlier logbook entry).
This may not have been noticed at station 2, when the electronic
box was there, because the box was shaded by the corn. We moved
the sonic such that it is now on the ground under the PAM electronic
box. A 2' x 2' metal plate was put on top of the box for added
shielding. The sonic was zeroed on all axis.

266: SONIC, Site 2, Mon 15-Jul-1996 16:03:44 GMT, Typo in sonic.config.S

• Index

Due to a typo in sonic.config.S, the boom azimuth change on July 3rd of the
pam 2 sonic was not used in the the daily plots.

The S code looked like: 

   if (t2 > utime("1996 jul 3 16:30"))
        booazm <- c(boomazm[1], 214.0, boomazm[3])

booazm was being set, instead of boomazm. As a result the azimuth change from
215.2 to 214.0 was not corrected for in the dailyplots from July 3rd to 
July 9th.

The problem was noted and corrected on July 10th.

267: RAD, Site 1, Mon 15-Jul-1996 16:29:00 GMT, cleaned radiometers

• Index

Just cleaned mud(!) off the Licor and also cleaned the Q7 dome while I was up
there.  The Licor was caked with lots of mud - I can only speculate that
birds have carried some up there while working on their meals.

I used toilet paper and saliva as the cleaning agents and think I did a 
reasonable job, but others reading this comment may want to let me know
if they think I should reclean the radiometers with something different.

It was a good view of the site from there - see the next comment.

268: STATUS, Site 1, Mon 15-Jul-1996 16:33:37 GMT, field characteristics

• Index

The corn has been flattened in many areas.  There are groups of 1-10 plants
which are now leaning severely or even flattened after yesterday's rain
at this site.  It could be associated with the wind or heavy rain, but I
suspect it may just be that the now wet soil isn't supporting the weight
of the plants well.  I tried to step carefully (not easy when carrying a
ladder) to avoid damaging the crop further.  [I plan to take some pictures
today.]

Also note with this site that the hay area which was moved significantly
changes the fetch from the north (which would have been different anyway).
Fluxes when winds are within about 30 degrees from north should not be 
interpretted as representative of corn.

Something else we noted in PAM's Compaq log yesterday - one egg at station 1
has hatched, so we now have a hungry chick!  We're trying to avoid further
visits - at least to the tripod area.

P.S. We may want to add another logbook category for this type of comment.

269: SOFTWARE, Site base, Mon 15-Jul-1996 16:52:15 GMT, avoiding crashes in dplot

• Index

There are several plots which combine several variables (weather, energy 
balance) which die with "length not a multiple..." errors and exit dplot.
This happens when "Plotting Recent" while the netcdf files are being updated.
We could spend a lot of time modifying the plot codes, but in the meantime
there are two workarounds:
1. Don't make these plots at these times (easy to know because the RASS also
goes off at the ppf->netcdf update times!)
2. Use "Plot" rather than "Plot Recent".
Running the plots manually (not window-driven) avoids having to clean up
the dead windows when this occurs.

270: LOG, Site all, Mon 15-Jul-1996 19:56:11 GMT, roughness lengths

• Index

Here are some very crude estimates of roughness lengths.  I have made an
eyeball average of the u*/spd daily plot for the last 10 days and get
u*/U = 0.07 (beans) and 0.11 (corn) for daytime values.  Since these
values are pretty steady, I assume they represent neutral conditions also,
so we can say:  u*/U = k/ ln(z/zo).  Letting z=10m (beans) and 8.4m (corn),
I get zo = 3cm (beans) and 22cm (corn), which seems a bit large.

PAM2	-3	0.4	0.6	0.7	126.1
PAM3	-5	1.5	-0.3	1.6	-169.0

Note that the PAM2 plot was pretty scattered, probably because we
changed the tilt after zeroing it Saturday.

All of these values are acceptable to me.

Status of the FLATLAND96 data set for 14-15 Jul'96

Weather plots
	No surprises:
        - rain on the morning of the 14th and night of the 15th.
	- strong (8 m/s) winds during the 14 associated with the rain
	  otherwise, persistently about 4 m/s from SW (where the sonics
	  are aligned to) thus stabilities have been close to neutral
          (|z/L| ~ 0.3).
        PAM3: Stronger latent heat fluxes now that soil is moist,

Dirt:          
        Temperatures: A few degrees lower now that the soil is wet
        Moisture: Wetter (obviously).  I've worked up the gravimetric
		samples, but a comparison is difficult since the PAM
		probes are % by volume.  We'll try to make a soil density
		measurement.  We also note a diurnal variation of up to
		5% at PAM3 (also noted by Tom).  Tom's CSI615 correction
		code appears to do the right computation, but the
		correction is at least a factor of 3 too small to explain
		this cycle.
        Heat fluxes: Seem reasonable, quite large fluxes at PAM3.
      
Winds:
	PAM3: Higher winds since z-d=10m, rather than 8m at 1&2
        Directions pretty consistent, with biggest difference between
		PAM1 and 2&3 (to be expected).  Also some expected differences
		in light winds.

Pressure: Larger variations than earlier during rain - probably real.

Temperature:
	Generally somewhat cooler since cold air associated with the rain
		(or should this be vice versa?) came in.
        Differences: Hygt is cooler IN corn than OVER beans, which is to
		be expected.
                         
Humidity:
        Relative Humidity: Most sensors have been saturated after rain.
		Some odd differences between PAM1 and PAM2.  We expect
		PAM2 hygt to be large (especially at night) since it
		is in the canopy, but both hygt and bph at PAM1 are also
		relatively high.  We need to look at the biases from the
		Assman IC to interpret these differences.

Sonics/fast scalars: No changes from previous days. It is surprising that

        u*: 
	Drag Coefficient:

Sonics/scalars
	sigma Tc, wTc: PAM3's higher sigma Tc is offset by lower sigma w, so
		fluxes are about the same as the other sites.  
		(Since latent heat fluxes at PAM3 are lower, and net is the
		same, the rest of the heat is going into the ground.)
        sigma H2O, wrH2O: Why do the daily plots use hygt and not bph as a			    reference?  I may change this.

280: OZONE, Site 1, Tue 16-Jul-1996 21:40:03 GMT, chem shelter in place

• Index

We've just installed the chem shelter about 1/2 way between the tripod and
the adam at station 1.  We removed 5 corn plants to get it into its present
location.  We also knocked down about 1 plant/row getting it in place, which
we attempted to straighten.  power, and data lines are now connected - we
plan to put the Datel voltage calibrator on some of the channels later
(perhaps even tonight).

I agonized over this location for the shelter, and actually pulled up another
5 plants (which I also attempted to replant) at the tripod itself when I
was initially thinking of the chemistry needs (short tubing) only.  The
present location should be reachable by a 10m inlet tube.  My concern about
getting closer was that the heat exhaust of the air conditioner could 
contaminate the hygt sensors.  Also, the first location was very close
to the pressure port (would it induce a flow anomoly?) and close, but not
in, the surface temperature field of view.

I am simply weighing the samples which Steve took on 7/15, assuming that
he cut out a perfect 5cm x 5cm x 5cm cube.  Obviously, this should be
done with dry soil to get the dry soil density, but I wanted to use the
oven to process the samples we took today.  Thus, I dried only the sample
from PAM1 for only about 4 hours.  This measurement was further complicated
since I used a plastic plate which melted (slightly) in the oven.

This one (partially dried) sample weighed 308g - nearly the same as the
samples from the other 2 stations which have simply been sitting exposed
in the trailer.  308g/125cm3 = 2.46 g/cm3.  I'll get some metal pans and
try drying these (and today's) samples more tomorrow after the "dry"
weighing of today's samples.

286: SOFTWARE, Site base, Wed 17-Jul-1996 21:08:18 GMT, Correction to fun.qsoil.plot

• Index

I found that the temperature coefficient for the CS615 needed to
be multiplied by 100 in fun.qsoil.plot.  I have made this correction
and changed this routine to plot only the corrected data if CS615=T.
This is now the default in fun.soil.pam.

The temperature correction now appears to eliminate the diurnal cycle
in the soil moisture at the lower soil moisture values found at sites 1
and 2 (10-20% by volume).  It is insufficient at the 30% soil moisture
being measured at site 3.

287: RAD, Site all, Wed 17-Jul-1996 21:17:27 GMT, cleaned/leveled radiometers

• Index

During our site visits today, I checked the radiometers (by ladder) at 
PAM2 and PAM3.  Both nets were a bit dirty (3 had bird poop and 2 had mud
drops), so I cleaned them.  I also gave the Licor's a wipe, though they
looked pretty clean anyway.  

I also releveled both nets.  PAM3 had been pointing up to the SE by about 
1/2 bubble and PAM2 had up to the E, by an unremembered amount.  Both 
Licors were level.

Both radiometers on PAM1 were pointing up to the NE by about 1/3 bubble
when I cleaned them 3 days ago.

289: GOES / RF, Site 2, Thu 18-Jul-1996 16:05:27 GMT, PAM2 now using patch antenna

• Index

John M. called to tell us that PAM2 is transmitting too much power to GOES,
so we switched back to a patch antenna (from a yagi).  Since John had problems
with the patch antenna on PAM2 earlier (which is why the yagi was installed),
I first swapped patch antennas on PAM1.  So, the sequence was:
Station 1:
0951: measured original patch power: 8.7 forward/0.1 reflected
Swapped patch antennas (lost a nut in the process)
0956: measured new (PAM2 original) patch power: No change.

Station 2:
1027: measured yagi power: 7.6 forward/0.3 reflected
1032: possibly a bad transmission, since I was still struggling with
tightening the patch mount
1037: measured patch (PAM1 original) power: 10.7 forward/0.1 reflected

Hopefully, John will keep us advised.

290: SOIL, Site all, Thu 18-Jul-1996 18:42:41 GMT, CSI615 comparison to gravmoist

• Index
• Graphics file: CSI615 and gravmoist soil moistureCSI615 and gravmoist soil moisture located in file: log_00290-1.gif

There now is a function "fun.add.gravmoist", (in $ASTER/apps/sfun/FLATLAND96)
which overplots gravimetric soil moisture values on a plot made by 
fun.qsoil.plot, assuming a constant soil density for all 3 sites (currently
set to 2 g/cm3 to make the data work out - I should have a better guess
tomorrow after soil samples dry out).  A call to this function is loaded
into the dplot menu.  I chose not to have this function called by 
fun.qsoil.plot itself, because fun.add.gravmoist is not general-purpose for
all projects (yet).  Please see comments at the beginning of this function
on how it grabs the gravimetric values - it is pretty clumsy.

The comparison is quite variable, with a hint of a gain error, i.e. values
of soil moisture from the CSI are too high when q ~ 15% and too low when
q ~ 30%.  It also is not obvious that PAM3 is any worse than the other
two stations.

I've inserted the plot into this comment, so others can see what I've seen.

Status of the FLATLAND96 data set for 16-17 Jul'96

(Sorry this is late - we have been having daily plot crashes, which takes
manual recovery.  We have edited crontab to try to avoid these in the future.

Weather plots
	No surprises:
	- healthy winds (6 m/s) on the 17th (and today too) thus stabilities 
		have been close to neutral (|z/L| ~ 0.1).
        PAM2: Showing lower latent heat fluxes than PAM1, but w:rH2O 
		compares well.  The fluxes should be large.

Dirt: All okay - see previous comments about soil moisture
        Temperatures:
        Moisture:
        Heat fluxes:
      
Winds: No surprises

Pressure: Similar to previous periods

Temperature: No surprises

Humidity:
	Some saturated periods evening 16-17.  Otherwise okay.
        Relative Humidity: We still need to look at the Assman IC data.

Rain
        PAM1: spike at 21Z on 13 Jul was data problem
        PAM2: 
        PAM3:

Radiation: No surprises - all domes have been cleaned recently
        Net radiometers:
        Solar radiometers: PAM1 still reads negative at night.  We're
		still debating replacing it with the ISS spare (there
		are some interfacing issues).

Energy Budgets
        PAM1 
        PAM2 
        PAM3 
                 
Sonic flags:  We're pretty happy with this performance and won't change things.
        PAM1: Got a few spikes overnight last night - still not too bad.
        PAM2: Still light spiking on u.
        PAM3: Just a few spikes on w, despite high temps.  Steve's latest
		board swap may have done the trick.

Sonics/fast scalars: 
	speed/dir: There is now a 5 degree difference between sonic and
		prop directions - perhaps this occured during the strong
		crosswinds on 14 July, though it isn't obvious - we'll
		put reshooting the directions on our list.

Sonics/scalars
	sigma Tc, wTc:	PAM1 tc spikes over most of 17 Jul probably are a 
		problem with the despiking routine - tc:tc variance also 
		different between pam1 and adam1.
        sigma H2O, wrH2O: 
	- w:rH2O is not consistent with fluxes in wx.plot.  I'll check this.
	- Krypton now about 3 g/m3 high - We plan to clean it tomorrow.
	- bph and krypton variances agree well (except at night).  bph fluxes
		are lower, as expected.

changing to a centrex system).  Anyway, we have been switched to a new
number: 344-5876, so I updated /etc/dp/dp.conf.  I couldn't figure out a
graceful way to stopdp (I thought there was a command by this name, but I
couldn't find it), so I "kill -9"'ed the process and restarted it using
/etc/dpctl.  This appeared to work.  net66 said that they also changed us
off of the latest modems "...tech" and onto a Motorola one.  I noticed
that we are now back on at 21600 baud.

I hope the line is stable from now on...

It has become apparent that we want a command to look at recent data from the

but not here (even when using the ppf= option).  As a temporary cludge, I
have created the aliases in the aster account: "last1", "last2", and "last3" 
which run the "last" command on stout for each pam station.  This serves our
need for the moment.

Status of the FLATLAND96 data set for 18-19 Jul'96

(We are still having daily plot crashes, but I now have a "redo_dailies"
script which does the ones which bomb.  I'm still not sure why this is
necessary.  The crontab change didn't work.)

Weather plots
	The 19th was interesting: A forecasted storm to the south never
	materialized, but there was a continual shift from SW to NE flow.
	We are now in a cooler (20 C) drier (10 g/kg) flow from the Great
	Lakes.  It was a tough tailwind for yesterday's bike ride home,
	but great this morning!

	|z/L| generally 0.1 or less.

Dirt: All pretty normal - we still have doubts about moisture.
      
Winds: No surprises

Temperature: No surprises.  Both the temperature and humidity difference
	plots are hard to interpret because biases in the sensors are of
	the same magnitude as the differences between 2m and 3m (or 6m).
        If we want to use these differences, biases of the T/RH sensors
	need to be characterized.  (We have done 3 sets of Assman ICs on
	the hygrothermometers, but the results from these ICs don't appear
	to help the interpretation).  Steve S. suggests running bph and hygt
	at the same level for a day during tear-down.

Humidity: Cleaning the bph sensors makes bph and hygt agree more (though the
	comparison is getting worse again)

Pressure: Similar to previous periods, though last evening, the differences 
	were smaller.  There is a weak correlation between strong, North
	winds and smaller pressure differences between stations 1 and 2&3
	looking at previous data.

Radiation: 
        Net radiometers: The dramatic drop in the magnitude of net overnight 
		last night at 06Z probably is real, associated with clouds
		moving in.
        Solar radiometers: The replacement of the PAM1 sensor appears to
		have fixed our negative nocturnal radiation.

Sonic flags:  Staying relatively stable
        PAM1: Continuing to see Tc spikes on EVE
        PAM2: Still light spiking on u.
        PAM3: Pretty good.

Sonics/fast scalars: 
	speed/dir: The 5 degree difference between sonic and prop directions
		is not from the sonic.  We'll read check the prop direction
		next time we drop PAM1 or PAM2.
	w: PAM3 apparently is tilted, since a 20 cm/s bias switch sign after
		this wind direction change.  I computed a pitch angle of
		1.5 degrees last week - I'll do another check of tilts soon.
	second order moments: all normal

Sonics/scalars
	sigma Tc, wTc: Again, large variance differences between ADAM and
		EVE computations when EVE detects spikes, but less effect
		on the fluxes.
        sigma H2O, wrH2O: Krypton cleaning yesterday fixed bias differences.

Overall:

316: ADAM/NETWORK, Site 1, Sat 20-Jul-1996 19:42:57 GMT, Cosmos back on the air

  Cosmos is back up. During the bootup period there was no
noise seen on the profiler. Will monitor the profiler.

317: SOIL, Site all, Sat 20-Jul-1996 20:02:43 GMT, new soil densities

• Index

Well, I've just weighed the 7/17 samples which I dug out and get:

PAM1	167.57g		1.34 g/cm3
PAM2	243.97g		1.95 g/cm3
PAM3	152.39g		1.22 g/cm3

I think the PAM3 sample ended up small, though I don't know why, so it should
be discarded.

These numbers are obviously quite different than those from the 7/15 samples
which Steve S. dug out - perhaps he extracted more than 125 cm3.  I am
tempted to say that there was some other problem with the PAM1 sample, and 
that a density of about 2 g/cm3 is okay.  We may want to get/make a core
sampler to more accurately extract a fixed volume.

318: SONIC, Site all, Sat 20-Jul-1996 22:55:12 GMT, last week's tilts agree w/previous

I just computed tilts for the last week, which look similar to the previous

that we will try to level it tomorrow.

327: OZONE, Site 1, Mon 22-Jul-1996 22:44:01 GMT, ozone installed, but not running

• Index

Greg Kok and I spent most of the daty setting up his ozone sensors.
Everything is now installed, but he doesn't have the NO flowing, (because
he wasn't able to get dry ice today), so there is no fast ozone signal.

He now has:
- two inlets strapped to the BPH tube, 
- sensors in the chem shelter Steve S. and I installed,
- a big pump sitting on the transformer box with the outflow going through 
a garden hose which exhausts on the east side of the darkhorse,
- a bottle of NO laying in the "clearing" along the access path, connected
to the chem shelter by a length of thin stainless steel tubing.
[A lot of stuff scattered around this site!]

We had some trouble with "brown-outs" on the power.  I switched power
cables between the adam and chem shelter, resulting in (actually several)
reboots of cosmos.  After talking to Kurt, I think I have the best load
distribution I can get, but I'll try to measure currents tomorrow.

328: LOG, Site 1, Mon 22-Jul-1996 22:51:45 GMT, Tower was down about 18Z today

• Index

We dropped the tower (with both robins) today to install the ozone inlet.

As long as it was down, I cleaned the krypton (which was filthy - I think
the robins are sabotaging it!).  The krypton signal level looks pretty good
now.  

I also opened up and popped the connectors on the BPH (at Steve S.'s
suggestion) to try to reduce the noise we've seen on the temperature.
It looks somewhat better, but I'll give it more time before declaring
it fixed.

329: ADAM/NETWORK, Site 1, Tue 23-Jul-1996 15:21:25 GMT, cosmos died last night

• Index

Cosmos died about 0745 last night with "ingest socket write to aster.8000"
errors.  In the confusion of introducing Matt, Greg arriving, and Lou calling,
I neglected to check_aster or look at the log file to isolate the problem.
We rebooted it about 40 minutes ago and it seems to be running again.

330: LOG, Site 1, Tue 23-Jul-1996 15:24:15 GMT, station 1 electrical power

• Index

Since we had some brownouts yesterday, I made some power measurements - the
quick summary is that we seem to be balanced perfectly:

Greg's pump (off one side of the transformer): 8.2 A
The chem shelter, with air conditioner and ozone (off the other side): 4.5 A
Adam and PAM: (also off the other side) 3.5A

Thus, 8.2 A of the pump is balanced by 8.0 A of the other stuff.  This is
well within the range of the 20 A breaker on the input and 15 A breakers on
each of the outputs of the transformer.

(Therefore, the cosmos crash probably wasn't power related.)

331: SOIL, Site all, Tue 23-Jul-1996 19:32:11 GMT, soil samples and crop heights taken

• Index

Soil samples were taken and crop heights measured at sites 2 and 3 - a
day late by Steve S.'s schedule because I was busy yesterday.  See
entries #35 and #39 as usual for the results.  The south bean plot at
station 3 is beginning to grow in, and the ears are developing nicely
at station 2.

According to Tom's rule of 3.0m < sonic-crop < 3.5m, it is now time to
raise the #3 sonic.  We've put it on our list for tomorrow.

332: EVE, Site 1, Tue 23-Jul-1996 20:42:48 GMT, cpu swap and new config to fix A/D chan.

• Index

Swapped cpu board at station 1.  New board is the extended temp range
board.  Changed config to read all the A/D channels now.  New config
with old board definitely gave garbage: got 5.4V on the power.  New
board gave about 13V on the power.

333: OZONE, Site 1, Tue 23-Jul-1996 23:15:15 GMT, TECO was cleaned this afternoon

• Index

Greg didn't like the TECO output, so he cleaned it this afternoon.
The data now look pretty stable to me, but Greg plans to return this
evening to look at it.

334: OZONE, Site 1, Tue 23-Jul-1996 23:26:20 GMT, added t.shelter.0m

• Index

Greg wants to monitor the temperature in the chem shelter, so I've given
him another channel (106).  I changed archive, prep, covar, and channel
configs in $OPS1 and am now rebooting cosmos.  Hopefully, everything will
come up well, since I want to leave soon for the day.

336: ADAM/NETWORK, Site 1, Wed 24-Jul-1996 18:13:35 GMT, cosmos crashes

• Index

We came in this morning to find that cosmos had crashed again, with network 
error messages in the "asterlog" file which were similar to those from 
previous crashes.  I rebooted (with the key, since it didn't ping), and
it crashed again in about 2 hours.  We have taken the following steps:
1. "niced" the pam ppf2netcdf process, which may give the network handling
higher relative priority
2. removed a lot of the error messages in "sync.cc" to avoid the network
being "message bombed" when a crash starts.  We have noticed that once
cosmos gets one sample that doesn't get through that a crash is imminent.
3. We looked at the statistics on the freewave in the trailer which said
that only 57% of messages were received.  However, we don't trust this
number, since Matt got 9% when he repeated it, and 0% on the pam modem.

After discussions with Steve S., there are many more options - some harder
than others - depending on what the source of these crashes is.  At this
point, we don't know if the problem is aster being overloaded, the RF link
not being reliable (or being interfered with) or a power glitch (our only
guess as to why it is worse now that Greg is here).

P.S. it crashed again while I was typing this!

LIFT Ozone Operating Instructions:

GENERAL WARNING:
Whenever entering the cornfield listen for operation of the sample
pump.  If the pump is not operating, do not proceed.  Position
yourself upwind of the pump and fast ozone instrument, go to the NO
cylinder, and turn off the NO cylinder and regulator valve.  Exit
the corn, wait 30 minutes for any NO to dissipate, go to the pump,
keeping yourself upwind of it, and attempt to restart it.  The pump
has an automatic thermal overload protection on it.  If the pump
cuts out, it will restart automatically when cool.  Use caution. 

TECO ozone instrument can be left on at all times.  Every day,
check that the instrument is on, the pump is on, and that the P/T
button is in.

FAST OZONE STARTUP:

1.  Fill PMT cooler with dry ice.  If you plan to operate
overnight, it will need a second filling at the end of the day.
2.  Turn on fast ozone control box.
3.  Turn on sample heater variac
4  Turn on high voltage for PMT (left side of instrument)
5.  Disconnect fast O3 signal lead (channel 0), and measure output
voltage with meter.  Record dark output voltage on log sheet. 
Reconnect signal cable.  The BNC connector on the signal junction
box is a bit loose, take care not to twist it when
removing/reattaching the cable.
6.  Turn on sample pump at breaker on transformer.
7.  Check pressure on fast ozone control box. Turn the rotary
switch by the meter all the way counter clockwise, that position is
blank. clockwise on click is NO flow, then sample flow, then system
pressure.
8.  Check sample flow.
9.  If sample pressure is greater than 120 and sample flow is less
than 300 do not proceed.  There is most likely a problem with the
sample pump.  Wait a few minutes to see if the flow/pressure
improve.  Otherwise check for leaks.
10.  Turn on NO cylinder valve and regulator valve.  Record
cylinder pressure and regulator output pressure.
11.  Check NO flow at instrument and record setting and NO flow.
12.  Record shelter temperature and instrument temperature.

SHUTDOWN:

1.  Close NO cylinder valve and regulator valve.  
2.  Turn off high voltage to PMT tube.
3.  Turn off fast ozone control box.
4.  Remove any remaining dry ice from the PMT chamber.
5.  Make sure that the pump has run for at least 10- preferably
longer, 20 + min after the NO has been shutoff.  Then shut the
sample pump off.

Installation and operation notes-fast ozone in LIFT/FLATLAND '96

7/22/96

Setup system in cornfield at FAO.  Install inlet line on tower. 
Each ozone instrument has separate inlet line.  Inlet line length
approximately 30 ft.  TECO inlet line has angle cut on the inlet
end.  TECO opertational mid day.  Large variation in O3 as measured
by TECO.  Cycling of air conditioner causes spikes in O3, probably
humidity problem.  Run fast ozone overnight without NO on and no
dry ice on PMT cooler.

7/23/96

Put dry ice on PMT and connect NO.  TECO still giving spikes in
data.  Approx 14:30-15:30 pull TECO out and change windows.  Found
traces of oil on inlet side windows.  Clean cells, check lamp
frequency and everything is OK.  Freq A=124,522, B=119,734. 
Insulate complete length on TECO inlet line.

Approx 18:30 shut system down, remove FO3 driver box and connect
other OMEGA temp readout to twinax on back for connection to data
system.  Reinstall entire unit operational about 19:30.  Run FO3
overnight with PMT cold, and no nitric oxide.  Data system crashed
about 22:30 local time.

7/24/96

Insulated end of heater and reactor for fast ozone.  Put dry ice on
system.  Started NO about 09:00.  TECO data looked good last night. 
Rained at least once during the night.  Discussions with persons at
the DIAL O3 site indicate spikes in TECO measurements.  Need to
check if they correlate with PAM 1 measurements.  System shut down
at 17:30 to check if operation causes datat system to crash.  Data
system crashed once during the night, so ozone system is not the
cause.

7/25/96

Start TECO and fast ozone.  Fast ozone pump sounded a bit stiff
when starting up.  

344: OZONE, Site 1, Thu 25-Jul-1996 15:59:12 GMT, details of fast ozone operation

• Index

LIFT Fast Ozone Details:

Dry ice can be procured from the Community Blood Bank of Illinois,
1408 University, Champaign. (367-2202) Hours are 8-4 M-Th and 8-5
on Fri.  They typically get deliveries of dry ice on Tue and Fri.
The price is $0.65/lb.  Give them the NCAR tax exempt number 98-
02203 and they will not charge sales tax.  We need about 5 lb of
dry ice per day of operation for the PMT, plus evaporative losses
require an amount of about 7-8 pounds a day.  

The chart recorder is running on the TECO.  I suggest we leave this
run.  Note the time on the chart every day.  There is a mark button
on the upper right corner of the flatbed, punch this and note the
time on the chart.

If it looks like the TECO needs cleaning, use care when cleaning
the windows.  They scratch easily, and that causes problems with
water vapor interference.  If the instrument is cleaned pay special
attention to the teflon flat washers and the rubber gaskets around
the windows.  Clean these really well with alcohol and then dry
them by pressing in a paper towel.

If the fast  ozone has a high background signal, the most likely
problem is a wet PMT.  Keep track of the background "dark voltage"
each morning and that is a good indicator if you have a problem. 
Make sure the PMT chamber is up to ambient temperature, pull the
back off the chemshelter, this is much easier than getting the
instrument rack out and getting access to the back of it. 
Disconnect the cables from the PMT socket and pull the three screws
that hold it in.  Gently pry the socket out, handle the PMT only
with a paper towel between it and your hand.  Put the socket in the
oven for an hour or so at 40 deg, use the heat gun to gently dry
the housing.  Assemble the PMT and the socket in the dry of the
trailer, wrap the assembly in paper towels and return to instrument
for reassembly.

There is an additional cylinder of NO in the chemshelter.  Use this
if necessary.

System Checks:

Every two days, run a power spectra analysis and a cospectra on the
fast ozone.  Look at these and keep track of them to validate
instrument performance.

Weekly (preferably on Wednesday) check the frequency on the TECO
lamp.  Push in button A, wait for a number of about 100K or
greater, then do B.  Then push RUN to the instrument back to
regular operation.

345: LOG, Site none, Thu 25-Jul-1996 17:54:53 GMT, Calculation of white noise

• Index
• Graphics file: O3, H2O, Tc, and w spectraO3, H2O, Tc, and w spectra located in file: log_00345-1.gif

Since Greg would like us to look at ozone spectra, I thought it would be 
useful to review here how to obtain values for white noise levels.
Since white noise, by definition, has the same amplitude at all frequencies,
its total variance is simply the average amplitude of the spectra where
noise is observed (usually the high frequencies) times the bandwidth of the
data.  The bandwidth of the data is from 1/averaging period, which is usually
small so we call it 0, to the Nyquist frequency.  However, the Nyquist 
frequency also is the highest frequency plotted on power spectral plots.

THEREFORE, the variance due to white noise is simply the amplitude of the
power spectra at the highest frequency (usually 5 or 10 Hz) when plotted as 
frequency * spectra (which is the default in fun.plot.prep).  The standard 
deviation is the square root of this variance.

For example, the attached spectral plot from an hour ago shows white noise
on conc.O3 with a variance of 0.002 V^2, which gives a standard deviation
of 0.04 V (or 0.8ppb with Greg's nominal gain of 20).  This is the same value
that we saw a few days ago when Greg installed this instrument. 
h2o.csi has no white noise (yeah!).  
Both w.atik and tc.atik appear to have noise at 0.025 (m/s)^2 = 0.16 m/s 
and 0.007 C^2 = 0.03 C respectively, but this is an artifact of combining
10 sample/sec and 20 sample/sec data.

354: OZONE, Site 1, Fri 26-Jul-1996 13:11:33 GMT, PAM1 mast dropped

• Index

Greg and I dropped the mast to perform the ozone delay time tests this morning.
(early to have the mast back up before the LIFT "intensive" period starting
at 8 AM (which includes the ozone DIAL system) ).

I also cleaned the krypton, which didn't look too bad.

Note that we did some weird things with the analog signals for this test:
The cable from channels 4-7 in the chem shelter was connected to channels
108-111 (thus no signals were coming in to channels 104-107 and the krypton
signal was disconnected).  This allowed us to use channel 108 for the
valve switch indicator.  Everything was back to normal about 1250Z.

P.S. We find 0.4 s for the delay time.  This could be a slight overestimate if 
the valve delay is significant (probably less than 0.05s).
This value is pretty close to 0.3s found from the krypton-ozone lag 
correlation.

356: SOIL, Site all, Fri 26-Jul-1996 14:34:44 GMT, more soil densities

• Index

From the last samples (7/22 & 7/23), the total (dry) sample weights are:

PAM1: 189.55 g => 1.52 g/cm3
PAM2: 177.24 g => 1.42 g/cm3
PAM3: 169.07 g => 1.35 g/cm3

The volumes I cut out did not look quite cubic.  I would guess that they
could have been either 5 x 5 x 4 cm = 100 cm3 or 6 x 6 x 5 = 180 cm3 
(rather than 5 x 5 x 5 = 125 cm3 used above).  Thus, the above values
probably are only good to +/- 30%.  We still need to get a soil corer
to sample accurate volumes.

(Matt thinks the volumes were 5 x 5 x 3.5 = 87.5 => 1.9 - 2.2 g/cm3)

	There was a broken ceiling through the night and into this morning.
	z/L was about -0.3 to -0.5 during the day, and greater than +2 
	overnight.
	Winds northerly yesterday at 3 m/s, changing to light and variable
	overnight.
	

Dirt: All normal
      
Winds: Okay.  It appears that PAM1 got "stuck" in the light winds last
	night more than the others.  This COULD be real, but probably
	indicates that the bearings in the wind sensor are worn.  We'll
	consider replacing it.

Temperature: Looks better with the fan working at PAM3.  
	However, with higher heat fluxes and lower u* at PAM3, I would
	have expected | T_bph - T_hygt | to be larger than at the other
	sites.  Furthermore, I would have thought that T_hygt at PAM2
	would be lower than normal, since it is completely surrounded
	by corn.  The data show delta_T greatest at PAM2 and least at PAM3
	which goes against my interpretation.

Humidity: Okay. Most sensors saturated overnight, which is consistant with
	our so-far unrecorded experience of finding the corn leaves covered
	with water (thus drenching anyone visiting PAM1 or PAM2) every
	morning.

Pressure: Similar to previous periods.

Radiation: 
        Solar radiometers: The PAM1 Licor is reading low.  This may indicate
		that another cleaning is needed.
        Net radiometers: Net is also higher on PAM1.

Sonic flags:  Normal
        PAM1: 7 spikes on u - some on Tc
        PAM2: Continuous light spiking on u and Tc.
        PAM3: 2 spikes on w

Sonics/fast scalars: 
	speed/dir: Okay.  Note that the PAM3 sonic is now a bit higher,
		so differences with the prop should be slightly smaller.
		The PAM2 sonic-prop directions agree again, without
		any servicing.  Perhaps something in the prop head rotates
		in strong winds.  Someone should check this.
	w: some strange things last night - the EVE data show digitizing
		resolution, but even cosmos shows variations with periods
		of 3 hours.
	second order moments: all normal

Sonics/scalars
	sigma Tc, wTc: Okay.  The fan replacement at PAM3 helped the Tc 
		comparison
        sigma H2O, wrH2O: Okay.

Overall:
	Things are going all right, but there are some questions to be
	resolved.

Note that the did name "conc.O3.teco.0m" is misleading.  Greg has a second
inlet at the sonic (currently 5.7m) to feed the TECO.  This did probably
should be conc.O3.teco.3m.  However, I don't plan to change it at this late
date.

• Index

We've just done the rounds of soil and crop height measurements.  See logbook
entries 35 and 39.

Matt noticed that the head of the soil moisture probe at PAM2 appeared to be 
exposed.  We troweled some dirt back over it and patted it down, but these data
should be treated as suspect from now on.

370: EVE, Site 1, Sat 27-Jul-1996 21:10:59 GMT, Ozone ingest to EVE

• Index

		C A B L I N G
		=============

Added cabling to T-off the BNC connector in the chem shelter and get
fast O3 into PAM.  Here is the O3 cabling info for PAM.

The AD-1 (chan 4--7) cable is used to connect the Ozone.  This
connector is also used for the Tsfc sensor.  Tsfc is on chan 4 .

The other end of the cable is an adapter to get from  BNC via:

BNC-T --> BNC-to-phono_plug --> cable

Red phono plug--> red/black wire pair --> 16 pin amp, ch 5 pins 4=+, 5=-, 
					6=shld.  pin 5 is jumpered to pin 6

White phono plug-->white/black wire pair --> 16 pin amp ch 6, pins 7,8,9

Blue phono plug-->green/black wire pair --> 16 pin amp ch 7, pins 10, 11, 12

Note: only channel 5 has the jumper from the negative side of the
differential input to ground.

Red plug goes to fast ozone  (EVE analog chan 5)

White plug not used (seems to have a short somewhere)

Blue plug used for Teco  (EVE analog chan 7)

There is a green piece of paper laying around with this information on
it.  It was officially placed in the thin white "technical" binder
pocket, but that doesn't mean it will stay there long.


		E V E   D A T A
		===============

Created new EVE configuration fmt0017.dat.  The new config has fast
Ozone (10Hz) and TECO Ozone.  Delay of 0.4 sec added to fast O3 for
covar parameters. 

Covars added are:

O3:O3
U:O3
V:O3
W:O3

Also output are:

O3.AVG  (also with 0.4 sec delay)

Teco.AVG (no delay) -- perhaps one should be added?

The fast O3 data is being output in raw volts; calibration is to be
done post-project.

The Teco ozone is output in ppb.  10V full scale is 1000 ppb.

Installed fmt0017 in station 1 and added cabling for Ozone.  See
previous message for Ozone tech info.  The new config also has
bandpass temp variance added as a new parameter.  Steve O. requested this.

See the attached plot for spectral effect of attaching the O3 sensor to EVE.

372: OZONE, Site 1, Sat 27-Jul-1996 23:01:27 GMT, ozone shutdown

Fast ozone shutdown about 10 min. ago since it might rain and the ozone
DIAL should have been shut down at 5:35.

373: OZONE, Site 1, Sun 28-Jul-1996 14:11:30 GMT, ozone restarted

• Index

All settings normal.

I notice from the daily plots that it takes a good hour for the fast sensor
to (literally) warm up and give values which agree with the TECO - we should 
keep this in mind when coordinating with the LIFT measurements.  (It is 
possible that the sensor temperature is an important part of the calibration
and that the output values will agree when the temperature is included,
but I am skeptical.)

374: ADAM/NETWORK, Site 1, Sun 28-Jul-1996 14:12:18 GMT, cosmos still up

We had light rain about 04Z at the Radisson last night, but none of the
stations saw it.

376: EVE, Site 1, Sun 28-Jul-1996 22:01:23 GMT, Data collection problem with fast ozone

• Index

The fast ozone data on the PAM station is only being collected
sporadically.  The symptom is that the data synchronizer on EVE begins
flushing data.  This may mean that some part of the data collection is
not keeping up properly.  A possible test solution is to temporarily
remove the sonic despiker and free up some processing.

It's also possible that there is a bug somewhere in EVE which is
causing the data synchronizer problem.  The only way to really check
this is with the development system.

377: OZONE, Site 1, Sun 28-Jul-1996 23:14:20 GMT, shut ozone down about 2255Z

• Index

There maay be rain tonight, and LIFT won't run tomorrow early AM, so we've
shut Greg's instrument down.

378: OZONE, Site 1, Mon 29-Jul-1996 14:12:53 GMT, ozone back up

• Index

All readings normal - we use about 5 lb of NO per 9 hours = 13 lb/day, so
with 500 lbs in the cylinder, we should have plenty even with 24 hr/day 
operation through the end of the experiment.

379: HYGRO, Site 2, Mon 29-Jul-1996 15:25:14 GMT, plants cut down near hygro

• Index

I have been a bit worried that the Tddiff plots for the last 2 nights show
station 2 not reversing sign, as it did earlier and as the other stations
are continuing to do.  Yesterday, Erik and I visited the site (while taking
pictures).  We opened up the hygro and cleaned out a few bits of biota,
but it appeared to be okay.  We reinstalled it, but also broke the top couple
of feet of the 4 corn plants which had grown up around the sensor in order
to give it some air flow.  This doesn't seem to have affected the data last
night.

380: SOFTWARE, Site base, Mon 29-Jul-1996 15:32:45 GMT, change to lgnd.loc

I've connected the S+ legend locator function to my fun.array.minmax routine,

381: RAIN, Site all, Mon 29-Jul-1996 21:09:14 GMT, rained last night

It did indeed rain last night - first just as we were leaving at 23Z (drizzle),
and much later (07Z?) while we were in the motel.  Both had thunder and 
lightning.

382: SONIC, Site all, Mon 29-Jul-1996 21:41:44 GMT, sonic tilts

• Index

I've looked at the tilts for the last week, and they are pretty similar
to the two previous weeks I've looked at (see previous comments).  This
is somewhat surprising since the PAM3 sonic has been moved recently.
The final tilt corrections should take the moves into account.

P.S. note that all the sonics spiked a bit in the rain overnight.

Status of the FLATLAND96 data set for 27-29 Jul'96

Saturday was a LIFT intensive, though there were problems with the 2um lidar.
Sunday we took the morning off to see Allerton park (nice wasps).
Monday has been a dull day, with things basically working.

Weather plots
	The atmosphere was pretty conjested over the weekend with numerous
	cloud layers.  Today has been a nice boundary layer day with mostly
	scattered Cu.  Winds have been mostly light.  Temperatures have been
	nice (16-26 C), though lots of humidity (saturated at night).
	With all the clouds, the stability has not been far from neutral.

Dirt: Normal.
      
Winds: Okay.  We still plan to replace the prop on PAM1 when we next drop
	the tower. (We will on Wed. to install Tony's ozone sensor and to
	clean the now-dirty Krypton.)

Temperature: We now have some concerns about the hygro at PAM2 (which seems
	to be about 0.5 C higher than the other sensors), but we saw no
	obvious problem with it yesterday.  Tomorrow is Assman IC day,
	so we'll how it does.

Humidity: Normal.  I'm still bothered that the bph-hygro values aren't
	consistent with my model of the humidity profile, but perhaps
	strange things happen in a canopy.

Pressure: Okay.

Radiation: 
        Solar radiometers: The PAM1 Licor seems to be low, despite being
		cleaned (it didn't look dirty).  It also now has a positive
		bias at night.
        Net radiometers: Okay.

Sonic flags:  Normal - some spikes during rain (last night)
        PAM1: A few on u; continuous on all during rain
        PAM2: Continuous light spiking on u and Tc.
        PAM3: Some u, w, and Tc spikes during rain.

Sonics/fast scalars: 
	speed/dir: Okay
	w: Okay, tilts look similar to earlier periods with "lean" angles
		of 1, 0.5, and 1.8 degrees, respectively.
	second order moments: all normal

Sonics/scalars
	sigma Tc, wTc: Okay.  Still adam-pam differences due to despiking.
        sigma H2O, wrH2O: Okay.  There are adam-pam differences in rh2o:rh2o
		for some reason - did we explain this before?

Overall:
	We haven't had a cosmos crash in 2 days, though we haven't changed
	anything since the previous crash.  Maybe a neighbor with a cellular
	telephone has gone on vacation!

384: EVE, Site 1, Mon 29-Jul-1996 23:13:35 GMT, EVE bug and ozone data comparison

• Index
• Graphics file: plot of bad EVE power data plot of bad EVE power data located in file: log_00384-1.gif
• Graphics file: Adam vs PAM fast O3:O3 covarAdam vs PAM fast O3:O3 covar located in file: log_00384-2.gif

Took a trip to station 1 this morning to try and determine why the
power data was garbage.  Restarted the data collection and the power
data came back.  Reminiscinent of the problems the GAME folks seemed
to be having.  Waited around the station for a while to try and see if
it crashed again.  No such luck.

While at the station was inspired about the potential source of the
problem.  Began digging in the EVE code, and came up with a possible
fix (no way to test it over the network).  Tony will bring out a new
EPROM which may fix the A/D problems.  The problem is essentially a
bug in the A/D software data stream which prevents proper buffering of
data.

Another remaining question on the EVE ozone data collection is whether
the covar data for the ozone is off because of the 2.3 time second
difference right now, or if there is another problem.  There may be a
second problem in the EVE data synchronizer, but it's also possible,
that what looked like a problem in the data synchronizer was caused by
the A/D data flow problem.  Will get a better answer in a couple day's
after the EPROM from Tony is installed.

See the two attached plots.  The first one shows PAM 1 power bad, then
reset to good, then going bad.  The second plot shows O3:O3 covars
between PAM and ASTER.

385: BPH, Site 1, Tue 30-Jul-1996 02:45:06 GMT, problem with aster rh2o

• Index

If I've followed the code correctly, ASTER is using a DEFAULT pressure of
800 mb to compute rh2o from t and rh from the bandpass hygrometer (since
it doesn't have a real pressure in the data stream).  This probably is
the cause of the differences between rh2o:rh2o from pam1 and adam1.

386: RAD, Site all, Tue 30-Jul-1996 02:47:17 GMT, full moon

• Index

I'm out for the first time tonight and notice that the full moon (through
thin cirrus clouds) is reasonably bright - possibly enough to register on
the Licors.  Thus, don't treat values around now as a bias!

387: OZONE, Site 1, Tue 30-Jul-1996 14:30:28 GMT, fast ozone still going

• Index

I've just reloaded the dry ice (and got some more from the Blood Bank).
The sensor ran all last night (even though it rained early this morning).
All readings were normal.

388: SOIL, Site all, Tue 30-Jul-1996 15:41:47 GMT, latest soil densities

• Index

The dry weights of the total samples taken 7/27/96 are:

PAM1:	172.5g => 1.38g/cm3
PAM2:	192.3g => 1.54g/cm3
PAM3:	177.9g => 1.42g/cm3

Matt and I feel more confident that these were true 125cm3 samples, so
I suggest that we go with 1.4 g/cm3 as the density.

389: SOFTWARE, Site base, Tue 30-Jul-1996 17:31:41 GMT, changed sonic_atik.c

• Index

I've changed the atik calibration routine to have the default ambient pressure 
entered as a parameter in prep.config.  I've set this to 990mb for FLATLAND.

I just "make"d prep, covar, xcockpit, and xstrip and restarted covar on
cosmos.

Gordon: I tried another way to do this at first, but the variable
"p_baro_share" was being written to by some routine which I couldn't
find, so I just overwrote the value in sonic_atik.  You may want to
look at this further.

  Set delay for   ozone covars to 0.3 sec.  No overall 2 sec delay any
 more.

• Index

Visit to all three sites this afternoon.  Same procedures preformed at
all stations except 1 (which is noted below.

Offloaded data for jd 207--212.

Did Assman IC

Did rain gauge IC

Also on station 1: took site photos and loaded new configuration.  The
new configuration adds error data points for the three analog
processes (ozone, Tsurface, and power).  These parameters are mostly
for software testing and debugging.

 Coments: Several things:  installed new EPROM and new config.  Swapped
 prop vane with RMY version--but old one seemed to be OK (slightly bent
 prop shaft).  Installed Tony's "pipe bomb" ozone sensor (through adam
 only).

395: ADAM/NETWORK, Site 1, Thu 01-Aug-1996 00:55:04 GMT, added Tony's ozone channels

• Index

We've just added Tony's ozone instrument (conc.O3.secl.3m) and turned on
an additional channel for the CU instrument if it ever comes.  I just
rebooted cosmos to make the change.  (mxreset killed it, so the key was
necessary).

Note that the tower was down for about 2 hours (5pm to 7pm local) while
we did that.  This was mostly due to prop cabling problems - see next
comment.

396: PROP, Site 1, Thu 01-Aug-1996 00:57:28 GMT, RMYoung prop installed

• Index

Since we have been suspicious of the bearings on the prop at site 1,
we replaced it with our only spare - the RMYoung prop.  This required
some station software changes by Matt.

Matt found that there were cabling and direction alignment problems
with this new prop which he fixed on site.  We will check the direction
tomorrow, since the alignment was not precisely done.

397: UNIX, Site ASTER, Thu 01-Aug-1996 14:58:47 GMT, aster rebooted yesterday

• Index

We forgot to note that we rebooted aster itself yesterday (and thus
also cosmos) because the serial port was "locked" and wouldn't let
the dp process connect to the outside world over the modem.
(We had tried restarting dp, but even kermit couldn't connect to the
port.)  Rebooting fixed the problem.

398: LOG, Site all, Thu 01-Aug-1996 20:43:41 GMT, Site visits to get soil samples and measure crop height

• Index

Went to stations 3, 2, and 1.  Got soil samples and crop height measurements.

See entry 39 for crop height data.

• Index

On Wed, 31 Jul 96 the SECLOD was installed at PAM 1.
The sensor was strapped to the sonic boom just behind the
level of the Krypton hydrometer. The cables were strung
and because of the lengths of the cables the power supply
had to be strapped to the tower upright.
The sensor output was very very low but it was left 
overnight to precondition. It was realized that the cables were
attached backwards but the sensor could not by fixed until the 
evening of Thurs 1 Aug as an intensive observation period was occuring.
On the morning of Fri 2 Aug the SECLOD signal was healthy and 
compared in structure to the Kok machine fast ozone sensor.

SECLOD response fell off at 1 Hz and the Kok machine exhibited 
white noise commencing at several Hz.

409: EVE, Site 1, Sat 03-Aug-1996 19:10:38 GMT, A/D problem and fast ozone data collection

• Index

The A/D problem on EVE is still not solved.  The problem occurs on a
heavily loaded system (station 1 with the Ozone).  Current incantation
results in the loss of the fast O3 data stream.  Once the O3 data is
gone, the data collection must be restarted to get it back. 

On the hardware side, an anti-aliasing filter is needed for better A/D
covar data.  W:O3 is ok, but O3:O3 data shows noise from the fast
ozone sensor.  

Station 1 visit this morning to try and determine cause of A/D
problem.  Unplugged ATI for a few minutes to no avail.

Ingest was rebuilt, installed and restarted.  The matrix code
was rebuilt.  Since the adam was conveniently crashing every hour or so
I just let it load the new code and spawn a new ingest on its next reboot,
which happened at 21:36 on aug 5th.

GPS readings for the base station and station 1 were taken yesterday but had to
be repeated today due to faulty programing on the base station receiver.
thought I had it set up to take 24 hrs of data through 18:30 today, but when
I went to download, I found only 10 min from yesterday just before the program 
was to begin! readings must be concurrent so station 1 was repeated also and
it looks like everything was successful.
quality control checks are not possible yet due to the PC being minus a
math coprocessor. I will check with UNAVCO tommorrow to see if anything else
can be done.
GPS antenna height was transfered to pam station through the use of the
transit.


center of lens of transit is 19 cm above choke ring ( the altitude that the GPS
data will provide to us ). the height of the transfer via transit to the pam
station #1 was 73 cm above the pressure port, and 205.8 cm above the bottom of
the electronics box.
therefore, GPS derived altitude is 186.8 cm above bottom of box and 54 cm above
pressure port.
(by the way, a measurement was taken from the choke ring to the surface and from
the surface to the bottom of the electronics box, as an alternate method of 
transfering antenna height to the pam station, and it was off by a whopping
4.6 cm! seems like the transit is a lot of effort when the GPS accuracy is
only good to within a half a meter!)

461: LOG, Site base, Sun 18-Aug-1996 17:15:19 GMT, GPS readings for Pam and ISS completed

• Index

GPS readings for the base station and Pam 1-3, and both ISS trailers are
now completed, along with quality checks.
results are as follows:

GPS antenna height was transfered to pam station through the use of the
transit.


PamIII station 1:

	Gps derived altitude - 186.8 cm = height of elctronic box bottom
	Gps derived altitude - 54.0 cm = height of external pressure port

PamIII station 2:

	Gps derived altitude - 158.0 cm = height of electronic box bottom
	Gps derived altitude - 28.0 cm = height of external pressure port

PamIII station 3:

	Gps derived altitude - 40.6 cm = height of electronics box bottom
	Gps derived altitude + 91.6 cm = height of external pressure port

Monticello ISS (ISS #1)

	Gps derived altitude - 24.0 cm = height of port on pressure sensor
	Gps derived altitude + 59.0 cm = height of external pressure port

Senica ISS (ISS #3)

	Gps derived altitude - 5.0 cm = height of port on pressure sensor
	Gps derived altitude + 38.4 cm = height of extrnal pressure port
	Gps derived altitude - 62.2 cm = height of balloon launching platform

all measurements were also done using a simple tape measure as opposed to the
transit, and the worst case error was found to be 13.0 cm, best case error
was 2.9 cm, and avg. was 7.1 cm.
	not bad for an accuarcy of +- 50 cm from Gps

	the actual Gps antenna heights will be processed from the data in
Boulder with the apropriate software provided by UNAVCO.
Quality checks were completed in the Pam base for all the data, and all
surveys looked quite good.

486: OZONE, Site 1, Wed 11-Sep-1996 20:25:23 GMT, Calibration and offsets for Kokod fast ozone detector

• Index

During the first two weeks of September the data from:
           Tecod, the ThermoElectron ozone detector
           Kokod, the gas-phase chemiluminescese ozone detector 
were examined. 

Tecod was operating continuously from <22 Jul 96 until 22 Aug 96.
Until 5 Aug 96 the airconditioner temperature transients
induced periodic noise spikes. After that date the air conditioner was
disabled.

Kokod was activated 22 Jul 96 and operated until 22 Aug 96
The first few days were not reliable nor continuous and thegood data
set begins 15:00 GMT 25 Jul 96.

The combined Tecod and Kokod data was examined using 
	   "fun.ozone.cal.plot()"
to select periods ofgood and bad data.

The data was then processed using
	    "fun.ozone.scatter.plot()"
to generate offset and calibration factors for good data periods.
NB all dates and time are based on GMT

487: SONIC, Site all, Tue 17-Sep-1996 22:35:19 GMT, Averaging periods, angles and heights for the PAM1, PAM2 and PAM3 sonics

• Index

The sonic data for the three sites were examined in order to ascertain
the time intervals over which to integrate data to define the pitch.

Three primary sources of information were considered:
    project long plots of fun.var.plot("alev.atik.3m.pam1/2/3")
    project long plots of tilt <- fun.sonic.tilt.summary("atik.3m.pam1/2/3")
       This function plotted w offset, lean, and azimuth as three panels
    logbook. The logbook was  search to account for specific details indicated
       by features exhibited by the plots.

The sonic data for each of the three sites were separated into several separate
intervals, following the analysis given in Logbook entry #287.
The tilt program:
              fun.sonic.tilt.plot("atik.3m.pam1/2/3")
was then operated upon each sonic data period and the coefficients calculated.

Derived Barometer Elevations:
---------------------------------------------------------------
Are provided given the GPS data Kurt obtained and Unavco post
processed.  The Unavco readings are adjusted by subtracting the 
measured relative antenna heights that Kurt reported in his logbook
message #461. 

NOTE1: the full text provided by Unavco is included at the bottom of
	this message.  I don't recommend reading it.
NOTE2: I don't know what the station 'PAM1-PAM1' was but i suspect
	these numbers came from a short file obtained on Kurt's first
	attempt which only had 11 minutes of data.    The details in
	the Unavco printout below indicate that PAM1-FLATLAND coincides
	with the measurement times when Kurt did the 'real' survey on
	the 11th, that he recorded in the log and on hand written paper.
