| Graphic: | T1.5m OU-NCAR vs V
July 15
Wx: Clear, a bit hazy. Slightly cooler than usual. Light winds from E.
Base: Still floundering with dat code for soil. Found that the constants
we are using for the OU moisture aren't working (giving NAs). Jerry is
checking.
Last night started work processing OU Bowen ratio measurements, ultimately
to yield w'h2o'.prfl. Got pretty far, but saw a sign reversal problem.
Jerry will check on this also.
Also created dat.azimuth which reads a file of sonic boom angles. dat.dir
still isn't picking this information up properly.
T/RH: No T/RH reporting problems since I replaced the HC11 board.
The NCAR sensors do have large (0.5 C) radiation errors during winds with
a northerly component. See the graph of T NCAR-OU vs. north wind component
attached to this entry. Both 1.5m and 9m show this trend.
P: ok. I've created a dat.P with my temperature correction so that we
can check if the temperature dependence is constant. It gets the magnitude
of the pressure variation better, though there still is a large phase shift
between the NCAR and OU signals.
Wind: ok. Spd profile looks good. NCAR speeds are greater than OU.
Radiation: pretty good.
(T,G,M)soil: ok. See Tony's extensive comments elsewhere in this volume.
Sonics: Yesterday was a big day! All sonics are now operating, though
we need to zero the UWs and work on their calibration routine. That's
the first task for today.
Krypton: ok. OU cleaned theirs 2 days ago, so the means are now closer and
the variance is smaller (though there still appears to be a noise floor
at night.) The fluxes never were too bad between their system and ours.
fastT: ok. Variance from OU's is somewhat higher than ours, which could
be either (or both) spatial filtering of our signal or noise on theirs.
bph: ok. Look reasonable - lower variance than fast sensors, but same
shape.
Rain: No rain

118: SONICS, Site , Tue 14-Jul-1998 11:55:04 CDT, ati.9m boom angle shot
Tony and I just shot the boom angle for the 9m ATI with the theodolite.
His reading was: 3 degrees 16' 40"
My reading was: 3 degrees 14' 08"
I think both readings were about of equal weight, so I would average these
to 3 degrees 15'.
This was shooting the back "U" transducer through the arm supporting the
front "U" transducer (and probably the top "W"). I noticed that the
4.5m ATI was facing more easterly, i.e. an angle more like 1 degree?
117: SOIL_SENSORS, Site NCAR, Tue 14-Jul-1998 10:24:09 CDT, Soil core, pit and clod samples taken
At 09:00 CDT soil samples were taken from the area north of the rad stand.
A soil core was made and the top 0-6cm taken for a single sample.
A soil pit was dug ~12cm deep. A ~ 500g sample of the top 0-6cm portion
of the dressed edge was taken. Three soil moisture aliquots were made.
Two 12 cm deep chunks of the surface soil were extracted. On the bench three
rectangular prism clods were sawed from the chunk for soil moisture and
bulk density determination.
see #40
116: SONICS, Site NCAR, Tue 14-Jul-1998 09:11:46 CDT, atm.9m remounted
We've RTV'd the ati K-probe back together. I also did a laboratory (trailer)
zero calibration on all 3 paths. It found biases of about 1 cm/s and path-
lengths of about 14.6 cm for all paths.
The boom is drooping a bit, just due to the weight. I've done as much as
I can with the yoke - there is a bit of play in the square part of the yoke.
We could try shimming. For the moment, I've just left the droop in, assuming
that it can be removed later by tilt.sonic.
We still need to shoot the new boom angle. I wouldn't expect it to have
changed much.
115: KRYPTONS, Site OKMN, Mon 13-Jul-1998 16:34:15 CDT, Cleaned OKMN Krypton Hygrometer
At 16:30ish we cleaned the window of the Mesonet Krypton hyrgrometer using a
cotton swab and distilled water. The window was also dried using a swab.
There was small black chips on the cleaning swab.
The previous voltage was approx. 35 mV...we will watch it to see how it varies.
114: SONICS, Site NCAR, Mon 13-Jul-1998 15:49:15 CDT, second K-probe back at 1m
We installed the replacement U2 transducer in the ati K-probe and have
had it running at 1m on the UW tower for about an hour. We'll continue
to run it for a while to decide if it is working well enough to mount at 9m.
When we do, we will have to:
1. zero it
2. feed a bit more cable up the tower
3. shoot the boom angle.
113: HYGRO, Site NCAR, Mon 13-Jul-1998 12:05:46 CDT, THR 1.5 HC11 swapped
The T/RH at 1.5m was dead again this morning, having died at ~06:05 UTC.
I decided to swap the HC11 boards with the spare we have. Of course,
it also was necessary to swap the coefficients. Before the swap, I saved
the coefficients as:
$ASTER/projects/OASIS98/doc/trh1.doc & trh3.doc.
Then, I reprogramed TRH003 with the coefficients from TRH001 (using COFL).
NOTE: I DID NOT CHANGE THE SERIAL NUMBERS, SO THE SERIAL NUMBERS ARE OF
THE HC11 AND NOT THE SENSOR.
I loaded sensor #1's coefficients into CPU #3
I pulled the old sensor with CPU #1 from the tower.
I swapped brains in the trailer.
I reinstalled the sensor with CPU #3.
I loaded sensor #3's coefficients back into CPU #1 (the spare), just to be
safe.
Thus, CPU #3 should be debugged in the lab, if possible.

Sunday, July 12
Wx: Standard OASIS98 day. Cloudless this morning, Looks like it will get
hot again.
Base: Steve has made a color-coded idraw of the dat objects. He talked
to Gordon and discussed Neechee(or something like that). A scheme to
apportion the soil Ts, G, and Ms was devised. I will run the soil energy
budgets today and see whether the scheme is good.
T/RH: Again, TRH at 1.5m was dead this morning. It will be replaced with the
spare.
T and RH profiles look good
P: ok.
Wind: ok. Spd profile looks good
Radiation: ok.
(T,G,M)soil: ok. Gsoil.1 now fitting in with the rest.
Gsoil, 1, 2, 3 scatter, day-time max +_ 15Wm-2, night-time min +_5 Wm-2
Tsoil, 3 is 45-60 min ahead of 1 and 2 in its maxima and minima.
Steve and Gordon have devized a scheme to apportion Ts, Gs and Ms.
Msoil1 data for plotting interupted after the scheme started.
Doing another intercomparison between corer and digging
Sonics: Still waiting for UPS to deliver the new transducer.
Krypton: ok! .
fastT: ok.
bph: ok. mr.bph variance agrees pretty well with h2o variance!
Rain: No rain

111: SOIL_SENSORS, Site NCAR, Sun 12-Jul-1998 10:06:16 CDT, Soil core and trench samples Trime
At 09:00 both a soil core sample and a soil trench sample were taken
in the area north of the roped-off radiometer stand.
Soil core, 0-6cm, fresh wt = 184.0g
Soil trench, 0-6cm, fresh wts CI = 19.3g CII = 21.2g CIII = 22.0g
At 10:00 the Trime probes were inserted Readings:
Moisture Vol% 6.7% 6.8% 6.9%
TDR level 56.0 56.0 56.0
Left probes in the ground to see if the readings will change with time,
At 10:35
Moisture Vol% 7.2% 7.1% 7.1%
TDR level 54 55 55
At 11:00
Moisture Vol% 7.1% 7.1% 7.1%
TDR level 54.0 55 55
The difference between the fist set of readings and all subsequent readings
may also have been due to the heating of the Trime electronics, as the sun
caused the box to heat considerably.

Sunday, July 12
[We're planning to only work this morning, since the OU people also won't
be here today (Jerry and Chris were here yesterday). We had fun last night
finding flaws in "Armagedon" (sp?).]
Wx: Sct Cu now - could be another warm one. Winds still southerly yesterday,
but generally pretty light. Currently they are from the NE.
Base: I've just bkfiles_kill'ed, so we're now down to 21%.
I also took several pictures with the digital camera yesterday of the sensors
and created a skeletal WWW site on stout with them.
I've made a color-coded idraw of the dat objects. We still have some
configurations to play with - I'm waiting to talk to Gordon to discuss
philosophy.
T/RH: TRH at 1.5m was dead this morning. See previous logbook entry.
We're not reading RH from OKMN. Perhaps we should.
P: ok.
Wind: ok. Why aren't the OU data plotted when asking for "Spd", but are
when asking for "Spd.2m"?
Radiation: ok. There was a full moon 2 nights ago, but I don't think
we can measure it! (Tony says it is 10^-6 of sunlight, or 1 mW/m2.)
(T,G,M)soil: ok. Gsoil.1 now fits in with the rest.
Tsoil.1 NCAR agrees with Tsoil.1 OU and Tsoil.2 NCAR agrees with Tsoil.2 OU,
but not with Tsoil.1. This has to be coincidence, since the sites are
not colocated.
Sonics: UPS didn't deliver the new transducer for ati.9m because they needed
a signature and didn't get one from the front desk!@$#! I guess we'll have
to wait until Monday.
ati.4.5m and csat.4.5m have worked pretty well, with only a few spikes
appearing on cockpit. Statistics look reasonable when plotted as a time
series - scatterplots may show differences.
One of the UWs was sent to ATI to get an EPROM upgrade (I think). Hopefully,
this will allow us to use it for a 20cm path.
Krypton: ok! Suggested that the OK sensor to be cleaned, since h2o'h2o'
looks terrible. Their voltage channel shows 30 V, which obviously is wrong.
I could believe 30 mV, which is too small for normal operation. However,
the fluxes don't look too bad.
fastT: ok.
bph: ok. mr.bph variance agrees pretty well with h2o variance!
Rain: No rain
Comments:
109: HYGRO, Site NCAR, Sun 12-Jul-1998 09:12:14 CDT, trh at 1.5m restarted
The TRH at 1.5m died at 07:54 GMT last night. We have no idea why.
rserial didn't respond to wake it up; however the fan was running when
we went out to check on it (therefore it had power).
Cycling power brought it back to life.
(What good is COP if it allows this to happen?)

Saturday, July 11
Wx:Yesterday was hot, similar to the weather for the whole of the week. In the
afternoon grey cumulus developed but there was no rain. The remnats of the soil
dampness was gone. This morning is partially overcast.
Base: Yesterday cocklebur was down when we arrived. It was brought up but
low-level problems persisted, slow response, difficulty in finding data.
Steve spent a portion of the afternoon re-ordering the access to soil
parameters. He has cleaned up the system, killing processes. Sent all marigold
and some ragwort files to NCAR.
T/RH: Profiles look OK. Note: after the rain the gradients of RH increased
P: See logbook # 103.
Wind: Profiles of Dir and Spd look OK. .
Radiation: ok The Rsw negative fluxes of ~ 3 - 5 Wm-2 during the night-time
are, apparently, a real instrumentation response. The sensor exports a small
energy flux throughout the night. See logbook # 85.
(T,G,M)soil: Gsoil.1 is an outlier with too small a magnitude, but the
difference is closing.
.
Sonics: 9m ATI was been brought into trailer. One of the u transducers was
temperature sensitive, generating a weak signal. It was removed and ATI will
FEDEX a replacement. A method for the re-stringing the transducer coax
was developed. Hopefully we should be able to make a field replacement
of the transducer.
The UWs are to be sent to ATI
Krypton: ok! Asked for the OK sensor to be cleaned
fastT: ok.
bph: ok.
Rain: No rain
Comments:
ADAM temperatures top out at ~ 35 degreeC
107: LOG, Site , Fri 10-Jul-1998 17:35:09 CDT, Daily status (abbreviated)
We spent today figuring out how to repair the 9m ATI. Herb is sending
out a new transducer tomorrow, and we'll try to replace it in the array.
We also worked a bit on software, trying to get Gsfc running, along with
some nuisance software issues resolved (mostly failed).
check_aster has been normal, except for 2 nc_server processes (we killed
one).
cockpits have been okay.
Otherwise, we didn't do any QC checks today.
backup was done. I'll kill the files when I return tonight (we're now at 93%)
to allow me to try to FTP them to Boulder. The data rate was 14 K/s earlier
today, which was a bit slow for this much data.
106: SOIL_SENSORS, Site NCAR, Fri 10-Jul-1998 10:21:38 CDT, Moist layer in soil
The major thunderstorm at 03:30 dumped heavy rain, leaving puddles on the dirt
road to the site. For the next three days test pits were dug at ~ 09:30
8 July: top 2.5cm of soil noticeably dark, below still dry.
9 July: top 3.5cm of soil dark
10 July: soil apparently uniform to inspection
Gravimetric soil moisture meaurements were made on 7 July, prior to the rain,
and on 8 July, after the rain measurements were made of 0-3cm and 3-6cm.

105: SONICS, Site , Thu 09-Jul-1998 17:29:44 CDT, csat spatial averaging
- Previous -

Index
| Graphic: | uw spatial averaging
Tom has e-mailed me the response for spatial averaging for one path from
Kaimal's 1968 paper, and I have the data for my model of the spatial averaging
for the UW. I have added a plot of these to this entry. Generally, the
response with 3 paths at 60 degrees from a sonic with a 10 cm path (the
CSAT) to W is about the same as a single vertical path with a 15 cm pathlength.
Thus, spatial averaging does not explain the differences we are seeing between
statistics from the CSAT and ATI.
- 104: SONICS, Site NCAR, Thu 09-Jul-1998 12:05:16 CDT, 9m ATI taken down
To allow us to check why the 9m ATI is spiking on U, I've climbed the tower
and taken the sonic head down. (The Krypton is still mounted to the boom
at 9m). Note that I had to disconnect the yoke in order to give the cables
enough play to allow me to pull the head out of the boom, so TILT CORRECTIONS
WILL NEED TO BREAK THE FIT AT THIS TIME.
The head is now reconnected and running on channel 201, but is physically
at 1m on the UW test tower (which has no other sonic running on it yet).
Already the U channel appears to be spiking, so this is a good test
configuration.
We're going to lunch now. Assuming that it is still bad after lunch, I'll
try looking at the signals on the scope.
----------------------------------
5:30 PM
It appears that the u signal is weak, I think going from u2 -> u1 (the
4th of 6 transmissions). I'm going to try to get another transducer sent
here as a replacement. Note that this sonic has been off and on all
day as I fiddled with it - all at 1m on the UW tower. I've taken it off
completely for the night, since it is not weather tight. I'll put it
back up to 9m tomorrow.
- 103: BAROMETER, Site NCAR, Thu 09-Jul-1998 10:46:42 CDT, pressure temperature compensation
I've been playing with the temperature error in our pressure data. I get
a reasonable fit with:
pNCAR = pOU - 0.2 (T1.5-27)
The fit has somewhat less scatter if I include a 10-20 min delay between
the pressures and temperature.

Thursday, July 9
[Sorry for missing a few days - the need to do a daily status got lost
in the transition from Tom to me. See other entries for significant events.]
Wx: Broken Cu, winds light and westerly (at the moment)
Yesterday's winds also were quite variable. The ground also is moister (and
slightly greener) following the rain early yesterday morning.
Base: ok. The adams rebooted in the electrical storm 2 nights ago, but
came up by themselves. The RF network modem was swapped out by Stan 2 days
ago since it was too powerful (500, rather than 100 mW). It then died during
the electrical storm, but came back after cycling power and waiting about
1/2 hour.
T/RH: Profiles still are a bit strange. See logbook #94 for some details
on playing with RH and T biases.
P: Still see heating effect. We should try radiation shielding today.
Wind: Speeds ok. Flipping the vane at 2m 2 days ago helped make the directions
consistent. Flipping the vane at 6.5m appears not to have helped.
Radiation: ok. Tony and Tom have been looking into Rsw negative fluxes of
~ 3 - 5 Wm-2 during the night-time.
(T,G,M)soil: Tony dug up and replanted T probe and G plate site #1 2 days ago,
since Gsoil.1 was an outlier (too large magnitude).
Fortunately, it rained about 9 hours later
to help "set" these sensors. However, Gsoil.1 is now an outlier with too
small a magnitude! Tony will keep on looking at this.
Sonics: 9m ATI U is spiking heavily during the heat of the day and improves
at night. V & W are behaving well. Cooling the boom (and thus electronics)
with a wet towel 2 days ago may have helped somewhat, but didn't eliminate
the problem. We've also seen spikes on 4.5m ATI, though not as bad.
The OU CSAT has given a few spikes, but not as many as the ATIs.
The UWs are now built, but not working. (Both were operated for a few minutes
yesterday giving -99.99.) I'm trying to isolate this problem.
Krypton: ok! (even though it rained 2 days ago) I cleaned both of ours
2 days ago, which changed the offset by about 10 g/m3, but the gains appear
to be the same. Variance of 9m is lower than 4.5m (as expected) and also
larger after the rain (as expected). Variance from the OU sensor is too
large - I wonder if this is noise? (And/or if it should be cleaned?)
fastT: ok! (worked through the rain) Variance from ours is still less than
from the OU CSI thermocouple.
bph: ok.
Rain: ok. There were 2 events in yesterday morning's rain. The first, both
OU and NCAR show about 6 mm of rain. The second OU shows 89 and NCAR 64 mm.
There also is a time shift (NCAR late by 5min), which apparently has been
known.

That is, to a simple approximation, if the 5cm depth of soil is taken to be
heated uniformly during the day, and cooled uniformly during the night,
the storage term corresponds to a energy influx/outflux of ~ +_30 W.m-2

At 10:00 7 July a soil core was taken north of the roped-off area
Fresh wt of top 6cm = 173.9g
Placed in oven for two day bake.
During the night, at ~03:00, 8 July, it rained. At 08:30 the morning of 8 July
a test hole was dug. The moisture had penetrated 2-3cm. Below was still dry.
At 09:00 8 July a soil core was taken north of the roped-off area.
Fresh wt of 0 - 3cm = 83.3g
Fresh wt of 3 - 6cm = 88.6g
Placed in oven for two day bake.
At 09:30 a Trime measurement was made.
Moisture = 10.7 %, TDR level = 46.0
Note only the top few cm are moist.
- 98: LOG, Site NCAR, Wed 08-Jul-1998 08:09:57 CDT, lots of rain last night
There was a thunderstorm about 3:30 last night (it woke us up in the motel!
There are some puddles around the site.
The OU network went down, so we are unable to look at OU data. Stan is
working on it.
The ADAMS apparently rebooted themselves during the storm - probably due
to lightning. I didn't know they would do that!
All sensors appeared to have survived:
1. NCAR Fast t works and shows a 5 degree drop, along with the slow Ts.
2. NCAR kryptons got wet, but dried in 1-2 hours. Perhaps their offset
(difference from hygrothermometers) has changed by 0.5 g/m3).
[Note that their offset is now negative, which may indicate that we
are using the "scaled" calibration.]
3. Soil sensors record the moistening and increased cold flux into the soil
as expected. The soil Ts show a cold pulse during the rain, and then
settling back to the general nighttime cooling trend. All this is normal.
Tony is very glad that he [had the foresight to] reinstalled the sensors
at site #1 just before this wetting event. Also note that this site did
not record the most moistening, so he didn't disturb the soil too much.
- 97: SOIL_SENSORS, Site NCAR, Tue 07-Jul-1998 16:36:44 CDT, Re-planted Gsoil and Tsoil NCAR1
Examination of Gsoil for the past two week's data indicated that the
NCAR1 Gsoil values were markedly out of line with all the other G's.
To a lesser extent Tsoil T was also somewhat different.
At 16:15 CDT I dug out the two probes and reinstalled them.
I did not disturb the Msoil probe, although its output too was somewhat
out of line with the other moisture probes.
- 96: PROPS, Site NCAR, Tue 07-Jul-1998 16:28:24 CDT, flipped 6.5m prop vane
Since flipping the 2m vane worked so well, I've just flipped the 6.5m prop
also.
- 95: SONICS, Site NCAR, Tue 07-Jul-1998 14:14:13 CDT, wet towel on sonic
In an attempt to figure out why the 9m ati is spiking, I wrapped the boom
with a wet towel about 1400 CDT. (We hoped that the electronics would be
cooled.) This did not affect the spiking, but probably disturbed the
krypton humidity measurement. I'll remove it in another 15 min. or so.
Towel was removed about 15:05. It was still damp. I also used a finger
to wipe a bit of dust off of both U transducers. I doubt that any of this
made any difference.
- 94: HYGRO, Site NCAR, Tue 07-Jul-1998 10:59:13 CDT, fine adjustments to RHs
I've just played with the last 3 days of data and find that the ordering of
the RH profiles is improved if 0.6% is added to RH.4.5m and 0.1% is
subtracted from RH.6.5m and 0.2 is added to RH.1.5m.
Also, the T profile is slightly better by subtracting 0.04C from T.6.5m.

just-to-be-created WWW page on OASIS.
- 92: KRYPTONS, Site NCAR, Tue 07-Jul-1998 10:23:07 CDT, Cleaned NCAR krypton hygrometers
Steve cleaned the NCAR krypton hygrometer windows with distilled water

This changed the voltages from 0.02 to 0.15 for ch 100 and from 0.1 to 0.7
for ch 101, which isn't a huge change, but somewhat better.
- 91: SOIL_SENSORS, Site NCAR, Tue 07-Jul-1998 09:23:37 CDT, Bulk Density of soil
On Sunday, 5 July a block of soil was dug up from the area immediately to
the north of the roped-off area around the radiation stand. It was noted that
the top several cm were more friable than the deeper soil.
In the trailer the block was whittled down to give roughly rectangular
prisms. One was formed from the top 3 cm and the other from the top 6 cm.
The blocks wereput in Al pans and baked for two days.
On Tuesday, 7 July the blocks were removed from the oven and weighed.
They were then impregnated with wax and their volumes determined by immersion
in water in a graduated vessel.
Top 3cm: Dry mass = 59.2g, Volume = 35cm3, Bulk density = 1.69 g cm-3
Top 6cm: Dry mass = 120.3g, Volume = 75cm3, Bulk density = 1.60 g cm-3
- 90: PROPS, Site NCAR, Tue 07-Jul-1998 09:13:17 CDT, flipped vane on 2m
I just flipped the vane on the 2m prop (the RM Young lettering is now
upside down) to test if the 2 degree difference in wind direction is due
to some asymmetry in the vane. I could imagine that the vane was slightly
bent (I off to the left, when viewed upside down from the hub).
We'll look at today's data to see if there was an effect. Tom points out
that the 1m could be bent instead, so we can try it tomorrow.

- 88: RADIATION, Site All, Mon 06-Jul-1998 09:36:37 CDT, Peculiar lw.in radiometer response
There is a discrepancy between the responses of the uplooking NCAR lw radiometer
and the uplooking OKMN lw radiometer. This is well illustrared on Jul 3, a
clear, cloud-free day.
The Rlw.in plot shows an earlier and higher peak for the OKMN than for the NCAR.
Note that the Rlw.out plots show agreement between OKMN and NCAR.
The Tdome and Tcase plots showed that the OKMN were 1-2 degreeC warmer than
NCAR, but no structure which could lead, in compensation correction, or
dome/case correction to the structural difference showed in Rlw.in.Note that
the difference of 1-2 degreeC is significant.
The Rpile.in plot shows the strong feature.Several aspects were considered:
- Ventilation: the OKMN is ventilated differently than the NCAR. However
the dome and case temperatures plots do not show the strong
feature.
- Level: to account for the phase shift a tilt of ~11 degrees would be needed
- Photodegradation: the Si vacuum deposited coating inside the dome is
susceptable to uv degradation. This could allow a non-
uniform illumination of the photopile. What history
does this radiometer have?

- 85: RADIATION, Site NCAR, Sat 04-Jul-1998 13:46:49 CDT, Night-time response of Eppley short wave radiometers
It was noted that immediatedly after sunset the response of the incoming
and the outgoing short wave Eppley radiometers indicated negative short wave
radiation fluxes.
To test whether this was an offset due to the Campbell electronics, the input
from the two radiometers were sucessively shorted, with a jumper between pin 1
and pin 2. In each case to apparent output decreased to +_ 0.078 Wm-2
This value of ~ +_ 0.1 Wm-2 is the data system uncertainty.
It is surmised that the indicated negative radiation flux is due to thermal
effects within the Eppley radiometers. The inside junction of the thermopile
views the warm inside of the radiometer case while the other junction
views the inside of the dome. The thermopile is sensitive to long wave
radiation and so responds to the flux of long wave radiation from the warm
interior of the sensor to the cooler dome.
The artifact is most severe for the first hour after sunset when it corresponds
to ~ 5 Wm-2. Then,throughout the rest of the night, the artifact maintains a
value of ~ 2-3 Wm-2.
As the artifact is common to both upward facing and downward facing radiometers,
the effect should almost cancel when the net radiation flux is calculated.
NOTE The K&Z short wave radiometers responds in a similar fashion
We suspect that the OKMN short wave radiometer data is forced, by software,
to yield 0.00 Wm -2, whenever its output goes negative.

of a small offset in tc (tc' statistics were identical), likely caused

sensors on the ATIs. According to ATI, the transfer
function is: x degrees = counts * 1.5 / 1024
"sonic_atik.c" was changed to use this as the default
gain setting. If you need to change this to a different
value it can be done in "prep.config". The function
"sonic_atik.c" can accept 5 input parameters. Parameter
5 is used for this gain term.
NOTE: you must provide a value for parameter 4.
example: c=sonic_atik("ati.9m.OASIS98,1e-5,2.5,"flag",0,.1)
where .1 is the gain value
The "DID" names for the level sensors were changed from
"alev" and "blev" to "lev.u" and "lev.v", respectfully.

From 14:00 to 16:30 (local) I was playing with the
levels of the ATI. I started with the 9m. This required
adjustmments on the chain links and turnbuckles on the
south guywires. Once this was completed, the 4.5m was
adjusted using some panduit ties, a radiator clamp, and
some choice words! I talked to ATI about the calibration
function for the sensors. It is different from the old
units. Therefore the calibration routine for the sonics
will need to be modified.
The new transfer function is:
degrees = counts * 1.5/1024
According to ATI the sensor range is +-4 degrees over a
range of +-2048. However it is not that linear over the
full range. They recommended using the smaller range.
At this time, we are not sure their function is correct.
Tom is doing some number crunching to try to confirm this.

Gordon,
I think we finally have a handle on the data we will be sending to the ASTER facility. There are 4 stations near the ASTER setup from which data needs to be ingested.
These stations and data table names are:
Station Data Table
NORM AST05F
NBRD AST05D and AST05E (had to be split up due to record length)
NCOM NET05A
NRAD NRAD5LA
The current plan is to write these tables to one file every 15 minutes and make that file available to the ASTER facility via ftp. The file name should be of the format:
YYMMDDhhmm.ast
This file should be available at approximately 8, 23, 38, and 53 minutes after the hour and will contain data from the previous 15 minutes.
Sample files are available via FTP from:
129.15.195.51
Username: aster
Password: Aster (case sensitive)

- 50: SONICS, Site , Mon 29-Jun-1998 10:50:28 CDT, Effect of sonic leveling errors on eddy fluxes
Let 'a' be the angle of the u axis above horizontal. Then
u_r = u*cos(a) + w*sin(a)
w_r = -u*sin(a) + w*cos(a)
uw_r = (ww-uu)*sin(a)*cos(a) + uw*(cos(a)^2 - sin(a)^2)
(u*_r)^2 = (u*)^2*[1 + (uu-ww)/(u*)^2*sin(a)], cos(a) ~ 1, sin(a)^2 ~ 0
From data, (uu-ww)/(u*)^2 has a value around +5, so a = 1 deg gives an
error in u* of about 4%. Assuming w = 0, a = atan(-w_r/u_r) give an angle
of 1.64 deg for the ATI sonic and an error in u* of about 7%. For the
CSAT sonic, a = -0.63 deg, for a u* error of -3% and thus
(u*_r).ATI = 1.1*(u*_r).CSAT
The data show (u*_r).ATI = 1.14*(u*_r).CSAT
wtc_r = -utc*sin(a) + wtc*cos(a)
wtc_r = wtc*[1 - utc/wtc*sin(a)]
From data, utc/wtc has a value around -2, so a = 1 deg give an error
in w'tc' of about 3.5%. Thus the error in w'tc' for the ATI is about
6% and the error for the CSAT is about 2%, so that
wtc_r.ATI = 1.08*wtc_r.CSAT
the data show wtc_r.ATI = 1.13*wtc_r.CSAT
- 49: SONICS, Site , Mon 29-Jun-1998 10:26:46 CDT, Releveled NCAR 4.5m sonic
Plots of w versus u and v give the following for the three sonics:
atan(w/u) w (m/s) atan(w/v) w (m/s)
ATI 4.5m -1.64 deg 0.03 -0.70 deg -0.09
ATI 9m -1.29 deg 0.02 -0.15 deg 0.08
CSAT 4.5m 0.63 deg 0.04 -0.04 deg -0.08
We releveled the NCAR 4.5m sonic between 9:30 and 11:00 this morning,
using a bubble level. The u axis is level, but the v axis is still
high to the west.
Steve checked the u axis with the theodolite, looking east along the
boom, and it looks good.
I looked at the bubble on the OKMN CSAT and it is right on center.
- 48: PROPS, Site , Sun 28-Jun-1998 12:00:36 CDT, New Prop angles
I shot the props again today. Below are the results.
There is not much difference from the first time except
for the 2m prop which we moved. The new angle for the
2m prop was entered into the eeprom at ~11:50 local.
The 6.5m prop has a slight tilt. I believe this is
due to the mounting of the yoke to the tower.
We may try to change it.

Comments:
- 45: PROPS, Site , Sat 27-Jun-1998 12:01:52 CDT, Prop direction differences
There is a difference in the ASTER prop directions.
When looking at data over a long time period with 1 hour
averaging, the 2m and 6.5m are about 2 degrees off compared
to the 1m. While the 4.5m and 9m are about a degree off.
The boom alignment was checked on the 1m and 2m. There was
no changed when the vanes were re-aligned. The error may be
due to the direction angle measurements. When shooting the
angles, the 1m and 2m where shot without moving the tripod.
The same conditions were used on the 4.5m and the 6.5m.
We will try shooting the angles again in the next few days
to see if this answers the question.
- 44: LOG, Site , Sat 27-Jun-1998 09:50:55 CDT, NCAR/OKMN comparisons
We are now ingesting OKMN data and I note the following comparisons:
Temperature:
1.5m and 9m temperatures agree within better than 0.1 C at night,
but NCAR temperatures are 0.1-0.2 C cooler during the day. The
difference is smaller at 9m than at 1.5m, consistent with a
wind-speed-dependent radiation error in the OKMN shield.
As a consequence, T(9m) - T(1.5m) is greater (more positive) for NCAR
than for OKMN, by 0.05-0.1 degC during the day and 0 to 0.05 degC at
night.
Winds:
NCAR winds speeds are 10-20 cm/s higher than OKMN at both 2m and 9m.
A 48-hour average, June 26 (1030 CDT) -28 (1030 CDT), gives
NCAR OKMN NCAR-OKMN
9m 7.080 7.014 0.066 m/s
2m 5.468 5.440 0.028 m/s
9m-2m 1.612 1.574 0.038 m/s
Pressure:
There is a 1-2 mb difference between NCAR and OKMN which suggests
a temperature contamination of one of the barometers.
The error decreases as shadows from the prop and sonic towers pass
across the NCAR barometer enclosure, indicating a temperature error
in the NCAR barometer.
Rsw.in:
NCAR > OKMN during day by 10-20 W/m^2
OKMN = 0.985*NCAR + 2.3 W/m^2
Hysteresis in the xy plot suggests a leveling difference.
NCAR ~ -3 W/m^2 at night; OKMN = 0
Rsw.out:
NCAR < OKMN during day by 10-20 W/m^2
OKMN = 1.1*NCAR + 1.0 W/m^2
This difference may be affected by the albedo. It appears that the
surface under the OKMN pyg is "brighter" than that under the NCAR.
NCAR ~ -1 W/m^2 at night; OKMN = 0
Rlw.in:
OKMN = 0.973*NCAR + 10.4 W/m^2
But the xy plot is noticeably non-linear, again with hysteresis
suggesting a leveling difference.
Rlw.out: No OKMN data; Tcase.out and Tdome.out missing
Rnet:
NCAR > OKMN during day by up to 25-30 W/m^2
NCAR < OKMN at night by about 10-15 W/m^2
Rnet.OKMN = 0.944*Rnet.NCAR + 8.74 W/m^2
Rnet.OKMN is REBS SN# Q96101 from NCOM
Sonic:
u.NCAR = 0.97*u.OKMN + 0.015 m/s
v.NCAR = 0.93*v.OKMN + 0.72 m/s
u'u'.NCAR = 0.91*u'u'.OKMN + 0.017 (m/s)^2
v'v'.NCAR = 0.93*v'v'.OKMN + 0.010 (m/s)^2
w'w'.NCAR = 1.10*w'w'.OKMN + 0.002 (m/s)^2
u'w'.NCAR = 1.38*u'w'.OKMN - 0.007 (m/s)^2
v'w'.NCAR = 0.64*v'w'.OKMN - 0.034 (m/s)^2
u*.NCAR = 1.14*u*.OKMN + 0.022 m/s
tc'tc'.NCAR = 0.99*tc'tc'.OKMN - 0.002 (degC)^2
w'tc'.NCAR = 1.13*w'tc'.OKMN - 0.003 (degC)^2
June 29
Found that the ATIs were tilted by about a degree in one direction
and the Campbells about a half degree in the other. This appears to
explain about 2/3 of the differences in u* and w'tc'. See logbook
entry #50. Note that tc'tc' is in good agreement, suggesting
neglible (or canceling) errors due to covariance calculations or
differences in high-frequency sampling.

- 39: HYGRO, Site , Thu 25-Jun-1998 14:46:41 CDT, 1.5m TRH back up
The 1.5m TRH is back on the tower. I hope I have
found the problem. Using the scope I was able to trace
down an intermittent contact between the transmit pin, #21,
on the 68HC11 chip and the socket. I pulled the chip out
and played around with the socket contact. It appears the
chip seats too deep in the socket. Pads were added to the bottom
of the chip. In addition, I did not seat the chip completely
down. If the sensor is alive after 48 hours then I believe the
source of the problem has been found.
- 38: HYGRO, Site , Thu 25-Jun-1998 11:28:27 CDT, 1.5m TRH stopping
The 1.5m TRH is still stopping after 24 to 48 hour
operation. The problem appears to be a open contact in
the transmit line. After failing in the field the sensor
is brought back into the trailer and tested. after about 1/2
to 1 hour the sensor fails. In the failed mode, I have tried to
remove the electronics. Moving the board out about 1" gets the
sensor running again. It does not go thru a reset. It just starts
sending data out again. This is why I believe it is an open
circuit somewhere. We may need to reseat the processor and
rom chips. I will wait until we get the chip pullers.
I have tried soldering points on the board where the transmit
signal would flow. This has not solved the problem. The interface
connector block between the sensor board and the serial cable has been
replaced.

9m hygrothermometer, which is on a longer boom, also pointing
to the SW.

- 26: BASE, Site , Mon 22-Jun-1998 17:00:40 CDT, NETWORK NUMBERS
Here are some issues with respect to the network link. The
link was setup using the AnyTwist box (refer to drawing on
bulletin board.
(1) The Transceiver has 4 lights to look at. On top of the
unit are 3 lights: green (our network), amber (transceiver link),
and green (power). There are symbols above the lights which give
you a clue as to what they represent. The network and transceiver lights
should be blinking. The power light should be on. There is a 4th light in the
back of the unit which is amber and represents the antenna connection.
(2) If the network link goes down you should check these lights.
If our network light is out then it is our problem. If any of the other lights
go bad then call Harolda at 325-1555 and provide her with any information; ie,
light status, etc. She will pass on the informaion to the necessary people
to get things going again.
(3) IP addresses:

- 18: HYGRO, Site , Sun 21-Jun-1998 10:31:22 CDT, Replaced hygrothermometer filters
At about 10:15 CDT, I replaced goretex filters on the hygrothermometers
The 0.5m, 1.5m, 4.5m hygrothermometers have the filter holders with
4 large slots. The 6.5m and 9m hygrothermometers have the filter holders
with 8 smaller slots.
- 17: HYGRO, Site , Sun 21-Jun-1998 09:18:28 CDT, June 19: moved TRH intercomparison
On June 19, around 1300 CDT, we transferred the hygrothermometer
intercomparison from the radiation sawhorse to a horizontal tower
section supported by two ladders. This is located about 15m north
of the hygrothermometer tower, oriented E/W. The hygrothermometers
are at a height of 1.5m, pointing to the south.
With the radiation shield intakes pointing upwind (south) rather than
downwind (north), the differences between the temperatures have been
reduced from a range of about 0.2 C to a range of about 0.1 C.

At 17:15 CDT, removed the gortex shields from the hygrothermometer
50Ys to determine the effect on the temperature intercomparison.
Also noted that the 50Ys had the following PRTs
0.5m slow
1.5m fast
4.5m fast
6.5m slow
9m slow
where "slow" is the original Vaisala PRT and "fast" is a faster
response PRT used to replace the Vaisala PRT on several 50Y sensors
prior to Flatland96.
9:12 CDT, June 21
Comparing last night's data to the previous night indicates no
significant effect of running without the filters
- 14: SOIL_SENSORS, Site , Sat 20-Jun-1998 15:13:26 CDT, Buried soil sensors
Buried three sets of soil sensors 1-2m north of NW leg of radiation stand.
They are arranged roughly east (site 1) to west (site 3).
Placed heat flux plates at a depth of 2 inches (5 cm).
Placed CS615 soil moisture probes at a depth of 1.5 inches
(placed top of front plate of insertion tool at level of surface);
I intended to place the CS615s at a depth of 1 inch, but this would
put the electronics too close to the surface to cover with sod.
I inserted the soil temperature probes at an upward angle
from a depth of 2 inches.
Inserting the soil temperature probes from below has the advantage of
burying the cable; the disadvantage is that I am unsure of
the exact location, relative to the surface, of the tip of the probe.

Proceedures To Get More Air Time For Cellular Phone
1.) when placing a call, the operator will atuomatically
inform you as to how much time is left.
*note* long distance calls eat time much faster than
local calls
2.) when getting short on air time, call Tom Davies in
UCAR finance, and ask for more. (303) 497-8872.
He will contact the appropriate people at Norman Cellular,
and pay for more time.
3.) If you cannot contact Tom Davies, drive to Norman Cellular,
corner of 24th and Main St. LaDeana Roberts is the
person familiar with our account. Simply pay for a new
phone card and put the bill on your travel voucher.
- 8: FAST_T, Site , Thu 18-Jun-1998 17:36:12 CDT, Fast T calibration
Steve ran a calibration on the fast T at 4.5m, cycling between "ambient"
and "cal" ("ambient" + 5 degrees). Switching was done at approximate
10 sec intervals from 22:32:20 - 22:33:50 GMT.
- 7: HYGRO, Site , Thu 18-Jun-1998 13:05:22 CDT, Hygrothermometer intercomparison
Set up 5 hygrothermometers this morning at same level on radiation sawhorse;
at a height of about 2m; intakes pointing north.
Sawhorse is oriented roughly E/W and is located near base of hygrothermometer
tower.
- 6: FAST_T, Site none, Thu 11-Jun-1998 12:29:10 CDT, How to examine cals
Steve S. asked me to review how the fast T calibration data are processed
in S. Here is an example:
dpar(lenmin=3)
dpar.now()
dpar(hour=15,min=20)
iod <- prep("volts.102.ragwort")
x <- read(iod)
close(iod)
fun.fastT.cal(as.vector(x),navg=10)
The "as.vector" is needed since fun.fastT.cal isn't expecting an ATS object.
The sequence of dpar calls is my way of being lazy and avoiding entering
today's date (when the data were taken).
Note that fun.fastT.cal is expecting a VOLTAGE change of about 0.5 V.
It doesn't work if the calibrated "t.4.5m" signal is used.
- 5: ADAMS, Site , Mon 08-Jun-1998 10:25:12 EDT, Bad Datel
Datel S/N 440690 seems to be marginal, and causes backplane
problems.
When ragwort (S/N 9006) is the Matrix CPU, it does not receive A/D
data (I assume it is not receiving interrupts from the Datel). The
bootup goes well, no errors are seen. The green LED is pulsing at a 1
second interval (the A/D interrupt period) which I don't think is
normal.
A week ago ragwort was reporting "HSTSTA ACK failed" messages on boot
indicating it couldn't talk to the Datel at all (though I'm not sure
that it was with #440690). At that time I blamed ragwort. It would
also intermittently have problems talking to the ironics, reporting
"serialSock: read 1024 bytes, result -1: S_errno_ECONNRESET", which
causes the whole data acquisition process on the Matrix to crash.
When cosmos (Matrix S/N 940211101) is swapped in (configured as
ragwort), it seems to work with Datel 440690 (the A/D data comes
through), but gets an ECONNRESET error talking to the Ironics.
When the 440690 is replaced with Datel 320689 all is OK, with either
Matrix card, so that is why I'm blaming the Datel, and I'm hoping
that both of these problems (no A/D data and ECONNRESET with the
Ironics) can be traced to the Datel. It's either that or El Nino.
Further tests: Tried Datel 440690 with marigold. It came up ok and
actually worked for a few minutes, then died. It then reported
HSTSTA ACK errors on bootup.
Currently we're running 440690 in cosmos, with only channel 107
and no serial channels active. So far so good. It could act
as a spare datel if used with cosmos in this way.
- 4: SONICS, Site , Mon 08-Jun-1998 09:50:36 EDT, Sonic testing
ATI sonic, S/N 980504, as ragwort channel 201 has showed a few spikes
(1 or 2 per hour) on V during testing in the staging area. Other
components were clean.
Serial #980505 as ragwort 200 showed no spikes.
They were configured with a 5ms sampling interval, 10
samples/average, giving 20hz output, 9600 baud, with 2 levels and
nsamples also output.
The sonics were next to each other, extended from a benchtop, with
the V arm of #980505 (which didn't spike) about 3 inches from a
wall.
Binary mode:
In an effort to lower the serial overhead I tried to configure the
sonics in binary mode. It mostly worked. U,V,W,Tc looked OK, but
the levels (which were one byte each) were always 0. There did not
seem to be a way to get nsamples output in binary mode.
- 3: LOGISTICS, Site , Sun 07-Jun-1998 22:34:48 GMT, staffing
Here is an update on my proposed staffing schedule for OASIS. Let me
know if this is acceptable and then we can finalize housing reservations
at the Mariott Residence Inn in Norman.
Tom
Assumptions:
Steve S and Kurt leave Boulder on June 15; meet trailer in
Norman ~mid-day June 16; Tom flies to Norman morning of June 17.
Official operations begin on Saturday, June 27
6 weeks of operations end on Friday, August 7
4 days to tear down and pack, August 8-11
This should accomodate 3 x 3-week shifts with overlap:
Kurt: June 15 until whenever set up and initial debugging completed;
Return around August 7 for teardown
Steve S: June 15 - July 5
Kathy July 3 - July 23
John : July 21 - Aug 11
Tom: June 17 - July 7
Steve O: July 5 - July 25
Tony: July 23 - Aug 11
The last shift has a small uncertainty associated with the start date
of operations and could be a few days longer or shorter. If this is
more than a day or two, we will adjust everyone's schedule.
