- Sat Feb 05 22:07:52 1994 KRYPTON :Krypton A/D channel seems okay spo
Krypton A/D channel seems okay
I just used the Datel dial-a-volt to pump a few voltages
directly into the A/D channel at the 18-pin connector at
the ADAM front panel. I read the voltages out using "prep"
with a prep.config which specified a normal linear gain.
in: out:
0.000V 0.002V
1.000V 0.998V
-1.000V -0.994V
This is close to consistent with a bias of 3 mv, and a gain
low by 0.5%.
I don't think this is bad enough to have caused the high humidities
we are seeing. Note that the Krypton is reading about 0.168V - this
seems quite low.

Krypton tests:
I have tried several things today:
- Powered up Krypton serial #1133 in trailer - get NO voltage on the
output. (I checked and do get +12VDC inside the electronics box.)
I don't see a "glow" in either lamp.
Thus, I think #1133 is dead.
- Reseated all connectors (even on the tower) on #1101. No change.
- Swapped in electronics box for #1133 with #1101. No large change
(hard to tell exactly since I was trying to read the DVM on the
ground from 10m up).
- Didn't see a "glow" in either tube of #1101.
Thus, I think #1101 has a weak source tube.
We should send #1133 back to Campbell to have them get it running again,
and then swap back with #1101.

UW sonic ID's wrong
I've just realized that the ID's for the UW sonics are wrong.
(This is partly my fault, since I told Kurt I "didn't know" which
electronics box went with which array, but one box should have
gone with one array.) The triangular array is always UW1, (since
it was built first) and the cal_files, uw.sonic.1 and uw.sonic.2
assume this. I've just reprogrammed the HC11 IDs to reflect the
correct setup, and will check that the labeling of the boxes is
correct.
I'll now recompute the zero calibrations of a few days ago, since
the pathlength used in the speed-of-sound zero calibration was
wrong. I'll also make sure prep.config is pointing to the
correct files.
Sometime, we should check the FOOTPRINT logbook to make sure that
this switch wasn't in effect then (causing wrong angles to be
used by the calibration routines).

presumably is above freezing. I didn't notice snow on the psp.in.)

Misc problems:
. There is a minor leak around the top of the "boot" on the chem trailer
side.
. While attempting to shovel snow off the roof (near the boot), I found out
that the roof has a thin coating, which I scraped off of a few rivet heads
on the chem trailer near the door. I attempted to patch them with RTV,
but it didn't stick too well given that it was snowing at the time and
cold.
. Also, the chem trailer air conditioner has been making weird sounds -
like a bearing is bad in the fan. The fan appears to stop and then
there are strange smells while on "heat". Thus, we've been leaving
it off altogether. The data trailer unit appears to heat both adequately.

This was done about 1204 (local) so I was climbing during the IOP.
This done to test whether sonic temperature spikes are real. Most are!
We have not calibrated this, though I did put the switch through its various
settings 0-oper-cal-oper..., with 2 sec per setting just after replacing
the fast T. This should have been about 1704.

noon status
Weather: Started out as mostly clear, but now overcast. Light East winds, so
no downwash. Still crusty snow on the ground.
Plant: Ran yesterday from 1130-1615 (local). 1200-1500 was on low load (4 MW)
and 1500-1615 was at "baseline" load (62 MW).
We thought we saw downwash with high temperature bursts, but most of
these probably were the air from the heat exchanger. NOx concentrations
were all low; however, the LIDAR claimed to see downwash. Lloyd will
have fun sorting all this out.
Today, we were to have run from 1100-1500, but the CT's fuel injecters
are clogged. We are now waiting for them to be cleaned, which should
take an hour or so. If they start up, it will be a "plume rise" ops,
which shouldn't need much from ASTER.

There wasn't time to do a good cal when we installed t.4m.cav1, but
I did go through a quick cal cycle without having the chamber installed.
The data are noisy, but I've just played around in S, and Gordon and
I agree that the jump corresponded to about 4.4 C. Thus, the
gain should be 0.00173 for the period between installation at
on jday 45 and the adjustment at about 1348 on jday 46. I'll
update the cal_files after processing the jday 46 calibration.

incorrect MSWindows config.
Data has not been checked by a meteorologist.

I could connect to that modem from ASTER, but was not

- Fri Feb 18 16:00:20 1994 SONIC :uw boom angles spo
uw boom angles
The uw calibration routines use a coordinate system which has zero azimuth
as the angle between the two path "A" transducers. Gordon (Wed.) and
I (Thur.) have reshot these sonics, aligning the faces of the "yellow"
and "blue" transducers vertically. These angles are:
uw.4m.far: 120deg 21'40"
uw.10m.up: 154deg 37'20"
I've just entered these into sonic.config.S.
We should remember to shoot path A in the future. (Gordon thinks we
should align the sonics with the boom. In fact, either would work
now that we "know" the difference between these angles.)

- Fri Feb 18 21:00:47 1994 SONIC :Tower vibration spo
Tower vibration
I've noticed that the sonics "yaw" in high winds. This probably is due
to having the psycs on the same tower, increasing the wind loading.
We should look at v-component spectra to look for this. An easy way to
check for periods when this happens is to look at the variance of
alev and blev - I think blev especially - on the ATI's.
Also note that the level signals on atik.10m.cav1 are not on scale. They
indicate that the tower is not level, although we adjusted it with the
theodolite. I don't think the tower has shifted, since I recall that these
signals have always been off since we got the tower up.

- Tue Mar 01 19:03:47 1994 FASTT :PROCEDURE for FAST T cals: srs
PROCEDURE for FAST T cals:
These are notes on fast T cal procedures.
Tower work:
tools: 2 DVOMs
1 small screwdriver
1 thermocouple cover with meter unit
1 new fast T probe if needed
1 long cable to interface to splitter
1 splitter box for getting fast T signal
The splitter box allows you to monitor the signal from the
fast T while the signal is still going to the ADAM. The 9
pin cable going to the fast T along with the long meter
cable attach to the splitter. The other end of the splitter
goes to the breakout box (attached to the channel for the
fast T).
Attach the other end of the meter cable to one of the
DVOMs. Set it to dc volts. If the fast T probe is broken
the meter will read greater than 5 volts.
Attach the other meter to the thermocouple unit. Set the
meter to dc 300 mvolts. Also set the thermocouple unit
to degrees C. It will read temperature in degrees C
( 12.3 mvolts = 12.3 C).
You want to place these meters such that you can read
both of them at the same time when adjusting the bridge.
Replace the fast T probe if required and place the
thermocouple unit over the probe. Allow the temperature
to stabilize.
Adjustment procedure:
While monitoring both meters adjust the offset pot so
that the absolute value of the fast T agrees with the
thermocouple (remember the output for the fast T should
be multiplied by 10). The toggle switch should be in the
operate position. Now move the toggle to "cal". There
should be a gain of 5 degrees in the fast T output.
If not, adjust the gain pot. This may take a few
iterations of switching the toggle back and forth.
Once this is done you should check the absolute value
again.
Collection of data set:
In order to determine the true gain you need a data set
to look at. Set the toggle switch to zero and leave for
seconds. Now switch the toggle to operate for 5 seconds
then to cal for 5 seconds. Repeat this step for at least
times. Set the switch to zzero one more time,
seconds, then back to operate. Remove the thermocouple
unit.

PROCEDURE for FAST T cals:
Notes on fast T cal procedures.
Tower work:
tools: 2 DVOMs
1 small screwdriver
1 thermocouple cover with meter convertor unit
1 splitter box for getting fast T signal
1 long cable to connect one DVOM to splitter box
1 new fast T probe if needed
The splitter box enables the person on the tower adjusting the fast T sensor
to monitor the signal without interupting the data flow to ASTER.
The box interposes in the data cable run, at the break-out-box. The long cable
is attached to the first DVOM carried up the tower.
This first DVOM is set on the dcvolt scale.
The output shown should read of the order ?.?? dcvolt.
degree C corresponds to ?.? dc volts
If the voltage shown is > 5 volts dc then the probe is broken.
The splitter box allows you to monitor the signal from the
fast T while on the tower. The signal still goes to the ADAM. The 9
pin cable going to the fast T along with the long meter
cable attach to the splitter. The other end of the splitter
goes to the breakout box (attached to the channel for the
fast T).
Attach the other end of the meter cable to one of the
DVOMs. Set it to dc volts. If the fast T probe is broken
the meter will read greater than 5 volts.
Attach the other meter to the thermocouple unit. Set the
meter to dc 300 mvolts. Also set the thermocouple unit
to degrees C. It will read temperature in degrees C
( 12.3 mvolts = 12.3 C).
You want to place these meters such that you can read

getting into Splus open a display window, X11().
Use the following command:
fun.plot.prep("didname",year,hour,"archivefilename")
This will create an plot of the data. Use this
plot along with the functions of fun.plot.prep
to determine the time window.
Now use the function fun.fastT.cal.get to determine
the gain.
fun.fastT.cal.get("didname","adam",channel#,
day,hour,min,"filename",nummin)
This function will provide a graphic display of
the data along with a vector of gain values based
on each transistion from operate mode to cal mode.
NOTE: the vector may have other values based on the
value you used for parameter nummin.
To calculate the proper gain value to be put into
cal_files, save this vector. Apply the vector to
the equation below.
gain <- (50/32768)*(5/mean(abs(dT[i:j])))
This gain value will get loaded into the proper
cal file. Look into the directory /home/aster/cal_files

PROCEDURE for FAST T cals:
Notes on fast T cal procedures.
TOWER WORK:
tools: 2 DVOMs
1 small screwdriver
1 thermocouple cover with meter convertor unit
1 splitter box for getting fast T signal
1 long cable to connect one DVOM to splitter box
1 new fast T probe if needed
The splitter box enables the person on the tower adjusting the fast T sensor
to monitor the signal without interupting the data flow to ASTER.
The box is interposed in the data cable run at the break-out-box.
The long cable is attached to the first DVOM carried up the tower.
This first DVOM is set on the dcvolt scale.
The output shown should read of the order ?.?? dcvolt.
degree C corresponds to ?.? dc volts
If the voltage shown is > 5 volts dc then the probe is broken.
The thermocouple unit is attached to the second DVOM which is set on the
mvdc scale. The thermocouple unit is set to Degrees C.
The output will read in degrees C. 12.3 mv = 12.3 degrees C.
When the fast T system is being adjusted both meters should be hung
such that they can be viewed at the same time.
The fast T probe is replaced if required and the thermocouple unit
is place to enclose the probe. The temperature is allowed to stabilized.
ADJUSTMENT PROCEDURE:
With the toggle switch in the OPERATE position adjust the ZERO or OFFSET
pot so that the absolute value of fast T (the first DVOM value X 101).
agrees with the value given by the thermocouple (the second DVOM value).
Move the toggle switch to the CAL position.
The reading for the fast T should be 5 degrees C higher than the TC temp.
If not adjust the GAIN pot.
Iterate if necessary until the temperatures agree to within a few tenths
and the JUMP is 5 degrees C +_ 0.2 degrees C
COLLECTION OF DATA SET:
In order to determine the true gain a data set is needed.
To collect such a data set:
set the toggle switch to ZERO and leave for 10 seconds,
set the toggle switch to OPERATE and leave for 5 seconds,
set the toggle switch to CAL and leave for 5 seconds,
repeat these OPERATE and CAL sequences at least five times, then
set the toggle switch to ZERO and leave for 10 seconds.
Remove the thermocouple unit, chech that the fast T system is still
functioning, collect the rest of the equipment, and climb down the tower.
DATA PROCESSING:
To compute the gain factor use Splus functions, first to recognize
the time period when the calibration occured, then to define the
actual gain factor.
Move to the appropriate directory, viz: /data/DOWNWASH94/raw_data/upwind
Evoke Splus and open a graphics window with X11().
Run the Splus function:
fun.plot.prep("didname",year,day,"archivefilename")
fun.plot.prep("t.10m.up",1994,60,"upwind/fast060160000")
The program asks for start and stop times. On the first iteration bracket
the calibration period and then accurately determine the time window.
Now determine the gain with the Splus function"
fun.fastT.cal.get("didname","adam",channel#,day,hour,min,"filename",nummin)
fun.fastT.cal.get("t.10m.up","cosmos",100,60,20,15,"upwind/fast060160000",2)
This function will provide a graphic display of
the data along with a vector of gain values based
on each transistion from operate mode to cal mode.
NOTE: the vector may have other values based on the
value you used for parameter nummin.
To calculate the proper gain value to be put into
cal_files, save this vector. Apply the vector to
the equation below.
gain <- (50/32768)*(5/mean(abs(dT[i:j])))
This gain value will get loaded into the proper

I don't trust the value for A since there were large fluctuations indicating
wind leakage. Also, the value for S might have been off if the zero chamber
wasn't kept at air temperature (though Gordon (one of the people doing the
cal) should have known this).
The values for B and C are quite close to the values determined for day 035,
of -2 and -67, respectively.
Unless the wind speed comparisons indicate that we should do something
different, I think we should not change the zeros from the day 035 values.

uw.10m.up day 065 zero processed
Searching the data, guided by comment 132, the following are the times
for the zero chamber:
A: 14:00:48.090-14:01:27.480
B: 14:01:34.530-14:02:14.870
C: 14:02:19.170-14:02:54.160
Around these times, T=1.8C, rh=52%, p=1026mb from upwind sensors
Thus speed-of-sound was:
vpres <- 0.52*fun.satvp(1.8)
mixr <- (0.622*vpres)/(1026-vpres)
spec.hum <- mixr/(1+mixr)
Tv <- (1.8+273.15)*(1+0.61*spec.hum)
cc <- 20.067*sqrt(Tv)
results in c = 332.97 m/s
Pathlength for path A is 0.1999m, therefore counts should be
.1999/332.97 * 4 MHz * 16 up-and-down firings/sample = 38423 counts

P.S. I've just plotted wind speeds from uw.10m.upwind vs. prop.6m.upwind
for the entire DOWNWASH project, and see the expected behavior that the
prop is about 10% lower than the sonic (except for obvious glitches).
Thus, there is no evidence that the A channel really had a bias of -600
counts, which would be about 10 m/s.
