4m ATI SONIC
Steve put the new ATI sonics up yesterday at 4m and 10m on the
flux tower. The output signals from both were poor, so today
we looked at the received pulses with the 'scope and found
that they were quite noisy. We brought the 4m sonic into the
trailers and it performed good both within the trailer and
outside on the tongue. When we remounted it on the flux tower,
after recalibrating it on the trailer tongue,
we found that the noise was apparently being generated by the
fast T. Steve tried various substitutions for cables and also
the bridge itself with no improvement. At that point we simply
disconnected the 4m fast T in order to get good signals from
the sonic. I think that this also improved the 10m ATI signals,
but they are nevertheless still poor, and disconnecting the 10m
fast T only made its signals worse! We have now turned off the
10m ATI since its output was obviously still bad. Tomorrow,
weather permitting, we will see if grounding the sonic booms
reduces the noise on the received pulses.

external ground only between the electronics case and earth

We hooked up the 4m sonic cable to the 10m sonic
electronics and got good data from the 10m sonic,
indicating that the problem with the 10m sonic is
with the cable or with the array.
Looking at the 10m ATI sonic received pulses with the
'scope, the v axis has no received pulse. Allen
tightened the crystals on the v axis and this brought
the signal back. He also found most other crystals
loose and tightened them as well. We then redid the
calibration procedure on the tower with the exception
of the vertical axis. However, the 10m sonic is now again
spiking simultaneously on all channels.

TESTING FOR SONIC NOISE SOURCE
Have spent the afternoon searching for the source
of the noise on the 10m ATI sonic. With only the
10m ATI sonic running on marigold, there were
still synchronous spikes on the 10m ATI.
Then turned the other sonics, fast T's and hygrometers
back on. The Gill output is now very noisy and
there is no output from the 4m ATI v component
(just 9999).
In order to get the 4m ATI running we needed to
'goose' it with a while logged
in through rserial. In addition, when it came
back on the first time there was no data from the
level sensors. We tried communicating with rserial
to turn the ATI A/D channels back on (the level
sensor channels), but only managed to put the ATI
in verbose mode. We suspect some communications
protocol mismatch. We hooked the Toshiba directly
to the ATI and easily got it back into terse mode
with the A/D channels turned on.

because it corresponded with pluggin the

also hopefully the reason for the noisy data

PROGRAM USE TO CALCULATE SURFACE HEAT FLUX TO BE USED FOR STORMFEST
THIS PROGRAM IS TO CALCULATE THE SURFACE HEAT FLUX, G, FROM THE
8cm HEAT FLUX, G8, AND THE SOIL TEMPERATURES AT 1cm, 3cm, 5cm, AND 7cm
The relationship used to relate the measured soil heat flux determined at 8cm
to the heat flux at the very surface is:
Gi = G8i +(Csoil * 0.08 * (Tsoil(i+1) - (Tsoil(i-1)) / (t(i+1) - t(i-1))
where: Gi is the surface heat flux at time i
G8i is the 8cm heat flux at time i
Csoil is the heat capacity of the soil
Tsoil(i-1) is the weighted mean temperature of the top 8 cm
of soil at time i-1
Tsoil(i+1) is the weighted mean temperature of the top 8 cm
of soil at time i+1
Tsoil(i+1) = (T1cm(i+1) + 3*T3cm(i+1) + 3*T5cm(i+1) + T7cm(i+1))/8
Tsoil(i-1) = (T1cm(i-1) + 3*T3cm(i-1) + 3*T5cm(i-1) + T7cm(i-1))/8
i+1 refers to the data recorded at t(i+1) seconds
i-1 refers to the data recorded at t(i-1) seconds
(t(i+1) - t(i-1)) is twice the time interval = 2 * 5min = 600s
Csoil = (1.05 + (6.09 * gravmoist)) * 10**6
# The values for the coefficients were derived from estimates of the soil propertites
# at the Sebetha site. They were provided by Jay Ham, KSU.
# Bulk density = 1.45 g cm-3
# Mineral particle density = 2.65 g cm-3
# Organic material density = 1.00 g cm-3
# Water density = 1.00 g cm-3
# Volumetric mineral fraction = 0.55
# Volumetric organic fraction = 0.01
# Volumetric water fraction = 1.45/1.00 * gravmoist
# Csoil = (1.9*volumetricminfract + 2.5*volumetricorgfract + 4.2*volumetricwaterfract)
# = (1.9*0.55 + 2.5*0.01 + 4.2*1.45*gravmoist)
# = (1.05 + 0.025 ) + 6.09 * gravmoist
# = ( 1.08 + 6.09 * gravmoist)
G should be calculated for each of the three locations, furrow, intermediate,
and ridge.
Furrow: Gfur corresponds to G1.8cm, T1.soil, and T1.index
Intermediate: Gint corresponds to G2.8cm, T2.soil, and T2.index
Ridge: Grid corresponds to G3.8cm, T3.soil, and T3.index
Finally a mean G should be calculated for the surface>
G = (Grid + Gint + Gfur)
NOTE ADDED 21 APRIL 1992
In the field five dirt clod were collected trimmed to a regular
shape and dried in the oven to constant weight. They were then wax impregnated
using parawax and a heat gun. They were returned to the lab and on 20 April
their bulk densities determined using the recorded mass and the volume
determined by immersion in water contained in a graduated beaker.
The accuracy of the volume determination was only +/- 5 cm3.

stored in plastic containers in the lab. In order to determine
mineral particle density a portion of the soil was oven dried at 110 C
and then three aliquots of ~20.0 cm3 were first weighed dry and then
saturated with water.
Sample C' was done 29 Jan, the others on 5 Feb
Sample C' Sample A Sample B Sample C
________________________________________________________________________________
Volume cm3 18.1 20.26 19.76 18.40
Dry mass g 19.18 20.56 19.26 19.08
Sat mass g 28.54 34.74 29.46 29.05
Pore water g 9.36 14.18 10.20 9.97
The following relationships were applied:
bulkdensity* = dry.mass/volume
watervolfrac* = (pore.water/volume) * waterdensity
= ((sat.mass - drymass)/volume) * 1.0
minvolfrac = 1 - watervolfrac*
= 1 - ((sat.mass - drymass)/volume) * 1.0
mindens = (dry.mass/volume)/minvolfrac
= bulkdensity*/minvolfrac
Sample C' Sample A Sample B Sample C
________________________________________________________________________________
bulk density* g cm-3 1.06 1.02 0.98 1.04
watervolfrac 0.52 0.70 0.52 0.54
minvolfrac 0.48 0.30 0.48 0.46
mindens g cm-3 2.21 3.40 2.04 2.26
NB bulkdensity* is not the true bulkdensity = blkdens obtained
from the measurement of soil clods. bulkdensity* is the effective
density of the dried sieved soil which is processed to determine the
mineral grain density.
Likewise watervolfrac* is also a parameter used solely for this purpose.
A value of mindens and of minvolfrac were calculated from the mean of the
above, ignoring Sample A
Mindens = 2.17 +_ 0.09 g cm-3
Minvolfrac = 0.47 +_ 0.01
Bulk density = 1.38 +_ 0.16 g cm-3
An upgrade can be made to the previous estimate of Csoil
# The values for the coefficients were derived from the soil properties
# of samples taken at the Sebetha site and analysed in the lab.
# Bulk density = 1.38 g cm-3
# Mineral particle density = 2.17 g cm-3
# Organic material density = 1.00 g cm-3
# Water density = 1.00 g cm-3
# Volumetric mineral fraction = 0.47
# Volumetric organic fraction = 0.01
# Volumetric water fraction = 1.38/1.00 * gravmoist
# Csoil = (1.9*volumetricminfract + 2.5*volumetricorgfract + 4.2*volumetricwaterfract)
# = (1.9*0.47 + 2.5*0.01 + 4.2*1.38*gravmoist)
# = (0.89 + 0.025 ) + 5.80 * gravmoist
# = ( 0.92 + 5.80 * gravmoist)
Csoil = (0.89 + (5.80 * gravmoist)) * 10**6

covar_ragwort was restarted at 1600Z with these temperatures
added in the covariance groups.
After viewing plots of the diurnal cycle, we decided that
the indices for 1cm.Tsoil.fur and 3cm.Tsoil.fur were switched.
The calibration parameters then were updated from those used
for SJAVQS91, to those determined in the calibration lab
on Jan 13, 1992.
covar_ragwort was then restarted at 21:10Z with the new
calibration parameters and the 1cm and 3cm furrow channel
switched.
- 152: ADAMS , Site none, Sun 01-Mar-1992 23:56:02 GMT, Marigold went down & missing file probl
Marigold went down at 21:36Z, jd=61 for unknown reasons.
Then, however we were not able to bring it back up, and the
other adams also would not come up successfully. Finally traced
the problem - ingest was not able to run on ASTER because
/home/aster/config/channel_config was missing.
It had been a link to $ASTER/projects/$PROJECT/ops2/channel_config
but I (gdm) had recently moved the files on ops2 to ops1, since
(I thought) ops2 was not really necessary.
Once we re-linked /home/aster/config/channel_config to the file
on ops1, ingest would run OK.
The ingest error message was misleading, it was reporting an error
in opening sio_converters, when actually the fopen() was failing
on channel_config.
Adams were brought up at 23:35Z, but then marigold died again
at 23:53.

old transceiver had its 'SQE' active. We will
disable it and try the transceiver tomorrow if
marigold stays up through the night. The only

and calibrate with the chamber covering the sensor.
I edited the data file, removing a few points at the
transition, and then used the S function fun.fastT.cal
to average 10 points on either side of each transition.
For 4 m the results are:
> fun.fastT.cal(fastT.4m[,1],10)

- 227: RAD , Site none, Mon 17-Aug-1992 15:55:06 GMT, Post calibration of Tsoil probes:
Post calibration of Tsoil probes:
I had Allen do a calibration run on the Tsoil units
after he repaired the boards. Results of the tests can
be gotten from Steve Semmer.
The test consisted of placing the probes in an
aluminum block with the temperature reference device.
The electronics were also in the chamber at the time of the test.
A soak time of 1 hour was used at each temperature.
The first sensor looked pretty good.
There was a definite change in slope with respect to the temperature.
This may have been due to the electronics response to temperature
changes. Calibrations before StormFest and FootPrint did not allow
for the electronics to be subjected to changes.
All four probes followed each other.
The other two sensors did not fair as well.
There was a slope change; however, the tracking between sensors
was not that good. I will have Allen do another 3 point check
on this units.
The table below specs the worst error of each probe in the
range of -10C to 20C (STORMFEST). The table also has the error
band if a simple linear fit were applied over the specified
temperature range. The error information is computed using the
pre-calibration coefficients with the post-calibration voltage
outputs.
The question to answer is do we want to apply a correction to
the STORMFEST data. The components changed on the circuit
boards should not have had a major impact on the sensor output
since the impedence of the mux swithes are low compared to
the thermistor values.

Don't trust some temperature/humidity profiles.
After trying to get the Bowen ratio and flux-profile relations to
compare reasonably with eddy-correlation flux estimates, I have
found that several of the T/RH profile levels are suspect.
fun.Tddiff.plot(50) shows a case when the 10m temperature is bad and
fun.RHdiff.plot(50,7) shows that the 2m RH is bad during this period, thus
fun.qdiff.plot(50,.5) shows bad q's from 2m and 10m.
Also, it is not too obvious, but fun.RHdiff.plot(60) shows the 4m RH is
slightly off, and thus crosses zero early at 15Z. The Bowen ratio calculated
from (T7-T1)/(q7-q1) agreed much better than (T7-T4)/(q7-q4) with the
eddy-correlation ratio w'T'/w'q' for this period. (Of course, "T" here is
potential temperature.) Thus, I ended up using 1,4,7 for flux-profile
relations and just 1,7 for Bowen ratios...Steve

- 235: FASTT , Site , Fri 14-Feb-1997 22:08:40 GMT, Cal factors for fast T probes
The calibration factors for the fast T probes have been
updated for new version of aster calibration software.
t.ati.10m:
old cal: linear(0.001527,0.0)
from logbook entry 225, a value of 4.997 Volts (sic) was chosen
as the calibration factor for the 10m fast T probe. What this actually
represents is a cal voltage of .4997 V, using a gain of 10 degC/V,
and a filter/amp gain of 1.
The old cal factor of 0.001527 was computed as:
10 degC / V * 5V/32767 * 5/4.997 = 0.001527
So the new cal factor for the 10m probe will be:
5degC/ .4997V = 10.006 degC/V
t.ati.4m:
old cal: linear(0.001549,0.0)
from logbook entry 225, a value of 4.925 Volts (sic) was chosen
as the calibration factor for the 4m fast T. This is actually
a calibration voltage of .4925V.
The old cal factor was computed as:
10 degC / V * 5V/32767 * 5/4.925 = 0.001549
The new cal factor for the 4m probe will be:
5 degC / .4925 = 10.152 degC/V
