- 5: radiation, Site all, Fri 21-Jul-2000 14:49:41 PDT, Radiometer and soil sensor installation completed
During the period Sun, 16 - Fri, 21 July the radiometers and soil sensors were instaleed at the nine sites. The idraw file:
$ASTER/projects/EBEX00/doc/radsoil.idr
shows the relative positionig of the radiation stands and the soil temperature, soil heat flux plates and soil moisture probes relative to the rows and furrows.
Irrigation occured fairly soon after the soil probes had been installed.

Definiton of soil parameters used in soil heat flux and storage term
blkdens = dry soil mass / dry soil volume g.cm-3
gravmoist = (wet soil mass - dry soil mass)/ dry soil mass g.g-1
vmf = blkdens / mindens g.cm-3. g-1.cm3
vwf = gravmoist x blkdens g.cm-3. g-1.cm3
Cm = 0.46 cal.cm-3.degreeK-1 = 1.9 MJ.m-3.degreeK-1
Co = 0.60 cal.cm-3.degreeK-1 = 2.5 MJ.m-3.degreeK-1
Cw = 1.00 cal.cm-3.degreeK-1 = 4.2 MJ.m-3.degreeK-1
An approximate calculation of the soil volumetric heat capacity using previous
data
Cs = Cm x vmf + Co x vof + Cw x vwf MJ.m-3.degreeK-1
= (1.9 x vmf) + (2.5 x vof) + (4.2 x blkdens x gravmoist) MJ.m-3.degreeK-1
= (1.9 x 0.64)+ (2.5 x 0.01)+ (4.2 x 1.6 x gravmoist) MJ.m-3.degreeK-1
= (1.9 x 0.64)+ (2.5 x 0.01)+ (6.7 x 0.1) MJ.m-3.degreeK-1
= 1.22 + 0.03 + 0.67 MJ.m-3.degreeK-1
= 1.92 MJ.m-3.degreek-1
Crude calculation of the magnitude of the storage term, S
Typical heating/cooling is 15 degree in 12 hr (= 50000s)
If a simple linear heating and cooling at the surface occured, then:
Ht 1m2 to 5cm by 1degreeK in 1s for Cs=1.9 MJ.m-3.degreeK-1
0.05m3, 1degreeK, 1s, 1.9 MJ m-3.degreeK-1; 0.095 MJ.s.m-2
95000 J.s.m-2
Ht 1m2 to 5cm by 1 degreeK.in 1000s ....................... ; 95 J.s.m-2
Ht 1m2 to 5cm by 1 degreeK in 50 x 1000s ................. ; 1.9 J.s.m-2
Ht 1m2 to 5cm by 15 degreeK in 50 x 1000s ................. ; 27.5 J.s.m-2
............................................................; 27.5 W.m-2
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

- 10: soil, Site all, Sat 22-Jul-2000 10:10:27 PDT, Soil Sampling Schedule
A proposed soil sampling strategy and schedule:
Bulk density:
The soil bulk density should not change over time. Hence only one
measurement is required at each site. At a time when the site is dry make a
determination of the bulk densities of the furrow and the ridge soils.
The furrow soil is consolidated and bulk density may be determined using
the waxed clod method. Sometime when the site is dry, cut, with the saw,
a 0 - 5 cm deep, approximately 5 cm x 5 cm block from one of the "tiles" on
the floor of the furrow. Dry in the oven for two days weigh, wax, weigh in
air and then immersed in water. Determine displacement volume and calculate
bulk density = dry weight/ displacement volume
The ridge soil is much looser and another method may be
appropriate. When the soil is dry, take a representative sample from the
top 5 cm to fill the graduated beaker to the 100 ml level. Try to maintain
the original consolidation of the soil. Pour the entire 100 ml into a tared
Al dish. Bake for two days, weigh and calculate
bulk density = dry weight/ beaker volume
Gravimetric water fraction:
For each site make a determination of the gravimetric water
fraction for the furrow and the ridge at three times throughout the program.
Make the determinations:
when the mud is firm enough to walk on ~ 10%
when the soil is at it's driest just before irrigation ~ 5%
half-way in between these conditions ~7%
These gravimetric water fraction determinations will serve to calibrate the
soil moisture sensors installed in the soil at each site.
For the furrow soils dig out a sample using the trowel, seal in
a tupperware container, blend, take three ~30g subsamples, weigh fresh, bake
for two days and then weigh dry. Calculate
gravimetric water fraction = (fresh weight - dry weight)/ dry weight
For the ridge soils use the trowel to make a face cut, exposing
10 cm of the ridge soil, then use the scoop to obtain a represenative 0-5cm
sample. Seal in a tupperware container, blend, take three ~30g subsamples,
weigh fresh, bake for two days and then weigh dry. Calculate
gravimetric water fraction = (fresh weight - dry weight)/ dry weight
- 22: irrigation, Site all, Fri 28-Jul-2000 11:32:35 PDT, Schedule
The irrigation of the field started 28/07 at the North end.

After having the 20A,220 array breaker blow again, we decided to replace
it with a 30A size. The 8kVA transformer can handle >33 according to
Kurt and the distribution cabling is 8Ga. to there and 10Ga. from there.
We had been running too close to the edge and the increased inefficiencies
due to the heat and investigators periodically plugging in new loads
push us over the edge. The 2nd breaker pop occurred in conjunction
with the trailer air conditioning coming on; no doubt sagging the voltage
to the array, and thus more current.
Wed, 8/2 Fuse blown:
In the main array 8kVA distribution transformer's LEA/Dynatech Surge Arrestor.
It is a 30A,125V fuse which is on one of the 2 legs of the 220 input.
The load to the #7 array includes the air-conditioner and it is possible
that caused the failure. There is likely an imbalance on the 2 legs
which has not been fully measured.
The fuse was replaced and the power came back up apparently without problems.

Bayreuth - Site 7
CSAT+krypton, fast-T ingested by Thomas' PC only.
Thomas' logger not connected to aster. Continuing problems
with reliable ingest on serial channel forced him to move it
to his PC. We will merge his data later. Ditto for Heiping's data.
KNMI - KD5cm + krypton (only locally stored by KNMI)
Kearny - Mostly deployed. Still need to add IR temps and change some
thermocouples to measure leaf temps (now just stem)

After kludging channels for Psp.in and Psp.out last night, the
data appear consistent for the most part but the Psp.in had some
bad periods overnight suggesting that the mux may still have a
problem (ie maybe it was working in the cooler temps and the
rewire only works in heat...)
- Most boom angles have been shot yet.
- We must clean all kryptons and aster rad sensors soon.
- Tsfc*4 still needs to be installed at 8

A quick EBEX update for Tom.....
The EBEX00 project operations phase began with an irrigation cycle of
the cotton field progressing from the north to south over a period of
6 days. Immediately before operations began, the network was
reconfigured from its initial intercomparison configuration. The
field is now dry but another, and final irrigation cycle of the season
begins Saturday.
Some difficulties were experienced with the adam power distribution
after all of the various systems were installed. Initially all adams
and user equipment were supplied off a single 220VAC, 20Amp circuit.
After a few trips of the circuit breaker in the base, a 30Amp unit was
installed. A subsequent blown fuse in the main distribution
transformer's surge arrestor encouraged a reconfiguration with one
tower site being moved onto a second 20A circuit from the base. After
this move, all of our power problems have gone away. Some of our
difficulty may have been associated with wide scale problems
experienced in California during the recent heat-wave in which network
brown-outs and service interruptions occurred throughout the state.
At this writing, essentially all NCAR sensors are working. One sonic
is reporting questionable data and the 'repaired' sonic needed to
replace it was D.O.A. and had to be returned to ATI. A bad PAM soil
moisture sensor cannot be replaced without a spare. A few lingering
radiometer problems were fixed shortly after operations began. The 4
component infrared 'canopy' temperature sensors have been installed
and two sets of gravimetric and bulk density soil moisture samples
have been taken. Steve Oncley's soil and plant temperature sensor
network is being built and should be installed at 16 sites throughout
the field within a week.
In addition to the complement of NCAR sensors, some of the European
loggers and sensors are being ingested directly by Aster, but not all.
2 Csat sonics from Basel are being monitored in addition to their 4
other sonics being acquiring separately. The Hong Kong University
data are being recorded on Heping's laptop including 2 Csat sonipcs, a
Krypton, Vaisala-T, and thermocouples but not on aster. He has only
been able to acquire data at 10hz. Continuing difficulty with serial
communications has precluded ingest of the Bayreuth Csat, Krypton and
fast-T sensors. RMYoung and Metek sonic data are being ingested by
Aster. Gordon wrote java scripts to merge, display and archive data
for Thomas Foken and Heping. He wrote another java script to extract
NCAR short-wave radiometer data for Roland to intercompare with his
Basel radiometers. KNMI is storing their own KD5cm, and krypton data
locally. The Kearny site is mostly deployed including as of this
writing the IR temps. They still need to adjust some thermocouples to
measure leaf temps. The Kearny site is powered by 220VAC from aster but
records all of its data locally.
A low speed network connection to the base is possible. Gordon setup
a locally initiated automated script which dials into the ISP and establishes
a 9600bps link accessible to ATD. The link can be used for sporadic
code updates and short data transfers.

I wrote a bit of code in: aster/isff/src/sfun/EBEX00/radcomp.q
to compare the Rsum and Rnet values. A plot over the last 4 days is
attached. Red lines are Rnet, Green Rsum using PSPs, and Blue Rsum using
K&Zs.
The nighttime Rsum values use just PIR data and are larger by ~20% than
Rnet values.
The daytime Rsum values usually are larger than Rnet over cotton (and smaller
over dirt!). Confounding this study is whether the domes are dirty. Stn7
at least, was cleaned 2 days ago, which appears to have increased the magnitude
of the K&Z somewhat. In general, the K&Zs read a bit higher than the PSPs.

- 138: soil, Site all, Mon 04-Sep-2000 09:12:06 PDT, soil water fraction and bulk density
Evolution of the gravimetric water fraction and the bulk density after irrigation.
The gravimetric water fraction and the bulk density of the soil one day and three days after irrigation were measured. The methodology used during EBEX to determine the bulk density of the soil, either by using the wax method for the furrow, either by filling up a known volume for the ridge was unsuitable for the field in a short period of time after irrigation.
A new methodology was used. I've borrowed some containers with a known value from David Grantz, University of California, and applied at a site South of Station 9 one and three days after irrigation.
The containers were made of metal, with a 10.16 cm diameter and a 7.62 cm high (4'x3'). With that dimensions it was not possible to sample soil from a 0-5 cm but from a 0-7.62 cm depth.
The method consisted in inserting the container into the ridge and furrow soil. The amount of dirt that was collected was then placed in the oven for two days. After the drying period, the container was weighted and the bulk density could be determined.
A major inconvenient of this method was that when the container was being inserted in the soil a bubble appear between the container bottom, that was up at the moment, and the soil. One solution to minimize the appearance of the bubble was to slightly move the container obliquely when it is being punched into the soil.
This method was used only at this site. There were no changes in the measuring procedures at the other stations.

not status, log, etc.
7-25-00 17:30 GMT: cleaning of all radiometer domes at stand site 09.
check of level. All ok, except NCAR upward looking
pyrradiometer is only a little bit out of center.
nothing adjusted.
cr23x uni basel: time incorrect.
7-28-00 18:10 PDT: John rewired stn1 logger so these signals now look okay.
07/31/00 13:33 PDT:
The Kipp&Zonnen has been providing bad data through the night and
into the day. During the day after warming up, the data has been
OK. The wiring inside the ventillation plenum had a bad connection.
It was recabled and now appears OK.
The wiring arrangement for the K&Z radiometers needs to be improved.
7-30 16:00 - 16:15 GMT Cleaning of all domes at radiation stand site 09.
Dome of Q*7 of NCAR is dirty, especially at lower parts.
probably due to spraying. Completely cleaning was not possible.
Time Uni Bsel OK. Leveling of all instruments OK.
8-5 18:19PDT: The Rsw.in and Rsw.out may have been temporarily fixed.
These have never been right at this site since setup.
The Rsw.out looked like an 'in.'
The Rsw.in was basically garbage/missing.
Checked:
Wiring: consistent w/ Comments in logger pgm list..ie correct.
Msg Out: both aster prep and logger prm listing consistent..ie correct.
CR10 pgm: appears correct as best I can tell.
Possible Mux problem in logger box, or else pgm is actually incorrect.
It appears that the cr10 is sampling these on AM416 mux channels
3-L/H, and 4-L/H instead of 4 and 5. This implies we either need
another 'pulse port 2' to move the mux forward to the correct channels,
or else the thing is sticking on 1 channel.
Temp fix = plug Rsw.out cable into the 'in' port on the box which goes
to 4-L/H. Jumper plug 'Rsw.out' port on the box to 3-L/H
and plug Rsw.in cable to the 'out' port.
I presume the coefficients are being applied correctly in the program.
Keep an eye on it to see if we're OK, and maybe try that program step
also.
Radiometer Cleaning cycle:
st1 8/8 ~23Z
st2 8/9 ~0Z
st3 8/7 ~22Z
st4 8/9 ~0Z Q7 has those darn spots...
st5 8/7 ~21Z were in good shape.
st6
st7 8/6 ~0Z The Rsw.in/out definitely needed it but not extreme.
The Q7 had spots on it probably from spray?
Also cleaned the German's sensors.
st8 8/6 ~23Z Rsw.in/Rlw.in did need it but not extreme. Q7 spots
seemed to come off pretty well.
st9 8/6 ~20Z The Q7 had the worst spots seen so far. Cleaned
them some but not completely off.
8-6 19:00 PDT: s8
The Psp.out has been giving bad readings.
It appears to be a connection or the Eppley photopile
is bad.
8-7 15:19 PDT The TSFC probes at station 8 are working now.
The wrong calibration factors were used.
8-7 16:47 PDT: The Rsw.out (s8) sensor is working now.
It was another case of bad wiring inside the ventillation plenum.
8-8 11:20 PDT: Rsw.in and Rsw.out at site 7 looking good
Another program problem. The multiplexer was
not skipping forward 2 steps. The heat may have had
something to do with it. I added delay commands between
the increment commands. That seemed to fix it.
8-11 10:01 PDT: KZ at station 6 removed
The problem with the KZ seems to be in the
sensor so I brought it back to the base. I
was out there at the site from 9:20 - 9:40
local time.
8-11 10:24 PDT: KZ fixed at station 6
The KZ at station 6 is back up, ~10:40 local. The
internal connector was bad. removing the shrink tubing
near the connector fixed the problem so I left the
connector in place. My guess is the contacts between
male and female have opened up and little bit of twist
on the cable causes and open circuit.
8-14 17:29 PDT: Clean domes & krypton at 3
Due to the move the domes and krypton needed cleaning.
This was done at ~17:15 local.
8-16 11:32 PDT: rads cleaned s7
While Thomas was cleaning his radiometers at s7, he offered to clean ours
as well. He noted that the Q7 was rather dirty, but the others seemed okay.
8-21 10:08 PDT Dome and Krypton cleaning
Today is dome and krypton cleaning. All nets had a fine
layer of dust on them. The glass domes looked good.
Kryptons had minimal contamination.

- 142: radiation, Site all, Tue 31-Oct-2000 09:52:06 MST, Campbell coefficients
Post-EBEX00 the integrity of the Campbell coeffs was checked.
Consistency in the sequence:
CalLab data | Coeffs in LabView loading files | Coeffs inspected post-EBEX
was examined and found to be correct. See delany/deployments/ebex00/coefftab.fm
There was an apparent discrepancy which was resolved. The coeffs in Campbell
St7NW were not loaded in the memory, but rather were embedded in the code.
This circumstance probably occurred because originally there were only
eight Campbell 10X's available and one Campbell 10. The Campbell coefficients
need to be loaded in the code as the memory for the Campbell 10 is volatile.
Then an additional Campbell 10X was acquired and allocated to St7NW.
The original code was retained. This would cause no problem, although it
did cause puzzlement.
Neither JM nor SS (nor anyone else) changed coefficients in the field.
However, JM did find and correct (see LB# ????) cable misconnections.
JM did find and correct (see LB# ????) wiring shorts
SS, did adjust multiplexer delays (see LB# ????)
- 143: radiation, Site all, Tue 07-Nov-2000 15:21:38 MST, Radiometer coefficient checks,flagged bad data
Inspection of the coefficients indicated that the correct coefficients were
used throughout the deployment.
The procedure of checking coefficients is described in the file:
delany/deployments/ebex00/coefftab.fm
and involved checking the coefficients throughout the sequence:
cal lab data
coefficients listed in LabView coefficient Campbell loading files
manually cycling through the memory of the Cambpbell after return from EBEX00
The problem data resulted from wiring breaks and the bad data is to be
flagged but not corrected.
This flag file is formed by defining when the value of the output of an
individual radiometer deviates significantly (say 20%) or more than
20 Wm-2 from the value of a credible reference radiometer.
These reference short-wave down-welling and short-waveup-welling radiometers
were chosen by inspecting the traces of all the radiometersfor reasonable
and continuous data.
For the Rsw.in radiometers the four traces were examined to define which
was the most continuous.
Rsw.in 9 is taken as that credible reference radiometer.
For the Rsw.out radiometers all 15 traces were examined to define which
was the most continuous.
Although 3, 4, and 5 had fairly good continuous traces the best was chosen.
Rsw.out 4 is taken as the most credible reference radiometer.
- 144: radiation, Site all, Tue 07-Nov-2000 15:24:49 MST, Dome cleaning and calc of Rsw.in/out values
The dome cleaning procedure during EBEX was not as systematic as
could have been wished. A summary of dome cleaning undertaken during
EBEX00 was made and listed as Logbook# 139. Plots of the radiometers'
responses were made and inspected.
There were four up-looking short-wave radiometers:
Station 7 unventilated Eppley PSP -> Rsw.in 7
Station 7 ventilated Kipp & Zonen -> Rsw.in.kz 7
Station 8 ventilated Eppley PSP -> Rsw.in 8
Station 9 unventilated Eppley PSP -> Rsw.in 9
As the four radiometers viewed the identical sky the are redundant and
a single value of Rsw.in is all that is required. Inspection of the
traces for the four were made to decide how best to generate this single
trace of Rsw.in
The effect of cleaning had noticeable effects on
Rsw.in.kz 7 on 16 Aug of ~ 50 Wm-2
Rsw.in 8 on 21 Aug of ~ 80 Wm-2
other cleaning events did not make much difference in radiometer response.
The other two up-looking short-wave radiometer yielded more consistent traces.
with Rsw.in 7 ~ 1.04 X Rsw.in 9 .
I propose to use for the the single value of Rsw.in
Rsw.in.mean <- (Rsw.in 7 + Rsw.in 9)/2 for the period 6 Aug - 23 Aug
when both thes radiometers had good output, and
Rsw.in.mean <- (Rsw.in 9 X (Rsw.in.mean/Rsw.in 9) for the period before
6 Aug when only Rsw.in 9 had good output
In general the dust from the traffic along
the dirt road together with the effect of agricultural aerial spraying
was more apparent on the up-looking radiometers than on the down-looking
radiometers.
There were fifteen down-looking short-wave radiometers:
Station 1-6 unventilated Eppley PSP -> Rsw.out 1-6
Station 1-6 ventilated Kipp & Zonen -> Rsw.out.kz 1-6
Station 7 unventilated Eppley PSP -> Rsw.out 7
Station 8 ventilated Eppley PSP -> Rsw.out 8
Station 9 unventilated Eppley PSP -> Rsw.out 9
Each of these radiometers viewed different surfaces although the paired
Eppley and Kipp and Zonen radiometers at the six station, stn1 - stn6 could
be assumed to have had a very nearly identical view.
The ratio of Rsw.out/Rsw.out.kz for stations 1-6 were:
(1) 1.076, (2) 1.08, (3) 0.975, (4) 1.07, (5) 1.065, (6) 1.04, or (1-6) 1.05
The value taken for each of the up-welling short-wave radiation should be the
mean of the Eppley and the Kipp 1and Zonen Radiometers.
The value for the other three stations should be the value of the single
radiometer at that site.
