CASES99: Radiation Messages: 25 Entries..

This information has been transcribed from my CASES97/99 field notebook.
At tear-down I went around the four surface radiation sites and removed
the radiometers and the soil sensors. I made field notes at the sites.
The notes were made on Saturday, 30 Oct''99, or possible the next day.

The ten pyrgeoemeters used during CASES99 were set out in two configurations:
 the intercomparison with the pigs mounted side-by side, all up-looking,
 the measurement with the pigs dispersed to their specific location; 
   two up-looking at 50m on the tower boom,
   two down-looking at 50 m on the tower boom,
   two uplooking at 2m, one at station 1, one at station 2,
   four down-looking at 2m, one at station 1, one at station 2, 
                         one at station 3 and one at station 5.
The parameter identifications corresponding to these two configurations are:

The pyrgeometers were in intercomparison configuration:
 1999 September 25, ??:00   to  1999 October 4, ??:00
The pyrgeometers were in measurement configuration :
 1999 October 4, ??:00      to  1999 October 30, ??:00

At 1030 Wed 8 Dec''99 I temporarilly depowered the fans to allow a full 
snow cover over all the pyrgs.
It started to snow in the nightime and although the fans had kept the dome 
clear snow had built up on the shield so that the snow formed an annulus 
higher than the top of the domes.
Snow is forecast to continue for the next 24 hours 

The extra snow did not occur, the existing snow on the domes evaporated.
On 9 Dec at 11-30 I restarted the fans and cleaned the domes.

The boom pigs' data has been plagued by intermittent spikes
Today, at ~1030 I replaced the serial cable from the boom-box Campbel 
to the serial BOB with a new one. This seems to have cured the problem.
At ~1700 I removed all the snow from the radiometers and cleaned the domes.

These are the coefficients determined from the oil-bath temp calibration of 
the pyrgeoemters, prior to the CASES99 deployment. These coefficients were 
used during the pre-CASES99 intercomparison in the field and during the 
deployment. They are also to be used for the post-CASES99 intercomparison 
on the roof at the Foothills Lab.
This logbook table was copied from 
/net/sssf1/delany/deployments/cases99/lwdiverg/lbpigcoeff.txt
and then the non-pyrgeoemetrs coefficients were added

NOTE!

The campbell loggers on the PAM stations transmit at 1200 baud.
They were set this way in the field at CASES99 after the 
intercomparison period.

Between 1030 and 1100 the radiometer domes were cleaned at Stations 1, 2, 5 and 3. All the fans were operating smoothly

At ~ 1530 on 26 October the 50 m trolley was pulled in and the four radiometers'
domes were cleaned with water wetted tissue. There was indication of brown dirt
on the domes.

Between 1030 and 1115 the radiometer domes and the net radiometers were cleaned at Stations 1,3, 5 and 2. Photographs of the ground surfaces under the radiometers were taken.

Between 1230 and 1300 the domes of the radiometers at stns, 1,2,5 and 3
were cleaned

At  11:15 the domes of the radiometers at station 1 were cleaned
At ~13:00 the domes of the radiometers at stations 2, 3, and 5 were cleaned.

There were traces of brownish grey dust, especially on station 1 domes

All net radiometers were cleaned.
All fans were running. The fan at station 3 was noisy.

We retracted the 50m radiometers and cleaned them, beginning at 1500 CDT,
Oct 18.  They were cleaned with "de-mineralized" water and kimwipes.

The radiometers were returned to their outboard position at 1615 CDT
(after unfouling the hauling line with the loooon green hook).

The domes of the surface radiation sensors were also cleaned after 
finishing the tower radiometers.

The pyg.out pile was bad so I went out to look at it.
According to Tom, this problem has happened before.
The voltage going to the multiplexer board was varying
quite a bit. I played with the connector inside the Campbell
which resulted in a good signal. The cables had been reversed
from a previous test so I switched them back to the correct
configuration. Will need to monitor to see if fix works. If
so, we will need to flag this Campbell box for repairs.

The Rpile.out data has been intermittent at station 2.  At 3:50 pm,
local time, Oct 12, I disconnected and reconnected the cable at the
sensor and this appeared to solve the problem.  At that time, I also
bumped the Schwartz out of level by popping the leveling screws out
of their upper seats.  I reseated the screws and found that the level
was still okay.  At that time I also adjusted the level of the net
radiometer about its N/S axis.

The Rpile.out data soon failed again and at 5:34 I swapped the pile.in
and pile.out cables at both ends.  This fixed the problem again.

I inventoried the surface radiometers to investigate the cause for
some anomolous long wave data:

Station	Rnet	Pyg.in	Pyg.out	Psp.in	Psp.out
 1	97034	29260	26416
 2	94197	31977	31981	940181	940187
 3	94125		31975
 5	97035		31979

This showed that the radiometer arrays on stations 1 and 2 were
interchanged when deploying them at the end of the intercomparison
period.  This morning (Oct 8) we entered into the CR10 loggers at 
stations 1 and 2 the coefficients corresponding to the radiometers 
mounted there.

WARNING  WARNING  WARNING  WARNING  WARNING  WARNING 
Be aware that the labeling of the radiometers at stations 1 and 2 
is different for the intercomparison than it is after the radiometers 
were deployed at the various PAM stations.
WARNING  WARNING  WARNING  WARNING  WARNING  WARNING 

The coefficients for the PSPs at station 2 were entered around 9:30
am local time.  
The coefficients for the PYGs at station 1 were entered around 10:55
am local time.
The coefficients for the PYGs at station 2 were entered around 11:10
am local time.  At that time we found that the signal cables for the
two PSPs were interchanged and this was corrected at the CR10.

At station 5 we found a small error in the third coefficient of the
Tcase.pyg.out calibration.  The data sheet lists a coefficient of
-6.90295 and the CR10 has a coefficient of -6.9229.  It was decided
to leave this coefficient as we found it, since this value was used
during the field intercomparison of the radiometers.

Rnet calibrations from REBS 8/17/99 calibration are:
	Positive Negative (Zero Wind CF in W/m2 mV)
94196	9.25	11.44
97035	9.28	11.54	stn5 (stn5 is using these values)
94197	9.07	11.25	(stn2 is using these values)
91096	8.54	10.59
94125	8.65	10.75	(stn3 is using these values)
97034	9.31	11.39	stn1 (stn1 is using these values)

Stuff done today:
stn1: changed CR10 baud rate to 1200.  Commands are:
	*0 
	7H 
	*1 
	A (until step 62)
	51 (overwrites 52)
	*0
	(this can be done through EVE by typing:
	entersys	
	stop
	talk (port 4, rate 9600, etc.)
	start
	Rnet is Q97034
stn2: moved solar panels; hooked up battery swiped from stn5; mounted Rnet
	with 2 screws (only had one before); leveled Rnet; added connector
	to bare wires from Rnet so it could plug in; changed baud rate to 1200.
	Rnet is labeled "station2"
stn3: moved solar panels; moved rad stand from IC array; leveled and oriented
	stand; mounted Rnet from box labeled "station3", but with a label of
	"station1"!  Found that fan cable wires were color-coded backwards, so
	rebuilt this cable (red negative, black positive); changed baud rate
	to 1200.
stn5: stole battery from main station to power radiometers at stn2; removed 
	wrong DC power cable; attached good DC power cable; cut cable ties;
	changed baud rate to 1200.
	Rnet is Q97035.
All rad stand solar panels are now located about 4m to the NE of the CR10 box,
	with the CR10 on the East side of the rad stand.

Installed 48m boom about 1300 today - leveled to within 0.003 deg.  The
pull rope is tight!  Also, don't trip over the CR10 box on the floor 
at 49 m.

Mounted radiometers at stns 5, 2, and 1 (in that order), but not reporting yet.
stn5 is down waiting for a power cable/solar power move and baud rate change.
stn1 is waiting for a baud rate change
stn2 is waiting for a new battery!
stn3 is waiting for the whole rad stand to be moved.

Just cleaned domes on all pygs in the IC array.  They all were somewhat
dirty.  Also checked levels and all were good.

Everest IRT Swapped:
Sensor 3577-4 removed; sensor 3577-2 installed

After the thunder/rain storm 2 nights ago the old sensor
was reading 100 deg-C.

Here is a first cut at adjusting biases on Rpile from the radiometers
based on data from the interval "99 Sep 25 17:00",lenhr=31,stns=0:

Rpile.in.a.boom Rpile.in.b.boom Rpile.in.s01 Rpile.in.s02 Rpile.out.a.boom 
              0             0.5         -1.2          bad             0.7
Rpile.out.b.boom Rpile.out.s01 Rpile.out.s02 Rpile.out.s03 Rpile.out.s05 
             0.4            -1           bad           0.2            10

I just used the small bubble level to check the levels.  Most looked okay,
though I adjusted the western 2 and the eastern 1 a bit.

The pyrgeometer intercomparison can be considered to have officially
started at 12:15 (1715 Z) today.  Yesterday, Tony mounted fans on
all housings.  Today, I just connected the radiometers which were
recalibrated (after their swim in oil) and received here last night.
(It was necessary to reposition both radiometers on their 8-hole base
plates to fit the housings.)

I also just leveled all of the Schwartz's (not knowing if this had
been done already) using the old digital level.  Obviously, I didn't
have a good reference surface, but I still think that I got them
to within 0.1 degree.  (They all sight to the horizon similarly.)
