261: Status, Site none, Wed 19-Jun-2002 09:59:18 CDT, status, June 19
Daily Status, Wednesday, June 19
Looking at past 2 days, ending at 0900 CDT.

Staffing: Militzer & Semmer

Recent maintenance:
s7: visit yesterday to download SDR data
s2: install SDR system at 2
s1: fix GOES problem late yesterday

Anomolies:
s5,6,9 now have single-level Qsoil profile outages
s6 krypton noisy (GOES?)
s7 krypton still low variance
s6&s9 should have UW sonics

s5 : down at ~3:00CDT, came back to life around 7:00CDT

250: Radiation, Site none, Sun 16-Jun-2002 10:30:53 CDT, Net Radiometer Q99258 repaired
The net radiometer Q99258, which had been removed from site 2 on 13 Jun''02,
 was repaired and replaced in the spare sensor pool.
The upper dome had been dimpled by heavy rain or hail. It was replaced with
 a new dome from the cache of net radiometer domes in the base.

176: Site_visit, Site none, Sat 01-Jun-2002 21:43:04 CDT, Site 10 visit
Arrived at site 10 1/2mile west and 2 miles north of site #3, at 18:40

Obtained some dubious clods.

Leveled the radiometer

Departed at 19:10

13: EVE, Site none, Wed 24-Apr-2002 18:08:47 MDT, Serializer / SlowAD VDC Check
Serializer and SlowAD were checked against a 'dial-a-volt' reference
for consistency.

Reference: 2.3995  (based on 4.5 digit dvm.  output varied slightly
		    between boards from about 2.3993 to 2.3998)

A/D Values reported are nominal of what was observed.
A/D Consistency: The 4 channels on each pmb-ad board were consistent within a
		few counts between the channels and between readings.
Serializer Values: The measurement was that reported by EVE after scaling of
		the raw readings.  These include the divide-by-2 cable used
		to scale the krypton voltage and represent mV.
		Note that for every unit, the nominal values shown had
		noise of about "1" mV total during the brief test.
Serial Numbers:	Dash numbers represent the residual reference voltage reading
		taken by Steve Oncley used in adjusting the output.
		For example"-07" represents 2.5007, "-93" represents 2.4993.
		PMB boards were tagged "A1" and "S1", etc.

Note 1) Station 1 was sitting in the cal-lab adjacent to the running
	co2 system.  There was quite a bit of noise on the a/d counts
	while taking the readings inside to box there.  The readings were
	roughly 23740/23770 and were changing by up to 100.  The readings
	shown above were taken in a different box in a different location
	and the a/d counts were extremely consistent.  I did not repeat
	the testing to determine whether the noise was endemic to station
	1's box or not.   Note that the readings for station 8 were taken
	in the same location.
