NSA/SKYRAD/C1 - IRT measurements during precipitation events

Description:
The IRT measurement of sky/cloud temperature was in question during
precipitation events because rain or snow could accumulate in the
upward-pointed lens barrel. This was corrected by reorienting the
IRT to measure the sky temperature as reflected by a gold mirror.

NSA/SKYRAD/C1 - itermittant IRT bias
DataStreams:nsaskyrad60sC1.b1
Description:
A problem with the SKYRAD IRT that itermittantly produced a gradual increase in the sky 
temperature measurement then a sudden correction, as compared to AERI, appears to have been 
caused by a combination of a failing IR detector, a poor signal cable, a contaminated 
(with condensation or frost) mirror or lens, and low ambient temperatures. The positive 
bias was apparently not consistant in either frequency or duration but on days when the 
unusual behavior is observed, it usually occurred from about 00:00 to 06:00 local time. 

The instrument was repaired and recalibrated and the signal cable replaced.

NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1, nsagndradC1.00
Description:
During the power outage the upwelling global measurement from the PSP instrument shows a 
slight increase from -5 to +0 W/m2.  This is due to removal of thermal offsets induced by 
the AC heater during the power outage.  This heater is installed within the PSP 
ventilator - it is necessary for the NSA/C1 climate.
The upwelling longwave PIR instrument is unaffected due to case and dome temperature 
corrections.
The IRT is AC powered and was not operational during this time period.

NSA/GNDRAD/C1 - Reprocess: Longwave Calibration error
DataStreams:nsagndrad60sC1.b1
Description:
Modified pyrgeometer calibration procedures were implemented beginning in December 2003.  
These modified procedures introduced a calibration bias in the longwave data.  The 
previous procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations.                                                             
                The data collected while the incorrect procedures were in place are 
being reprocessing to remove the calibration bias.  Note, this also affected standard 
deviation, maximum and minimum data fields.

NSA/SKYRAD/C1 - Instrument cleaning effects
DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
Starting Dec 16th the Skyrad PIR1 and PIR2 (down_long_hemispheric)started differing by 
greater than 30W/m2 at times.  This is much greater than expected  for these instruments 
(typical is <10-15 W/m2).  NSA OMIS reports and observer comments reveal that PM 
periodically clean the snow from the IRT and ventilator fans on Skyrad and Gndrad.  In the case of 
the Skyrad PIRs, one lies in the wind shadow of the other and builds up more snow which is 
periodically cleaned out and then builds up again causing the PIR1 PIR2 discrepancies.

Disregard down_long_hemispheric during this time period. However, data suggests PIR2 is 
most likely at fault - potentially use PIR1 data during this time period.

NSA/SKYRAD/C1 - IRT mirror heater failure
DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
The heater of the IRT gold mirror failed due to a broken wire (that probably occurred on 
12/13 during maintenance of the solar tracker) allowing snow and frost to accumulate on 
the mirror until it was cleared during daily preventative maintenance. The problem was 
corrected when the heater wires were replaced.

DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
The short_direct_normal (NIP) instrument and cable were damaged by tracker rewind 
malfunction. Tracker and NIP replaced on 4/22 2200GMT but tracker not operational until 4/23 
1815GMT.  Thus, down_short_diffuse_hemisp (8-48) was not shaded 4/22 to 4/23.

Do not use 8-48 data from 4/22 to 4/23. NIP data is not recoverable during entire time but

diffuse)/cos(zenith angle)

NSA/GNDRAD/C1 - Upwelling PIR ventilator fan failure
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1
Description:
The PIR exhibited a positive bias of approximately 6 W/m2 compared to the upwelling IRT 
due to ventilator fan failure.  Thus, the up_long_hemisp, data stream is high by about 6 
W/m2.    
   
Bias is not consistent and depends on atmospheric conditions. Either disregard the 
up_long_hemisp data or use the IRT for an estimate of the up_long_hemisp values during this time 
period.

NSA/GNDRAD/C1 - Net radiometer removed
DataStreams:nsagndrad60sC1.a1, nsagndrad60sC1.b1
Description:
The net radiometer was removed from the NSA.C1 GNDRAD instrument suite on Feb 3, 2000.  
Net rad variables were filled with garbage data until Sept 23, 2000 and with missing values 
(-9999) until 20041103.  The net rad variables were removed from the netcdf files after 
20041103.

A reprocessing task (RID-526) has been submitted to the queue to address the need to add 
metadata to the NSA.C1 GNDRAD netcdf files documenting the missing data as well as to move 
toward a consistent datastream format throughout time.
