NSA/SKYRAD/C1 - reprocess: PIR identified as unshaded is really shaded
DataStreams:nsaskyrad20sC1.a1
Description:
On 5/15/02 the Global PIR was moved from the unshaded
position on the Skyrad stand to a shaded spot on
the tracker.  It is still using the same Logger
channel as it did as an unshaded PIR even though it
is now shaded.

Description:
The operators in both Barrow and Atqasuk reported significant ice buildup during nights 
for the period specified, with the ice melting during the days. This condition is reported 
in preventative maintenance reports as continuing until on or near 5/18/2004. However, 
review of data shows no discernable radiometer icing.

NSA/SKYRAD/C1 - Datalogger grounding problem
DataStreams:nsaskyrad20sC1.a0, nsaskyrad20sC1.a1, nsaskyrad60sC1.b1, nsaskyradC1.00
Description:
Both PIRs reported unreasonable high readings with coincident low reading from the IRT. 
Since both PIR instruments exhibited exactly the same behaviour and the IRT an opposite 
response during large suspect data excursions this indicates that the false signal maybe the 
result of poor grounding. 

The PIR1,2 data and the IRT data are most adversely affected.  During the problem periods 
PIR irradiance increased (typ pos 200-300W/m2) while the IRT response was negative (typ 
neg 20-30W/m2) but followed the response of the PIR.  The Skyrad shortwave instruments 
were also affected but to much less extent (within their uncertainties).  Data quality flags 
are typically not triggered during these problem periods.

Data logger grounding was improved on 6/10 2005.  The problem hasn't re-occurred since 
that time.

NSA/SKYRAD/C1 - Reprocess: Incorrect datalogger program affecting PIR1 and PIR2 
downwelling longwave
DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
The excitation delays using in measuring the PIR1 case thermistor commonly named "Case1" 
and the PIR2 dome thermistor called "Dome2" were discovered to have been incorrectly set 
to 0 in the Skyrad datalogger program when the new CR23X based Skyrad loggers were 
installed.  The result of no delay in these measurements results in an error in the measured 
resistance of the thermistors, Case1 and Dome2 and thus the calculated PIR1 and PIR2 
irradiances.  The errors are inversely proportial to temperature.

Users can apply the temperature dependent irradiance corrections shown in the table below. 
 Recall that the reported uncertainty of PIRs is typically +-.25% to +-.5% or 1 to 2 
W/m2.  The error corrections become the same order of magnitude or larger than the 
instrument uncertainties at or below 260K or 9F.

NSA/SKYRAD/C1 - Power outage affecting some SKYRAD instruments
DataStreams:nsaskyrad20sC1.a0, nsaskyradC1.00, nsaskyrad60sC1.b1
Description:
During the power outage the downwelling global measurement from the PSP instrument and 
downwelling diffuse 8-48 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 downwelling 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/SKYRAD/C1 - Instrument noise
DataStreams:nsaskyrad60sC1.b1, nsaskyrad20sC1.a0
Description:
Skyrad data appears affected by noise creating bias in analog voltage readings on 
02/15/2006 from 1300-1800GMT and again on 02/16/2006 from 1300-1500GMT.  The second night the 
noise is attenuated significantly.  By 02/17 no bias/noise is detectable. The thermistor 
measurements in PIR1 and PIR2 were unaffected during these excursions and showed no 
deviation from normal during the problem period.  In addition, the onboard logger temperature and 
battery voltage read normal throughout.  The problem has not reappeared as of 4/25/2006.

Description:
Installed Skyrad PSP (downwelling shortwave hemispheric irradiance) had calibration

PSP #32026 should use RSc@45=8.7578 ?V/W/m? and not Rs@45=8.6335.

Reprocessed to correct downwelling shortwave hemispheric irradiance (DS) by:

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

corrected when the heater wires were replaced.
