NSA/SKYRAD/C2  - Solar tracker problem.
DataStreams:nsaskyrad60sC2.b1
Description:
Beginning on 6/13, there was a problem with the solar 
tracker/shading at Atqasuk.  The observed downwelling shortwave
was not in good agreement with the theoretical value calculated 
from the direct, diffuse, and solar zenith angle, which usually 
indicates a tracking problem. The direct (NIP) data occasionally 
exhibited a stair-step pattern of dropping off slightly for a few 
minutes, then rising, then dropping off again, rather than the 
smooth increase during the hours of greater sunlight that is 
normally observed in clear sky conditions.

This problem was resolved on the morning of 6/20.

NSA/SKYRAD/C2 - 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.
