NSA/SKYRAD/C2 - wrong calibration coefficent for PIRd in ATQ
DataStreams:nsaskyradC2.00, nsaskyrad20sC1.a1, nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
Description:
Due to confusion over ARM calibration policy, a revised calibration was installed
and was in place for the duration of the time period indicated.  When the error
was noted, the original calibration was re-installed.

Users may notice discontinuities in PIRd data at the time boundaries of this
DQR.

Subject:
NSA/SKYRAD/C2 - Frosting and Condensation
DataStreams:nsaskyradC2.00, nsaskyrad20sC2.a1, nsaskyrad60sC2.b1
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.
