Subject:
NSA/SKYRAD/C1 - Frosting and Condensation
DataStreams:nsaskyrad20sC1.a1, nsaskyrad60sC1.b1, nsaskyradC1.00
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.
