Subject:	NSA/SKYRAD/C1 - IRT removed for repair
DataStreams:	nsaskyradC1.00, nsaskyrad60sC1.a1
Description:	The instrument was damaged by internal water condensation caused by the exterior foam insulation used to keep the IRT above freezing. It was returned in July 1998 to the manufacturer for repair.
Measurements:	nsaskyrad60sC1.a1: IRT1 maximum(irt1_max) IRT1 standard deviation(irt1_sd) IRT1 minimum(irt1_min) IRT1 mean(irt1_mean) nsaskyradC1.00: Raw data stream - documentation not supported(Raw data stream - documentation not supported)
