Subject:	NSA/SKYRAD/C1 - IRT incorrectly configured
DataStreams:	nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
Description:	The IRT was removed for repair and replaced with a spare that was not configured properly. Data are incorrect.

Subject:	NSA/SKYRAD/C1 - IRT incorrect min/max value
DataStreams:	nsaskyrad60sC1.b1
Description:	The values of valid_min and valid_max for field sky_ir_temp were incorrectly assigned to -49.7 and +50.0 C, respectively. The actual values should be -60 and +40 C.
Measurements:	nsaskyrad60sC1.b1: Sky Infra Red Temperature Minima(sky_ir_temp_min) Sky Infra Red Temperature Maxima(sky_ir_temp_max) Sky Infra-Red Temperature(sky_ir_temp)

Subject:	NSA/SKYRAD/C1 - IRT measurements during precipitation events
DataStreams:	nsaskyrad60sC1.b1
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.
Measurements:	nsaskyrad60sC1.b1: Sky Infra Red Temperature Minima(sky_ir_temp_min) Sky Infra Red Temperature Maxima(sky_ir_temp_max) Standard Deviation of Sky Infra Red Temperature(sky_ir_temp_std) Sky Infra-Red Temperature(sky_ir_temp)
