Subject:
NSA/SKYRAD/C1 - IRT measurements during precipitation events
DataStreams:nsaskyrad60sC1.a1
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.a1:
  • Sky Infra-Red Temperature(sky_ir_temp)
  • Standard Deviation of Sky Infra Red Temperature(sky_ir_temp_std)
  • Sky Infra Red Temperature Maxima(sky_ir_temp_max)
  • Sky Infra Red Temperature Minima(sky_ir_temp_min)

Subject:
NSA/SKYRAD/C1 - IRT insufficiently heated
DataStreams:nsaskyrad60sC1.a1
Description:
IRT had insufficient heating to maintain an internal reference temperature above 0 degrees 
C. Measurements of sky temperature were over-estimated when instrument was below 
freezing.
Measurements:nsaskyrad60sC1.a1:
  • IRT1 maximum(irt1_max)
  • IRT1 standard deviation(irt1_sd)
  • IRT1 minimum(irt1_min)
  • IRT1 mean(irt1_mean)
