Subject:
NSA/GNDRAD/C1 - IRT removed for testing
DataStreams:nsagndrad60sC1.a1
Description:
The IRT instrument was at PNNL for cold temperature modifications and testing. Instruments 
returned for the summer season. Data collected after the instrument return looks 
reasonable. 

IRT data recorded during the period the instrument was removed is bad.
Measurements:nsagndrad60sC1.a1:
  • IRT1 standard deviation(irt1_sd)
  • IRT1 mean(irt1_mean)
  • IRT1 maximum(irt1_max)
  • IRT1 minimum(irt1_min)

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/GNDRAD/C1 - IRT insufficiently heated
DataStreams:nsagndrad60sC1.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:nsagndrad60sC1.a1:
  • IRT1 standard deviation(irt1_sd)
  • IRT1 mean(irt1_mean)
  • IRT1 maximum(irt1_max)
