Subject:
NSA/GNDRAD/C1 - Reprocess: IRT insufficiently heated
DataStreams:nsagndrad60sC1.b1
Description:
IRT had insufficient heating to maintain an internal reference temperature above 0 degrees 
C. Measurements of surface temperature were over-estimated when instrument was below 
freezing.

Data will be reprocessed, but users can correct data using the following correction 
factor:

If T_reference < -5°C, then

  IRT_corrected = (IRT_original - 32.993K)/0.87238

where T_reference can be estimated with the ambient temperature (e.g. 
inst_up_long_hemisp_dome_temp or inst_up_long_dome_temp)
Suggestions: 
Measurements:nsagndrad60sC1.b1:
  • sfc_ir_temp
  • sfc_ir_temp_std
  • sfc_ir_temp_min
  • sfc_ir_temp_max
