FKB/SKYRAD/M1 - Instrument setup incorrect data
DataStreams:fkbskyrad20sM1.a0, fkbskyrad60sM1.b1, fkbskyradM1.00
Description:
FKB station initial setup and configuration - all radiometer data before the end date of 
this time range is suspect. If this data is needed refer to DQ flags and manual assessment 
to determine if data is usable.

Subject:
FKB/SKYRAD/M1 - IRT bias
DataStreams:fkbskyrad60sM1.b1
Description:
On several days (especially in April, September, and December), the sky temperature 
measurement from the IRT exhibited a positive bias from the AERI measurement from about 20:00 
to 07:00. This diurnal variation is highly correlated with the measurement of relative 
humidity so was most-likely due to the contribution of the temperature of water vapor, fog, 
and/or condensation on the lens and/or mirror.
Measurements:fkbskyrad60sM1.b1:
  • IR Brightness Temperature(sky_ir_temp)
  • sky_ir_temp_min
  • sky_ir_temp_max
