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:
  • Sky Infra-Red Temperature(sky_ir_temp)
  • Sky Infra Red Temperature Minima(sky_ir_temp_min)
  • Sky Infra Red Temperature Maxima(sky_ir_temp_max)
