Subject:
SGP/MWR/E14 - Bias in 23.8-GHz measurements
DataStreams:sgpmwrlosE14.b1, sgpmwrtipE14.a1
Description:
Since the instrument was returned after a power supply failure the 23.8-GHz channel is 
constantly 3 K higher than the other co-located radiometer (C1). Since the instrument was 
just returned after extensive refurbishing at the manufacturer the cause of the bias is not 
clear.
Measurements:sgpmwrtipE14.a1:
  • 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
sgpmwrlosE14.b1:
  • Sky brightness temperature at 23.8 GHz(tbsky23)
  • MWR column precipitable water vapor(vap)
