Subject:
SGP/MWR/B1 - thermal instability
DataStreams:sgpmwrlosB1.b1, sgpmwrtipB1.a1
Description:
During periods of high ambient temperature, the instrument may have been thermally 
unstable. The problem was corrected by increasing the RF deck temperature from 50 to 52 C.
Suggestions: 
The data are suspect when the blackbody temperature, tkbb, exceeds 318 K.
Measurements:sgpmwrtipB1.a1:
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
  • Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
  • 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31)
  • 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)

sgpmwrlosB1.b1:
  • Mean 23.8 GHz sky brightness temperature(tbsky23)
  • Mean 31.4 GHz sky brightness temperature(tbsky31)
  • Total water vapor along LOS path(vap)
  • Averaged total liquid water along LOS path(liq)
