Subject:	SGP/MWR/C1 - calibration checks
DataStreams:	sgpmwrlosC1.b1, sgpmwrtipC1.a1, sgpmwrlosC1.a1
Description:	The MWR calibration was checked by a cryogenic (liquid nitrogen) blackbody target or (in the case of the Sept 2001 time period) by pointing the mirror at an internal blackbody target. The brightness temperatures and vap and liq retrievals are not representative of the sky/atmosphere.
Suggestions:	Do not use data.
Measurements:	sgpmwrlosC1.a1: Mean 31.4 GHz sky brightness temperature(tbsky31) Mean 23.8 GHz sky brightness temperature(tbsky23) Averaged total liquid water along LOS path(liq) Total water vapor along LOS path(vap) more sgpmwrtipC1.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) more sgpmwrlosC1.b1: Averaged total liquid water along LOS path(liq) Total water vapor along LOS path(vap) Mean 23.8 GHz sky brightness temperature(tbsky23) Mean 31.4 GHz sky brightness temperature(tbsky31) more
