Subject:	SGP/SONDE/C1 - Bad Temperature Sensor
DataStreams:	sgplssondeC1.c1, sgpqmemwrcolC1.c1, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:	It appears that the temperature sensor broke upon launch and therefore the reported temperature is approximately 40 degC too low.
Measurements:	sgpsondewnpnC1.a1: Dry-Bulb Temperature(tdry) Relative humidity scaled, by total column amount from MWR(rh) Surface dew point temperature(dp) sgpsondewnpnC1.b1: Surface dew point temperature(dp) Dry-Bulb Temperature(tdry) Relative humidity scaled, by total column amount from MWR(rh) sgpqmemwrcolC1.c1: Integrated vapor column from sonde using MWR Instrument Performance Model (IPM)(integ_vap_sonde) sgplssondeC1.c1: Relative humidity scaled, by total column amount from MWR(rh) Dry-Bulb Temperature(tdry)

Subject:	SGP/SONDE/C1 - Bad Temperature Sensor
DataStreams:	sgplssondeC1.c1, sgpqmemwrcolC1.c1, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:	It appears that the temperature sensor broke shortly after launch. Temperatures are offset by approxmiately (but not constantly) 40 degC.

Subject:	Bad temperature sensor
DataStreams:	sgplssondeC1.c1, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:	It appears that the temperture sensor broke a few seconds into flight. This results in an unreasonably low temperature for the rest of the flight. For some reason, the rh values also go missing shortly after launch. Only the wind and pressure data are reliable.
