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 inside the instrument enclosure(rh) Surface dew point temperature(dp) sgpsondewnpnC1.b1: Surface dew point temperature(dp) Dry bulb temperature(tdry) Relative humidity inside the instrument enclosure(rh) sgpqmemwrcolC1.c1: Integrated vapor column from sonde using MWR Instrument Performance Model (IPM)(integ_vap_sonde) sgplssondeC1.c1: Relative humidity inside the instrument enclosure(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.
Measurements:	sgpsondewnpnC1.a1: Dry bulb temperature(tdry) Relative humidity inside the instrument enclosure(rh) Surface dew point temperature(dp) sgpsondewnpnC1.b1: Surface dew point temperature(dp) Dry bulb temperature(tdry) Relative humidity inside the instrument enclosure(rh) sgpqmemwrcolC1.c1: Integrated vapor column from sonde using MWR Instrument Performance Model (IPM)(integ_vap_sonde) sgplssondeC1.c1: Relative humidity inside the instrument enclosure(rh) Dry bulb temperature(tdry)

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.
Measurements:	sgpsondewnpnC1.a1: Dummy altitude for Zeb(alt) Surface dew point temperature(dp) Dry bulb temperature(tdry) Relative humidity inside the instrument enclosure(rh) Ascent Rate(asc) sgpsondewnpnC1.b1: Surface dew point temperature(dp) Relative humidity inside the instrument enclosure(rh) Ascent Rate(asc) Dry bulb temperature(tdry) Dummy altitude for Zeb(alt) sgplssondeC1.c1: Dummy altitude for Zeb(alt) Relative humidity inside the instrument enclosure(rh) Dry bulb temperature(tdry)
