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)

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 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)

  • Integrated vapor column from sonde using MWR Instrument Performance Model (IPM)(integ_vap_sonde)

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.

  • Surface dew point temperature(dp)

  • Relative humidity scaled, by total column amount from MWR(rh)
  • Ascent Rate(asc)
