SGP/SONDE/C1 - Bad temp (other?) data in 12/3/01:2328 sounding
DataStreams:sgpsondeC1.00, sgpsondewnpnC1.00, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
It looks as though the temperature sensor was damaged on launch.  The
recorded temp goes from 16.4 at the surface to -42.6 at 2 seconds into the
flight.  The temperature never exceeds -42 though the RH and pressure look
reasonable, but probably should be considered questionable.
Measurements:sgpsondewnpnC1.00:
  • Raw data stream - documentation not supported(Raw data stream - documentation not supported)

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)

SGP/SONDE/C1 - Bad temperature in CF sounding 12/22/01:0527
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The temperature data in this sounding look bad after the first value.  The
temperature series is 11.4, 2.6, -14.3, -32.4 in the first 6 seconds of
flight.  I don't know why this occurred, but it obviously is incorrect.
The pressure and RH data look reasonable.
Measurements:sgpsondewnpnC1.a1:
  • Dry-Bulb Temperature(tdry)
  • Surface dew point temperature(dp)

sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)

Subject:
SGP/SONDE/C1 - Bad temperature data CF sounding 12/28/01:2326
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The temperature data in this sounding are bad from approximately 16 seconds
into the flight.  The temperature series is 9.9, 10.8, 11.3, 1.5, 11.6, 11.6,
11.6, -32.2 and remains below -30 degC.  I don't know why this occurred, but
it clearly is incorrect.  The pressure data looks OK as does the RH, though
the RH data are missing (probably sensor failure) above roughly 3.5 km.
Measurements:sgpsondewnpnC1.a1:
  • Dry-Bulb Temperature(tdry)
  • Surface dew point temperature(dp)

sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry-Bulb Temperature(tdry)
