Subject:
SGP/SONDE/C1 - Bad RH Data
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The RH values during the first 15 minutes of this sounding oscillate between reasonable 
values and near-zero values.  The oscillation is irregular and seems to be related to 
failure of the RH sensor heating process.  I have informed Vaisala of the problem and provided 
raw data files to them for analysis.
Measurements:sgpsondewnpnC1.a1:
  • Relative humidity inside the instrument enclosure(rh)
  • Surface dew point temperature(dp)
sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Relative humidity inside the instrument enclosure(rh)

SGP/SONDE/C1 - Broken temperature sensor SGP/CF sounding
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The radiosonde temperature sensor apparently broke during launch.  This results in bad 
temperature, dew point, and rh data.
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)

SGP/SONDE/C1 - Bad temperature/RH
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The temperature sensor broke shortly after launch.  All temperature and RH-related data 
are incorrect.
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)
