TWP/SONDE/C2 - Broken temperature sensors
DataStreams:twpsondewnpnC2.b1
Description:
The temperature sensors on these radiosondes broke after launch.  All
temperature-related data are incorrect.
Measurements:twpsondewnpnC2.b1:
  • Relative humidity inside the instrument enclosure(rh)
  • Dry bulb temperature(tdry)
  • Surface dew point temperature(dp)

TWP/SONDE/C2  - RH sensor failure below 9km
DataStreams:twpsondewnpnC2.b1
Description:
It appears that the RH sensor heating circuit failed during this sounding.  The RH 
oscillates rapidly between low (~0 %RH) and not so low (ambient %RH) and the oscillation seems 
to stop when the temperature is below ~35 degC.  According to Vaisala these are symptoms 
of failure in the ASIC (application specific integrated circuit) that controls the heating.
Measurements:twpsondewnpnC2.b1:
  • Relative humidity inside the instrument enclosure(rh)
  • Surface dew point temperature(dp)

TWP/SONDE/C2 - Bad RH values aloft
DataStreams:twpsondewnpnC2.b1
Description:
It appears that the RH sensor heating circuit on these sondes failed after launch but 
resume proper operation when the ambient temperature dropped below ~40 degC.
Measurements:twpsondewnpnC2.b1:
  • Relative humidity inside the instrument enclosure(rh)
  • Surface dew point temperature(dp)

TWP/SONDE/C2 - Bad RH sensor
DataStreams:twpsondewnpnC2.b1
Description:
It appears that the RH sensor heating circuit failed during this sounding.  The RH 
oscillates rapidly between low (~0 %RH) and not so low (ambient %RH) and the oscillation seems 
to stop when the temperature is below -50 degC.  According to Vaisala these are symptoms 
of failure in the ASIC (application specific integrated circuit) that controls the heating.
