Subject:
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)

Subject:
TWP/SONDE/C2  - RH sensor failure near surface
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)
