Subject:
TWP/SONDE/C1 - Bad RH sensor
DataStreams:twpsondewnpnC1.b1, twpsondewnpnC1.a1
Description:
It appears that the RH sensor heating circuit failed during this portion of the sounding 
(approximately between the surface and 11km).  The RH oscillates rapidly between low (~0 
%RH) and high (~80 %RH) and the oscillation seems to stop when the temperature is below 
~40 degC.  According to Vaisala these are symptoms of failure in the ASIC (application 
specific integrated circuit) that controls the heating.
Suggestions: 
null
Measurements:twpsondewnpnC1.b1:
  • Dewpoint Temperature(dp)
  • Relative Humidity (hybrid-b grid)(rh)
