Subject:
TWP/SONDE/C2 - RH sensor bad
DataStreams:twpsondewnpnC2.b1
Description:
It appears that the RH sensor heating circuits failed during these
soundings.  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.
Suggestions: 
null
Measurements:twpsondewnpnC2.b1:
  • Relative Humidity (hybrid-b grid)(rh)
  • Dewpoint Temperature(dp)
