Subject:
TWP/SONDE/C1 - Bad RH sensors
DataStreams:twpsondewnpnC1.00, twpsonderawC1.00, twpsondeC1.00, twpsondewnpnC1.b1
Description:
It appears that the RH sensor heating circuit failed during this portion of the sounding 
(approximately between 0km and 12km).  The RH oscillates rapidly in a 20% range and the 
oscillation seems to stop when the temperature is below ~45 degC.  These are symptoms of 
failure in the ASIC (application specific integrated circuit) that controls the heating.
Suggestions: 
null
