Subject:
TWP/SONDE/C2 - Failure of RH sensor
DataStreams:twpsondewnpnC2.b1
Description:
The RH sensor ASIC that controls the sensor heating failed.  As a result the RH at the 
beginning of the sounding oscillates between near-zero and ambient values.  The RH heating 
cycle stops when the ambient temperature reaches below -30 degC; above this level RH 
values should be valid.
Suggestions: 
Accept reduced vertical resolution and use maximum values in approximately 900 meter 

layers.
