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)
