Subject:	TWP/SONDE/C2 - Bad RH in lower 8km
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.

Subject:	TWP/SONDE/C2 - Surface Temperature Incorrect
DataStreams:	twpsondewnpnC2.b1
Description:	The first two temperature values in the datafile are incorrect. It appears that the observer mis-typed the surface temperature as -27 instead of +27. The next value was 8 which is also incorrect and was caused by the system interpolating from the incorrect surface value and what the sonde temperature sensor was reading.

Subject:	TWP/SONDE/C2 - Surface RH value incorrect
DataStreams:	twpsondewnpnC2.b1
Description:	The surface RH was reproted as 78%. The value should have been in the low 50's. It appears the observer did not allow the sonde to equilibrate to ambient conditions before taking the reading. This error also caused an incorrect dew point.

Subject:	TWP/SONDE/C1 - Surface RH value incorrect
DataStreams:	twpsondewnpnC1.b1
Description:	The surface RH value of 77% when the value should have been in the low 60's. It appears the observers did not allow the sonde to equilibrate to ambient conditions before collecting the surface data. This error also caused the dew point to be incorrect.
Measurements:	twpsondewnpnC1.b1: Surface dew point temperature(dp) Relative humidity scaled, by total column amount from MWR(rh)

Subject:	TWP/SONDE/C2 - Surface RH Value incorrect
DataStreams:	twpsondewnpnC2.b1
Description:	The surface value entered by the observers for RH (96%) is incorrect. At the ascent time listed in the .ptu file the readings by the Sonde were around 65%. This low RH value is supported by the nearby SMET tower RH reading of 71.8%. This also caused the surface dew point to be incorrect.

Subject:	TWP/SONDE/C2 - Surface RH too high
DataStreams:	twpsondewnpnC2.b1
Description:	The surface Rh was entered as 94%. The ascent time has 72% and this value is supported by RH values from the nearby SMET system. This error also will affect the dew point.
