Subject:	TWP/SONDE/C1 - Broken temperature sensor
DataStreams:	twpsondewnpnC1.b1
Description:	The temperature sensor on these radiosondes broke after launch All the temperature-related data are incorrect.
Measurements:	twpsondewnpnC1.b1: Surface dew point temperature(dp) Relative humidity scaled, by total column amount from MWR(rh) Dry-Bulb Temperature(tdry)

Subject:	SGP/SONDE/C1 - Incorrect surface temperature
DataStreams:	sgpsondewnpnC1.b1
Description:	The operator entered a the surface temperature incorrectly on this sounding. The sonde data file shows the temperature as 33.5 degC but the operations log shows it as 3.5 degC. The first temperature recorded by the sonde after launch is 3.7 degC, consistent with the typical early morning inversion.

Subject:	TWP/SONDE/C1 - Bad RH at beginning of sounding
DataStreams:	twpsondewnpnC1.b1
Description:	It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~1 %RH) and high (~80 %RH). According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating.
