Subject: TWP/SONDE/C1 - Bad RH at beginning of sounding
Affected Datastreams: 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 between low (~2 %RH) and not so low (~80 %RH) and the oscillation seems to stop when the temperature is below ~40 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating.

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.

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.

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 (~5 %RH) and not so low (~70 %RH) and the oscillation seems to stop when the temperature is below ~40 degC.

Subject: TWP/Sonde/C1 - Bad RH Values
Affected Datastreams: twpsondewnpnC1.a1
Description The RH values from the surface to approximately 11.5 km oscillate between reasonable values and zero. This is apparently caused by a failure in the RH sensor heating process. Although the oscillation stops when the heating stops (at temperatures below ~ -45degC) I think the values must be viewed as suspect.

Subject: TWP/SONDE/C1 - Bad RH in short interval aloft
Affected Datastreams: twpsondewnpnC1.b1
Description It appears that the RH sensor heating circuit on this sonde failed about 31 minutes into the flight. The RH values look reasonable from the surface to approximately 8.25 km at which point they begin to oscillate between 0 and 40%. This behavior stops when the sonde reaches approximately 11.0km when the air temperature drops below -40 degC. The oscillation stops at that point, though the RH remains higher than might be expected even under supersaturated conditions.

Description It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 5km and 10km). The RH oscillates rapidly between low (~5 %RH) and not so low (~50 %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.

Affected Datastreams: twpsondewnpnC1.b1
Description A GPS problem associated with Vaisala BBSS ground station software issues caused the ground stations to enter into an error state when using GPS wind finding. In some instances, the flight was aborted due to the error state and not data was collected. A workaround was developed to allow sondes to be launched without collecting wind data.
