Subject: | TWP/SONDE/C1 - Bad RH sensor |
DataStreams: | twpsondewnpnC1.b1, twpsondewnpnC1.a1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between the surface and 11km). The RH oscillates rapidly between low (~0 %RH) and high (~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. |
