| 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 (~5 %RH) and not so low (~70 %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. |
