| Subject: | TWP/SONDE/C2 - Bad RH sensor |
| 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 -50 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |
| Suggestions: | null |
