| Subject: | TWP/SONDE/C1 - Bad RH in short interval aloft |
| 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. |
| Suggestions: | I suggest discarding all RH data collected between 8.25-11.0 km. |
