| Subject: | TWP/SONDE/C1 - Bad RH sensors |
| DataStreams: | twpsondewnpnC1.00, twpsonderawC1.00, twpsondeC1.00, 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 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. |
| Suggestions: | Some data may be recovered by analysis of the raw data. The RH also might be recovered (though at some degrading of the vertical resolution) by choosing only the highest RH values within each two-minute period of the sounding in this area. |
