Subject: | TWP/SONDE/C2 - Failure of RH sensor |
DataStreams: | twpsondewnpnC2.b1, twpsondewnpnC2.a1
|
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 ~35 degC. According to Vaisala 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. |
