Subject: | SGP/SONDE/C1 - Bad RH Data |
DataStreams: | sgpsondewnpnC1.b1, sgpsondewnpnC1.a1
|
Description: | The RH values during the first 15 minutes of this sounding oscillate between reasonable
values and near-zero values. The oscillation is irregular and seems to be related to
failure of the RH sensor heating process. I have informed Vaisala of the problem and provided
raw data files to them for analysis. |
Suggestions: | Near zero RH values are incorrect and the other RH values obtained during the first
15 minutes of the sounding are suspect. Because the problem is related to the heating
circuit, we cannot recover the RH data when both RH sensors are heated. |
