Subject: | SGP/SIRS/E7 - Instrument noise |
DataStreams: | sgpsirsE7.b1, sgpsirs20sE7.a0 |
Description: | Beginning around 10/31, the E7 UIR experienced an increasingly noisy signal. The thermopile signal was noisy, but case and dome thermistors are well behaved. Maintenance reseated the UIR cable connections on 12/12/2006 which effectively eliminated the UIR noise. The thermopile data from the upwelling pyrgeometer is noisy with resulting irradiance variations of up to 5 W/m2, but doesn't appear to have a bias. |
Suggestions: | Use data during this time range at users discretion. |
