Subject: | SGP/BRS/C1 - low downwelling shortwave readings |
DataStreams: | sgpbrsC1.a2, sgpbrsC1.00, sgpbrs60sC1.a1, sgpbrs20sC1.a0 |
Description: | Downwelling shortwave (DS) values frequently drop below -10 W/m^2 at night, and are consistently 20-40 W/m^2 less than the calculated downwelling shortwave during the day in clear-sky conditions. Corrective maintenance on 12/1/2004 corrected this offset. It is not clear which CM action corrected the problem since the DS instrument cable was grounded to a new location and the DS ventilator fan was found in poor condition and was replaced. Either of these issues could have led to the problem observed in this instrument. |
