| Subject: | SGP/QCRAD/E1 - Tracker malfunction |
| DataStreams: | sgpqcrad1longE1.s2, sgpqcrad1longE1.c2 |
| Description: | The solar tracker was inoperative during these time periods indicating that the shortwave direct normal, the shortwave diffuse, and possibly the downwelling longwave irradiance are inaccurate. This also impacts the best estimate value because the sum of direct and diffuse cannot be used, and some tests can't be applied to the data. Some problems documented in instrument DQRs: D090520.1 & D090121.1 |
