| Subject: | SGP/QCRAD/E21 - Tracker out of alignment |
| DataStreams: | sgpqcrad1longE21.s2, sgpqcrad1longE21.s1, sgpqcrad1longE21.c1, sgpqcrad1longE21.c2 |
| Description: | Tracker appears to be out of alignment or inoperative during these times. The short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data appear to be bad and not recoverable. Some of these dates are documented in instrument DQRs: D030529.3, D030612.1, D030722.2, D040229.2, D080602.2, D080722.1 |
| Suggestions: | Don't use SW direct or diffuse data during these time periods. If "source_BestEstimate_down_short_hemisp" is 0, don't use Best Estimate GSW data. Note that fewer quality checks can be applied accurately to the BestEstimate data. |
