Subject: | SGP/QCRAD/E4 - Tracker failure |
DataStreams: | sgpqcrad1longE4.c1, sgpqcrad1longE4.c2, sgpqcrad1longE4.s1, sgpqcrad1longE4.s2 |
Description: | On 4/2, the station experienced a power drop after which the tracker was not operational until it was reset on 5/1. The short_direct_normal (NIP instrument) and down_short_diffuse_hemispheric (8-48 instrument) data were bad during this time. The down_long_hemispheric (PIR) and down_short_hemispheric were unaffected by this failure. Upwelling instruments were also unaffected. Three component DQ checks were not valid during this time. Documented in instrument DQR D080422.2 |
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. |
