| 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.
