Subject:	SGP/QCRAD/E4 - UPS failure
DataStreams:	sgpqcrad1longE4.c1, sgpqcrad1longE4.c2, sgpqcrad1longE4.s1, sgpqcrad1longE4.s2
Description:	On Jan 13th approximately 1400GMT the UPS failed at E4. This affected both the global and tracker mounted instruments. The affected measurements are down_short_hemisp(PSP), down_short_diffuse(8-48) and direct_normal(NIP) measurements. The PSP down_short_hemisp measurement doesn't rely on the tracker but is power ventilated and is adversely affected by daytime solar heating when the ventilator power fails. Documented in instrument DQR D080212.3

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.

Subject:	SGP/QCRAD/E4 - Missing surface met data
DataStreams:	sgpqcrad1longE4.c1, sgpqcrad1longE4.c2
Description:	Surface meteorological data were missing during these time periods. Met data is used in a variety of quality control checks described below. Air temperature data is needed for tests on LW up and LW down pyrgeometer case and dome temperatures, and tests on the irradiances from upwelling LW/SW and downwelling LW. The Rayleigh limit diffuse radiation test is based on surface pressure. Documented in instrument DQR D991109.3
