Subject:	SGP/QCRAD/E4 - Tracker inoperative
DataStreams:	sgpqcrad1longE4.c2
Description:	Tracker failed on 04/02 until reset by Ops on 5/13. This adversely affected down_short_diffuse_hemisp and short_direct_normal data. Data are not recoverable. documented in instrument DQR D090424.2
Measurements:	sgpqcrad1longE4.c2: Shortwave Direct Normal Irradiance(short_direct_normal) Irradiance, shortwave, downwelling, diffuse, hemispheric, pyranometer(down_short_diffuse_hemisp) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)

Subject:	SGP/QCRAD/E19 - Met data bad or missing
DataStreams:	sgpqcrad1longE19.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. There were no instrument DQRs on this problem at the time this report was submitted.

Subject:	SGP/QCRAD/E7 - Tc/Td bad/missing/noisy
DataStreams:	sgpqcrad1longE7.c2
Description:	Case and dome temperatures for longwave fluxes are missing, bad, or noisy during this period corresponding to additional noise in the longwave fluxes. Some checks to the longwave fluxes cannot be performed when Tc/Td are missing. No instrument DQRs exist documenting this problem.
Measurements:	sgpqcrad1longE7.c2: Downwelling longwave hemispheric irradiance, pyrgeometer(down_long_hemisp) Upwelling longwave hemispheric irradiance, pyrgeometer(up_long_hemisp) LWupTc LWupTd LWdnTc LWdnTd
