DataStreams:	sgpqcrad1longE9.c1, sgpqcrad1longE9.c2, sgpqcrad1longE9.s1, sgpqcrad1longE9.s2
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 apear to be bad and not recoverable. Documented in instrument DQRs: D060718.2 & D070312.1

Subject:	SGP/QCRAD/E9 - Missing surface met data
DataStreams:	sgpqcrad1longE9.c1, sgpqcrad1longE9.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/E9 - direct normal appears bad
DataStreams:	sgpqcrad1longE9.c1, sgpqcrad1longE9.c2, sgpqcrad1longE9.s1, sgpqcrad1longE9.s2
Description:	Direct normal irradiance measurements appear to be incorrect. The cause of the problem is not known. No instrument DQR is available describing the problem at this time.
Measurements:	sgpqcrad1longE9.c2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE9.c1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE9.s2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE9.s1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)

Subject:	SGP/QCRAD/E9 - Noisy Longwave Tc/Td
DataStreams:	sgpqcrad1longE9.c1, sgpqcrad1longE9.c2, sgpqcrad1longE9.s1, sgpqcrad1longE9.s2
Description:	Case and dome temperatures for Longwave fluxes are noisy during this period corresponding to additional noise in the longwave fluxes. No instrument DQRs exist documenting this problem.
Measurements:	sgpqcrad1longE9.c2: LWupTd LWupTc Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) LWdnTc LWdnTd sgpqcrad1longE9.c1: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) LWupTd LWupTc LWdnTc LWdnTd Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) sgpqcrad1longE9.s2: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) LWdnTd LWdnTc LWupTc Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) LWupTd sgpqcrad1longE9.s1: LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) LWdnTc LWdnTd LWupTc
