Subject:	SGP/QCRAD/E25 - missing Best estimate and global values
DataStreams:	sgpqcrad1longE25.c1, sgpqcrad1longE25.c2, sgpqcrad1longE25.s1, sgpqcrad1longE25.s2
Description:	Many best estimate and GSW values are missing during this time period. Some of this data could be filled in using MFRSR measurements.
Measurements:	sgpqcrad1longE25.c1: Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Radiation, shortwave, downwelling total hemispheric irradiance, 1-min avg(down_short_hemisp) sgpqcrad1longE25.c2: Radiation, shortwave, downwelling total hemispheric irradiance, 1-min avg(down_short_hemisp) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) sgpqcrad1longE25.s1: Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) sgpqcrad1longE25.s2: Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp)

Subject:	SGP/QCRAD/E25 - DNI values appear to be incorrect
DataStreams:	sgpqcrad1longE25.c1, sgpqcrad1longE25.c2, sgpqcrad1longE25.s1, sgpqcrad1longE25.s2
Description:	Direct normal irradiance values are strange during this period. No instrument DQR currently exists documenting the problem and its cause is not known.
Measurements:	sgpqcrad1longE25.c1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE25.c2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE25.s1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE25.s2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)

Subject:	SGP/QCRAD/E25 - Noisy LWup Tc/Td
DataStreams:	sgpqcrad1longE25.c1, sgpqcrad1longE25.c2, sgpqcrad1longE25.s1, sgpqcrad1longE25.s2
Description:	Case and dome temperatures for upwelling Longwave fluxes are noisy during this period corresponding to additional noise in the longwave fluxes. No instrument DQRs exist documenting this problem.
Measurements:	sgpqcrad1longE25.c1: LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) LWupTc sgpqcrad1longE25.c2: LWupTc LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) sgpqcrad1longE25.s1: LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) LWupTc sgpqcrad1longE25.s2: LWupTc LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)

DataStreams:	sgpqcrad1longE25.c1, sgpqcrad1longE25.c2, sgpqcrad1longE25.s1, sgpqcrad1longE25.s2
Description:	Upwelling longwave irradiance exceeds physical limits. Data are consistently negative and range from -1000 to -2000 W/sq m due to equipment problem(s). Documented in instrument DQR D021028.1
Measurements:	sgpqcrad1longE25.c1: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) sgpqcrad1longE25.c2: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) sgpqcrad1longE25.s1: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp) sgpqcrad1longE25.s2: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
