DataStreams:	sgpqcrad1longE15.c1, sgpqcrad1longE15.c2, sgpqcrad1longE15.s1, sgpqcrad1longE15.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. There were no instrument DQRs on this problem at the time this report was submitted.

Subject:	SGP/QCRAD/E15 - Temp and RH measurements incorrect
DataStreams:	sgpqcrad1longE15.c1, sgpqcrad1longE15.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. Most periods with missing data described in instrument DQRs: D980521.1, D980616.1

Subject:	SGP/QCRAD/E15 - Upwelling shortwave flux appears bad
DataStreams:	sgpqcrad1longE15.c1, sgpqcrad1longE15.c2, sgpqcrad1longE15.s1, sgpqcrad1longE15.s2
Description:	Upwelling shortwave flux appears to be bad during these periods. Flux shows extended periods with zero values. The reason for this is not known. No instrument DQRs available describing this problem.
Measurements:	sgpqcrad1longE15.c1: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE15.c2: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE15.s1: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE15.s2: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)

Subject:	SGP/QCRAD/E15 - Direct normal irradiance intermittently low
DataStreams:	sgpqcrad1longE15.c1, sgpqcrad1longE15.c2, sgpqcrad1longE15.s1, sgpqcrad1longE15.s2
Description:	Direct normal irradiance measurements appear to be intermittently too low and possibly incorrect during this time period. The cause is not known. No instrument DQRs currently exist describing the problem.
Measurements:	sgpqcrad1longE15.c1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE15.c2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE15.s1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) sgpqcrad1longE15.s2: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
