Subject:	SGP/QCRAD/E16 - Tracker alignment issue
DataStreams:	sgpqcrad1longE16.c1, sgpqcrad1longE16.c2, sgpqcrad1longE16.s1, sgpqcrad1longE16.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 appear to be bad and not recoverable. There were no instrument DQRs on this problem at the time this report was submitted.

Subject:	SGP/QCRAD/E16 - Met data not available
DataStreams:	sgpqcrad1longE16.c1, sgpqcrad1longE16.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/E16 - Upwelling shortwave flux bad
DataStreams:	sgpqcrad1longE16.c1, sgpqcrad1longE16.c2, sgpqcrad1longE16.s1, sgpqcrad1longE16.s2
Description:	Upwelling shortwave flux appears to be bad during this time. The cause is not known. No instrument DQR exists explaining the problem.
Measurements:	sgpqcrad1longE16.s2: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE16.s1: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE16.c1: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp) sgpqcrad1longE16.c2: Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)

Subject:	SGP/QCRAD/E16 - Tc/Td bad or noisy
DataStreams:	sgpqcrad1longE16.c1, sgpqcrad1longE16.c2, sgpqcrad1longE16.s1, sgpqcrad1longE16.s2
Description:	Case and dome temperatures for Longwave fluxes are sporadically bad or noisy during these periods corresponding to additional noise in the longwave fluxes. Some checks can't be applied to the LW fluxes. No instrument DQRs exist documenting this problem.
