DataStreams:	sgpqcrad1longE7.c1, sgpqcrad1longE7.c2, sgpqcrad1longE7.s1, sgpqcrad1longE7.s2

Subject:	SGP/QCRAD/E7 - Questionable shortwave radiometer data
DataStreams:	sgpqcrad1longE7.c1, sgpqcrad1longE7.c2, sgpqcrad1longE7.s1, sgpqcrad1longE7.s2
Description:	Diffuse, direct normal flux appear questionable, possibly also total downwelling shortwave flux. The source of this problem is not known. No instrument DQRs exist for this problem.

Subject:	SGP/QCRAD/E7 - Problems with downwelling shortwave flux
DataStreams:	sgpqcrad1longE7.c1, sgpqcrad1longE7.c2, sgpqcrad1longE7.s1, sgpqcrad1longE7.s2
Description:	The downwelling shortwave values were dropping out. These got transferred to the best estimate total flux data. PSP data (down_short_hemisp) is not recoverable but can be calculated using: global = direct*cos(zenith angle) + diffuse See the SIRS instrument handbook for details of this component sum method.

Subject:	SGP/QCRAD/E7 - Shortwave fluxes appear to be too low
DataStreams:	sgpqcrad1longE7.c1, sgpqcrad1longE7.c2, sgpqcrad1longE7.s1, sgpqcrad1longE7.s2
Description:	All shortwave fluxes--best estimate global, global downwelling, diffuse, direct normal, and upwelling shortwave--are too low during this period. The cause of this problem is not known. There are no instrument DQRs on this problem.

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.
