Subject:	SGP/QCRAD/E4 - Shortwave fluxes incorrect
DataStreams:	sgpqcrad1longE4.c1, sgpqcrad1longE4.c2, sgpqcrad1longE4.s1, sgpqcrad1longE4.s2
Description:	Shortwave fluxes - direct normal, diffuse, global downwelling, best estimate global, upwelling shortwave - have constant values during this time. The cause of this problem is not known. No instrument DQRs exist for this period.
Suggestions:	null
