SGP/QCRAD/E18 - Global SW data incorrect
DataStreams:sgpqcrad1longE18.c1, sgpqcrad1longE18.s2, sgpqcrad1longE18.s1, sgpqcrad1longE18.c2
Description:
Global shortwave and best estimate SW data appear incorrect during this time. The cause is 
not known.  No instrument DQRs are currently available describing the problem.
Suggestions: 
Use alternate measurements for global shortwave during this time - either the sum of 

direct and diffuse irradiance or the MFRSR data
