Subject:
SGP/QCRAD/E7 - Problems with downwelling shortwave flux
DataStreams:sgpqcrad1longE7.c2, sgpqcrad1longE7.s2, sgpqcrad1longE7.c1, sgpqcrad1longE7.s1
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.
Suggestions: 
If "source_BestEstimate_down_short_hemisp" is -1, use sumSW instead of Best Estimate SW.
