Subject:
TWP/QCRAD/C2 - Direct normal reading too low
DataStreams:twpqcrad1longC2.c2, twpqcrad1longC2.s2, twpqcrad1longC2.s1, twpqcrad1longC2.c1
Description:
Direct normal irradiance data is bad. Described in instrument DQR D080313.2.
Suggestions: 
Do not use direct normal irradiance data during these time periods. If 

"source_BestEstimate_down_short_hemisp" is 0, don't use Best Estimate GSW data. Note that fewer 
quality checks can be applied accurately to the BestEstimate data.
