Subject:
SGP/BRS/C1 - SWFANAL Data description error
DataStreams:sgp1swfanalbrs1longC1.c1, sgp15swfanalbrs1longC1.c1
Description:
The long name attribute for the cloud effect fields incorrectly
defines the cloud effect to be the difference between the 
clearskyfit and measured values:
   
"Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ;
   
The cloud effects are correctly calculated by subtracting the
irradiance calculated in the clear sky fit from the measured 
irradiance.
   
"Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ;
   
NOTE: this is just a documentation error.  The data are correctly
calculated.
Measurements:sgp15swfanalbrs1longC1.c1:
