SGP/SIRS/C1 - Reprocess: Adjust Direct Normal Irradiance
DataStreams:sgp15swfanalsirs1longC1.c1, sgp1swfanalsirs1longC1.c1, sgpsirsC1.00, sgpsirsC1.01
Description:
Direct normal broadband shortwave irradiance measured by NIP s/n 30722E6 was found to have 
a 0.62%% negative bias when compared in-situ with absolute cavity radiometer 
measurements taken on August 21, 2000.  The estimated measurement uncertainty of the calibration of 
NIP s/n 30722E6 on July 18, 2000 was -2.6% to +4.8%.  

Data from NIP s/n 30722E6 can be adjusted according to the in-situ comparisons to reduce 
the apparent measurement bias.

SGP/SIRS/C1 - SWFANAL Data description error
DataStreams:sgp15swfanalsirs1longC1.c1, sgp1swfanalsirs1longC1.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.
