| Subject: | SGP/SIRS/E18 - SWFANAL Data description error |

| 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. |
