Subject: SGP/SIRS/E13 - SWFANAL Data description error
Affected Datastreams: sgp15swfanalsirs1longE13.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
  • difswfluxdn_cloudeffect (Difference: difswfluxdn_measured - difswfluxdn_clearskyfit (diffcg))
  • sswfluxdn_cloudeffect (Difference: sswfluxdn_measured - sswfluxdn_clearskyfit (sswfcg))
  • gswfluxdn_cloudeffect (Difference: gswfluxdn_measured - gswfluxdn_clearskyfit (gswfcg))
