Resum

Diversos productes de precipitació utilitzen radiances i reflectàncies obtingudes a partir del sensor SEVIRI (Spinning Enhanced Visible and Infrared Imager) per estimar la precipitació de caràcter convectiu. És sabut que l'ús directe d'aquests valors en algorismes de precipitació sobreestima l'àrea i subestima la intensitat de precipitació.

Resum

S'ha realitzat la comparació dels valors mitjos mensuals d'irradiància global diària mesurats en 40 estacions de la Xarxa Radiomètrica Nacional en banda ampla de l'Agència Estatal de Meteorologia amb els valors mensuals de Surface Incoming Shortwave radiation (SIS) del Climate Monitoring-Satellite Application Facility per a l'any 2006. Es calcula a partir de les dades de l'instrument Spinning Enhanced Visible and Infrared Imager del satèl·lit Meteosat de Segona Generació i de l'Advanced Very High Resolution Radiometer dels satèl·lits polars de la NOAA.
