Hourly Downward Longwave Irradiance - MSG

Abstract:
Estimation of the Downward Longwave Irradiance reaching the Earth surface, derived from the geostationary satellite Meteosat, derived at present from the 0.6µm visible channel of SEVIRI, produced by remapping over a 0.05° regular grid and expressed in W/m2. Algorithm is a bulk parameterization that uses NWP model outputs to calculate a clear sky Downward Longwave Irradiance (DLI), corrected according to satellite derived cloud information. An essential point is the calculation of products interpolated at rounded UT hours. A radiative flux calculated on a satellite image is not homogeneous in time (the pixel time varies from north to south, of about 12 minutes for Meteosat data).
