Hourly Downward Longwave Irradiance - MSG
Listed in NASA Earthdata CMR
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.
Description
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).
