Downward Longwave Irradiance (DLI) estimates reaching the Earth's surface, derived from the 0.6µm visible channel of the SEVIRI instrument on the Meteosat geostationary satellite. EUMETSAT produces this data by remapping hourly values onto a 0.05-degree regular grid and integrating them into daily values expressed in watts per square meter (W/m²). The algorithm uses a bulk parameterization that incorporates Numerical Weather Prediction model outputs and satellite-derived cloud information.
Daily values represent the integration of all hourly values within a UT day. Users must understand the algorithm's dependence on NWP model data. Access may be governed by EUMETSAT's data policy.
