Surface Radiation Retrieval

Published: 13 August 2012

In this first part of the presentation on short wave solar radiation fluxes, Rebekka Posselt explains the algorithms used for calculation of the products from MeteoSat first generation satellite data. Two algorithms are presented; MagicSol for the retrieval of historical radiation data and a lookup table method for the operational radiation products. In the second part of the presentation, Aku Riihelä explains the (Surface ALbedo) SAL retrieval algorithm. He also gives an introduction on the various corrections applied to the data to take into account for topography, surface characteristics and sun elevation.
