We have set up the existing method of Cano (1982) to assess the global solar radiation using images acquired by the Meteosat satellite. The method is validated against approximately 1800 ground measurements taken during 11 months in 1983, 11 months in 1984 and 7 months in 1985. The major points of this method are 1) the construction of a map of planetary albedo in clear skies, 2) the estimation of a cloud index, n, denoting the percentage of cloud coverage within a pixel relatively to the albedo reference map, 3) the assessment of the relationship between the hourly atmospheric transmittance (K), defined as the ratio between the gloabl radiation and the radiation at the top of the atmosphere (G0h), and the cloud index n. The relationship ha...
