Grid description | We used a grid of nb_columns*nb_lines = 3600*1800 points over the whole world with a 0.1° step. Grid:
NB: the formula to convert (lat, lon) into grid cell is:
NB: Only grid cells on land or close to sea shore were computed. Only grid cells in Meteosat and Himawari fields of view were computed:

Volume content | Each NetCDF dataset comprises up to 2976 maps, which correspond to the number of 15 min periods in 1 month. Each value in NetCDF files contains 15 min irradiation in Wh/m². The value NaN denotes a grid cell over the sea or out of MSG field of view (not computed) or a computation error. WARNING: Data are compressed in NetCDF files. In version 4.5, end users had to convert 254 and 255 values to NaN, and to multiply the other values by 1.2. In version 4.6, this is done automatically by NetCDF library.
