Grid description | We used a grid of nb_columns*nb_lines = 371*386 points over Africa with a 0.2° step. Only grid cells on land were computed. Download the list of the 2371*386 grid points in CSV format. Grid:
NB: the formula to convert (lat, lon) into grid cell is:

Volume content | Each HDF5 dataset comprises 35040 maps, which correspond to the number of 15 min periods in 1 year (35136 maps for leap years). Each value in HDF5 files is stored as an unsigned byte:
If you extract hdf5 data as a time series for one location, you will get almost the same data as CAMS Radiation web interface. The small difference is due to the data compression as 1 byte per value in JADE. | ![]() Click on the image to magnify: GHI on 2005-04-01 from 11h45 to 12h00 UT |
