Grid description | We used a nb_lines*nb_columns = 385*370 points over Africa with a 0.2° step. Only grid cells on land were computed.
NB: the formula to convert (lat, lon) into grid cell is:

Volume content | Each HDF5 dataset comprises 420768 maps. 420768 is the number of 15 min periods from 2005-01-01 to 2016-12-31: 96 periods per day * 365 days * 12 years + 96 * 3 days (for 2008, 2012 and 2016 leap years). Each value in HDF5 files is stored as an unsigned byte:
If you extract ghi.h5 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 |
