Fields are in monthly files with one variable per file. Files are compressed with a deflate level of 6 and chunked to the grid dimension. Please note that as 11 April 2024 all months up to 202312 were downloaded and are the final version of ERA5.
Please note :
- msl, sd, tp, t2m, u10, v10, i10fg, z_500, sst and siconc are available from 194001
- even if the output of sst and siconc is available hourly from CDS API, it only change one time a day, so it was downloaded only at 12Z.
- Due to interpolation from the gaussian grid to the global latlon grid by ECMWF and also due a precision loss when packing the fields into an integer, it can happen to have very small negative precipitation values.
