Please note :
- sd, tp, t2m, u10 and v10 , v10, i10fg and z_500 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.
