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 02 February 2023 all months up to 202211 are the final version of ERA5. The month of 202212-202301 was also downloaded, but is from the temporary version of ERA5 and will be replaced in the near future.
Please note :
- sd, tp and t2m 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.
