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 04 November 2023 all months up to 202211 202308 were downloaded and 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.
