[!IMPORTANT] The old Climate Data Store (CDS) will be shut down on 3 September 2024. All era5cli versions up to v1.4.2 will no longer work.

For more information see: https://forum.ecmwf.int/t/the-new-climate-data-store-beta-cds-beta-is-now-live/3315

To continue using era5cli, you will need to re-register at ECMWF and get a new API key, and transition to the era5cli v2 beta. This can be installed with: pip install era5cli==2.0.0b2

[!WARNING] netCDF files from the new Climate Data Store Beta are not formatted the same as the old CDS. Some variables might be missing. See the open issue here, as well as the ECMWF discussion forum.

• List and retrieve information on available variables and pressure levels
• Select multiple variables for several months and years
• Split outputs by years (and optionally months), producing a separate files instead of merging them in one file
