  • Create a new EWDS-Beta account and accept EWDS-Beta Terms & Conditions at https://ewds-beta.climate.copernicus.eu/
  • Accept the licences of the product you are interested in (go to the Download form of the product of interest).
  • For API access:
    • Update API credentials and end point (eg. in your .cdsapirc file) as shown, after logging on here (Note that new .cdsapirc file should only contain a URL and a key field - there is NO UID field anymore).
    • Upgrade your CDS API (i.e pip install --upgrade cdsapi). Please make sure you are using a supported version of Python i.e. 3.8 and above. 
    • New API is designed to be backward compatible which means that once your .cdsapirc is updated and your CDS API package upgraded, your API script may run successfully immediately, downloading data from CDS-Beta. There are a few datasets however for which API syntax may have changed - please check the warning on the catalogue page of the affected datasets (e.g. E-OBS). 
    • Run a small API test request.

A new state-of-the-art infrastructure, referred to as the Common Data Store (CDS) Engine, has been developed by ECMWF to host the Climate and Atmospheric Data Stores.  All layers of the infrastructure are being modernised: the front-end web interface, the back-end software engine, and the underlying cloud infrastructure hosting the service and core data repositories.

  • For the time being, DOIs of datasets in CDS-Beta will point to the same datasets in the current CDS until the current CDS is shut down in September 2024.
  • The current CDS and ADS will be completely shut down in September 2024. Please migrate to using the new CDS/ADS/EWDS by September 3rd16th, 2024. Should users still have API scripts pointing to the retired CDS and ADS systems, these will systematically break and no support will be provided.
