titlePlease take into account if you use multiple data stores:

For access to different data stores (cds.ecmwf.int, ecds.ecmwf.int, etc.)the user must have separate .cdsapirc files with the correct URL for given data store. Alternatively, the URL and user token can be part of the Python client definition as per Examples in User guide for migration of S2S and TIGGE to ECDS.

Find all information how to access a dataset in ECDS and the available tools and tutorials in the ECDS home page

...

  1. Install CDS-API personal access token and client.
  2. Search for data and generate CDS-API request by using dedicated ECDS forms (TIGGE, S2S real-time forecasts, and S2S reforecast) or MARS data catalogue (TIGGE and S2S).
    • Please be aware that there are different versions of CDS-API syntaxes generated by ECDS form and by MARS catalogue. Full details and examples are available inUser guide for migration of S2S and TIGGE to ECDS.
      Warning
