The ECDS is powered by CDS technology (access via CDS-API, discovery forms etc). It shares the same authentication system, so that users can access any dataset across all data stores (CDS, ADS, EWDS, ECDS) with with their ECMWF User account . Currently, each data store uses its own key and consequently, users accessing more than one platform need to use specific key for each platformand the same API key which is shared between all data stores.
Find all information how to access a dataset in ECDS and the avaiable available tools and tutorials in the ECDS home page
How to get data
Get data interactively (manually over the web) Users can download data interactively from the ECDS website using the Download Data tab form for given dataset... |
Get data programmatically (API service) ...or programmatically using the API service. API guidelines including Troubleshooting are provided! |
ECDS datasets
TIGGE and S2S
The data access to TIGGE and S2S is now being migrated from WEB-API to CDS-API (in ECDS). For more information about the timelines, please consult the dedicated page Decommissioning of ECMWF Public Datasets service. |
The comprehensive overview of the older and new ways how to access TIGGE or S2S data and the related tools is |
available in User guide for migration of S2S and TIGGE to ECDS. Users with experience getting the data via older WEB-API can found there information how to update their workflows. |
TIGGE and S2S have been the first datasets moved to ECDS. Follow the links below to the dedicated main web spaces for given dataset:
To discover avaiable available data and get them from ECDS, multiple options exist:
...
Discover and download sample data by using dedicated ECDS forms (TIGGE, S2S, and S2S-reforecast) or MARS data catalogue (see table below)
...
(TIGGE and S2S). Both systems show identical data, only the interface is different

Get data programmatically
- Install CDS-API personal access token and client.
- Search for data and generate CDS-API request by using dedicated ECDS forms (TIGGE, S2S, 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 title Please take into account some considerations about the content: - Different ECMWF Public Datasets include different "parameters" , "times", and "steps"
- In each ECMWF Public Dataset not all the "parameters" are available from all "steps"
- In each ECMWF Public Dataset not all the "steps" are available from all "times"
- 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.
- Tailor CDS-API request as needed and run it following Use the CDS API client for data access to get the requested data.
