ECMWF's Public Dataset Service has been providing access to a number of datasets. With the need to consolidate our data-provision infrastructure, this service is being phased out.
For all datasets listed below, the Public Datasets Service stopped on 1 June 2023.
The access method for the S2S and TIGGE datasets will be transitioned to the new ECMWF Data Store (ECDS).
The ECDS will be officially opened on Tuesday, 9 UTC, 21 April 2026. The intermediate period when you can use both systems (WEB-API and CDS-API) is estimated to finish in one month. Then the access using WEB-API will be no longer possible.
For more information how to use the ECDS, please refer to Using the ECMWF data store - ECDS. You can find there also a link to instructions how to change smoothly from the current WEB-API to the new CDS-API to access the data (User guide for migration of S2S and TIGGE to ECDS).
Whenever possible please switch to the alternative datasets listed in the table below.
Should datasets become available elsewhere, this page will be updated.
For any questions please contact us via the ECMWF Support Portal.
