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 is transitioned to the new ECMWF Data Store (ECDS) 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.
Be aware that we are gradually reducing available WEB-API slots in favour of CDS-API ones as a part of the migration.
For more information how to use the ECDS, please refer to Using the ECMWF data store - ECDS.
Instructions how to change smoothly from the current WEB-API to the new CDS-API to access the data are available in 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.
