Public Datasets
The ECMWF Public Datasets service is being decommissioned. The access to most datasets was closed or migrated to a different system in June 2023.
Public access to the remaining two datasets, S2S and TIGGE, is being migrated to the new ECMWF Data Store (ECDS) opened on April 21, 2026. No new users are being admitted — please use ECDS instead.
For the latest updates visit Decommissioning of ECMWF Public Datasets service.
Access to these datasets is provided free of charge. Terms and conditions may apply, please check with each individual dataset.
