Dear EWC user,
Following buckets are accessible from the new endpoint:
- seviri-meteosat-41-5-degree.fcdr.level15.netcdf
- seviri-meteosat-45-5-degree.fcdr.level15.netcdf
Users currently accessing the mentioned buckets should update their configuration to use the new S3 endpoint:
https://s3.r1.cloud.eumetsat.int
The previous endpoint will be disabled by 03/07/2026.
No service interruption is expected, and all standard S3 operations will continue to function normally. If you encounter any issues after switching to the new endpoint, please be in touch via https://chat.europeanweather.cloud or https://support.europeanweather.cloud
Kind regards,
EWC Team at EUMETSAT
Dear EWC user,
General information for all EUMETSAT data buckets
As part of the ongoing cloud migration on the EUMETSAT side of the European Weather Cloud, we have started migrating the data buckets listed on the following https://confluence.ecmwf.int/pages/viewpage.action?pageId=488063253. You will notice that a new column indicating the S3 endpoint has been added. This column will be updated as soon as each dataset becomes fully available on the new cloud infrastructure. In general, the migration does not affect the content of the buckets, only the endpoint used to access them. Whenever a dataset is migrated, we will issue a dedicated announcement as part of this series. The buckets with the new endpoint are still accessible from old cloud.
seviri-meteosat-0-degree.fcdr.level15.netcdf bucket accessible from the new endpoint
Users currently accessing the bucket s3://seviri-meteosat-0-degree.fcdr.level15.netcdf should update their configuration to use the new S3 endpoint:
https://s3.r1.cloud.eumetsat.int
The previous endpoint will be disabled by the end of the week.
No service interruption is expected, and all standard S3 operations will continue to function normally. If you encounter any issues after switching to the new endpoint, please be in touch via https://chat.europeanweather.cloud or https://support.europeanweather.cloud
Kind regards,
EWC Team at EUMETSAT
Dear all ,
Due to the s3 storage space in the current EUMETSAT side of the EWC reaching its allowed limits, we had to take the bucket seviri.meteosat-rss.level-15.netcdf offline. This action is required to ensure service continuity and to prevent capacity‑related disruptions on the EUMETSAT side of the European Weather Cloud. The same data are available in https://data.eumetsat.int/product/EO:EUM:DAT:0962 and also in reprojected version `seviri.meteosat-rapid-scan.opera-seviri-level-15.netcdf` covering the period of 2018-2023. If you need the removed data in your activities via EWC S3 bucket, please be in touch via https://chat.europeanweather.cloud or https://support.europeanweather.cloud
We apologies for the short notice. If you currently rely on this dataset, please let us know so we can support you.
Thank you for your understanding, and please reach out to the EWC support team if you have any questions or concerns.
Kind regards,
EWC Team at EUMETSAT side
Dear all,
We would like to inform you about an upcoming scheduled maintenance window on the EUMETSAT side of the European Weather Cloud. The maintenance will take place from 22 June 2026, 06:00 UTC to 26 June 2026, 14:00 UTC.
This intervention is required to perform a major upgrade of the underlying Ceph storage system. No service interruption is expected, and all existing virtual machines and services should continue to operate normally throughout the maintenance.
While we do not anticipate user‑visible impact, there may be occasional periods of reduced performance or slower operations due to temporary load on the storage nodes during the upgrade. We recommend keeping an eye on workflows that are particularly sensitive to I/O performance.
We appreciate your understanding and cooperation. Our team and the cloud provider will be closely monitoring the environment during the entire maintenance window.
For updates during the maintenance, please refer to the Service status | The European Weather Cloud.
Best regards,
EWC Team at EUMETSAT
Dear all,
EUMETSAT EWC R&D Projects should be scientific or technical studies to improve the use of EUMETSAT data or products. They have to provide benefits to EUMETSAT Member States through the broad applicability of the project results, and to be of interest to the general scientific community.
EWC R&D Projects provide access to the operational European Weather Cloud service. Public institutions from Member and Cooperating States may apply via the EWC R&D application form: https://ec.europa.eu/eusurvey/runner/EUMETSAT_EWCCall.
For further information on this opportunity and all details on the application process, please check the https://user.eumetsat.int/news-events/news/european-weather-cloud-research-and-development-call.
If you miss the 30 June deadline, you could still submit a "fast-track" via the same form as soon as you can, but the total amount of accessible resources will be limited in size.
For more information on this call and EUMETSAT data, contact our User Service Helpdesk https://www.eumetsat.int/contact-us.
ECMWF Special Projects have been renamed to European Meteorological Infrastructure Research and Development Projects (EMI R&D Projects).
From 2024 EMI R&D Projects, beside the HPC resources, also have the access to the operational European Weather Cloud service.
EMI R&D Projects are defined as 'experiments or investigations of a scientific or technical nature, likely to be of interest to the general scientific community'.
Users within one of ECMWF's Member or Co-operating States may apply for resources as a EMI R&D Project. This possibility is particularly, but not exclusively, suitable for projects which are undertaken in co-operation between several institutions, nationally or internationally.
If you are interested in this service, please indicate your resource requirements and add a section outlining your intended usage to your EMI R&D Projects request.
For further information on this opportunity and to submit the applications, see: The EMI R&D Projects application page.
If you miss the 30 June deadline, you could still submit a "late request" via the dedicated form as soon as you can, but the total amount of accessible resources might be limited in size.
If you have any questions before submitting the application, please email special_projects@ecmwf.int.
