As part of this development, a new data store for the Copernicus Emergency Management Service has been created. The CEMS Early Warning Data Store (EW-DSEWDS) will host all the historical and forecast information for floods and forest fires at European and Global levels. CEMS datasets will be migrated to the EW-DSEWDS, so users are encouraged to download and test data from the new EW-DS EWDS Beta before the system becomes operational from 03 September 2024. The new CEMS Early Warning Data Store Beta (EW-DS EWDS Beta) is now live for testing! |

ECMWF Single Sign-On (SSO) has been extended to all its platforms including the new CDS, ADS, and EW-DSEWDS. SSO allows users to have access to multiple applications by signing in with only one account. It also has other important features in regard to simple management, security, ease of use, and seamlessness.
All users of the new CDS, ADS, and EW-DS EWDS will need an ECMWF account. If you already have one, great. If you do not yet have an ECMWF account, please register with ECMWF to get one.
As a consequence of the single sign-on implementation, your current CDS or ADS login credentials will not work on the new CDS, ADS, EW-DS EWDS infrastructure, regardless of whether you are currently using the CDS or ADS interactively (e.g. over the web interface) or programmatically (using the API service). A new UserID (ECMWF) and API key will be needed.
Your ECMWF account will only allow you to login to the new CDS/ADS/EW-DSEWDS, not onto the current CDS/ADS.
...
Your existing CDS account will only work in the current CDS, not in EW-DS EWDS Beta. You need an ECMWF account to start using EWEWDS-DS-Beta.

EWDS Catalogue - data download over web interface:
- Before downloading any data from the new CDS/ADS/EW-DS EWDS infrastructure, users will have to accept dataset terms and conditions on the new system. Users' profiles including licensing information are not being transferred. In practical terms, this means for example that if you are downloading ERA5 data (web or API) from the current CDS, you will need to login to the new CDS and accept the terms and conditions for ERA5 (i.e. Licence to use Copernicus Products).

- A new version of the cdsapi package has been released. API users need to upgrade their CDS API (i.e pip install --upgrade cdsapi). Note that the new version of the cdsapi package works on both the current and new CDS.
- When EW- DS Beta is open, log in to the EW- DS Beta interface using your ECMWF account and follow the instructions online. Make sure you also accept the Terms and Conditions of the datasets you wish to download (see CDS/ADS/EW-DS EWDS Catalogue section above).
- You will need to update your .cdsapirc file as shown in the first black box displayed on the EW-DS EWDS Beta API page (you must be logged in!).
- Before running your API script to fetch data from EW-DS EWDS Beta, please use the "Show API request code" tool on the dataset Download Form on EW-DS EWDS Beta to check you are using the correct syntax for your API request. CDS/ADS/EW-DS EWDS API syntax is changed and some keys or parameter names may have also changed.

The CDS Toolbox will be discontinued and is not migrated to the new CDS/EW-DS EWDS infrastructure. Support will continue to be provided to CDS Toolbox users until the CDS Toolbox is shut down in September 2024. ECMWF Support will however not be able to help with supporting users migrating their CDS Toolbox workflows onto another programming language/software.

Please send your feedback and/or report any issue/bug you may have encountered while using the new CDS/ADS/EW-DS EWDS infrastructure by raising an enquiry ticket through our dedicated Support Portal (ECMWF login required) - make sure you select "Yes" to the question Is this request related to CDS-beta/ADS-beta/CEMS-EW-beta? on the Support Portal request form - this will help the Support team with triaging enquiries more efficiently.

- New publication of datasets (including publication of existing dataset new versions) will only be made in the new CDS/ADS/EW-DS EWDS infrastructure. Users are therefore urged to migrate over to the new CDS/ADS/EW-DS EWDS infrastructure as soon as possible.
- Some observation datasets will not be immediately available to download from the new CDS infrastructure while technical issues with these particular datasets are being addressed.
- Some unsupported datasets in current CDS will be deprecated in the new CDS infrastructure.
- For the time being, DOIs of datasets in CDS-Beta will point to the same datasets in the current CDS until the current CDS is shut down in September 2024.
- The current CDS and ADS will be completely shut down in September 2024. Please migrate to using the new CDS/ADS/EW-DSEWDS by September 3rd, 2024. Should users still have API scripts pointing to the retired CDS and ADS systems, these will systematically break and no support will be provided.
