Introduction

When cds-beta is officially announced to the public, update the introduction text below to include the URL to cds-beta. If ADS is launched at the same time, then include that of ADS-beta also. |
A new Climate Data Store (CDS) and a new Atmosphere Data Store (ADS) powered by a new state-of-the-art infrastructure, referred to as the Common Data Store (CDS) Engine, are soon to be launched.
All layers of the CDS an ADS infrastructure are being modernised: the front-end web interface, the back-end software engine and the underlying cloud infrastructure hosting the service and core data repositories.
What does this mean in practice to current CDS and ADS users?
User account:
ECMWF Single Sign-On (SSO) has been extended to all its platforms including the new CDS and ADS. 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 and new ADS will need an ECMWF account. If you do not yet have an ECMWF account, you may already register with ECMWF.
As a consequence of the single sign-on implementation, your current CDS or ADS login credentials will not work on the new CDS or ADS 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.
| Note |
|---|
Your ECMWF account will only allow you to login to the new CDS/ADS, not onto the current CDS/ADS. You cannot use your ECMWF account to log in onto the current CDS or current ADS. |
CDS/ADS Catalogue - data download over web interface:
- Before downloading any data from the new CDS or ADS infrastructure, users will have to accept datasets 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).
Additional information to come soon.

API Service - programmatic way of downloading data:
- 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.
- You will need to update your .cdsapirc file with your new credentials (key, URL) to be able to download data from the new CDS.
- CDS API syntax is changed and some keys or parameter names may have also changed. To avoid requests failing, please use the "Show API request code" tool on the dataset Download Form on the new CDS to check you are using the correct syntax for your API request.
CDS Toolbox, Viewers and Applications:
The CDS Toolbox will be discontinued and is not migrated to the new CDS infrastructure.
As a consequence of this, the Viewer tool for the following datasets in the CDS will also be discontinued.
New tool packages will be made available (post new CDS launch) to provide software tools for weather and climate workflows that simplify data access, analysis, visualisation and much more.

Feedback and reporting bugs/issues:
Please send your feedback and/or report any issue/bug you may have encountered while using the new CDS and ADS 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.
Good to know
- Data holdings on the current CDS and ADS will no longer be updated a couple of month following the launch of the new CDS/ADS infrastructure.
- New publication of datasets (including publication of existing dataset new versions) will only be made in the new CDS/ADS infrastructure. Users are therefore urged to migrate over to the new CDS/ADS infrastructure as soon as possible.
- Some unsupported datasets in current CDS will be deprecated in the new CDS infrastructure.
- The current CDS and ADS will be completely shutdown in September 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.
