The legacy CDS and legacy ADS will be decommissioned on September 26, 2024 and will no longer be accessible from this date onwards.
On 26 September 2024, CDS-Beta and ADS-Beta will officially become the new CDS and ADS, with URLs to CDS-Beta and ADS-Beta being redirected to cds.climate.copernicus.eu and ads.atmosphere.copernicus.eu respectively.
If you are a legacy CDS or legacy ADS user and wish to continue downloading data from our Data Stores, you are urged to migrate to the CDS-Beta or ADS-Beta now (refer to our Informative page). From September 26, 2024, CDS and ADS API users attempting to access data using their legacy credentials will see their requests systematically fail, for which no support will be provided.
If you are a CDS-beta or ADS-beta user, from September 26, 2024, there will be no urgency at this time to update the URL in your .cdsapirc. Requests will be automatically redirected from the beta URLS to the proper ones for some time. You will be advised to update the URL in your .cdsapirc file at your earliest convenience (but within a timeframe to be announced). Continue to watch our Forum for further announcements.
The decommissioning date of September 26, 2024 is final and will not be extended.
