titleNew CEMS Early Warning Data Store
typegeneric

As part of this development, a new data store for the Copernicus Emergency Management Service has been created.

https://ewds-beta.climate.copernicus.eu/

The CEMS Early Warning Data Store (EW-DS) 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-DS, so users are encouraged to download and test data from the new EW-DS Beta before the system becomes operational from 03 September 2024.

...

All users of the new CDS, ADS, and EW-DS 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 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.

...

  • 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 Catalogue section above).
  • You will need to update your .cdsapirc file as shown in the first black box displayed on the EW-DS Beta API page (you must be logged in!).
  • Before running your API script to fetch data from EW-DS Beta, please use the "Show API request code" tool on the dataset Download Form on EW-DS Beta to check you are using the correct syntax for your API request. CDS/ADS/EW-DS API syntax is changed and some keys or parameter names may have also changed. 

...

New tool packages will be made available to provide software tools for weather and climate workflows that simplify data access, analysis, visualisation and much more. Please watch the user forum for announcements on this topic in the coming months.

...

CDS-Beta will have some better performing applications including the Copernicus Interactive Climate Atlas and Climate Pulse. More applications will be published including new versions of some applications in the legacy CDS e.g. ERA5 explorer, Global temperature trend monitor...
