Comment: moved info on grib and netcdf formats to top of page

CEMS-Floods (EFAS and GloFAS) datasets are openly available on the Copernicus Climate Change Service (C3S) Climate Data Store (CDS). The CDS provides access through web-based and API-based search and retrieve facilities. It is an easy way for users to access climate-related data, including CEMS-Flood data. Access to the Climate Data Store is available via the web at theCopernicus Climate Data Store. 

EFAS and GloFAS data are primarily stored in GRIB format but may be available in NetCDF4 as well, please consult the Data Structure and Formats page for an up to date list of available formats. Follow the links for further information on the GRIB file format and for information on how to read GRIB files.


Warning
titleWarning!

The data service offered by the CDS is not maintained as a time-critical operational service and should not be used for any time-critical operations!

If you would like access to real-time forecast data for time-critical operation please contact us by opening a ticket with the ECMWF Support Portal. A guide on how to do this is provided on the CEMS-Flood User Support page.
