  1. Through a simple form on the "Download data" tab within the main dataset overview page, where you can select model versions, variables and times required.
  2. Programmatic access through the Python CDS API
  3. CDS Toolbox- where you can download data or build you own applications.

Using the 'Download Data' tab on the Climate Data Store

You can watch this quick video tutorial on how to access CEMS-Flood data using the CDS 'Data Download' tab on YouTube.

Or follow the step-by-step guide below.

  • On the CDS homepage, enter the dataset of interest into the search bar. You can search by all, dataset, application, or provider. 

  • The next page lists the datasets returned for your search criteria. You can narrow your search by using the filters on the left-hand side. In this example, we narrowed the search with 'Spatial Coverage' = 'Europe', and 'Provider' = 'Copernicus CEMS'.

  • Click on the heading of the dataset you are interested in. In this example, we chose 'River discharge and related historical data from the European Flood Awareness System'.
    On the 'Overview' tab you will see details such as the data description and technical information about the data, for example, variables, coverage, resolution, etc. On the right side you will see a list of links with supporting documentation and links to related datasets.
    On the 'Documentation' tab you will see a list of links to relevant documentation, e.g. CEMS-Flood wiki pages, web interface, etc.

  • Click the 'Download tab'. This will bring you to the CDS online download form for your chosen dataset.
    Select the options using the radio buttons. Make sure you make a selection for all mandatory fields.
    At the bottom of the page you will then see a button labelled 'Submit Form', click to download your data selection. (Note: You must create an account on the CDS or Login to download data).
