You only need to go through this procedure once, before you can use the CDS API on Windows to programmatically download data from either the Climate Data Store (CDS) or the Atmosphere Data Store (ADS).

...

  1. Login to CDS (or Login to ADS)
  2. Copy a 2 line code, which shows a url and your own uid:API key details as followed:
    1. For CDS users, Go to this page and copy the 2 line code displayed in the black box in the "Install the CDS API key" section.
    2. For ADS users, Go to this page and copy the 2 line code displayed in the black box in the "Install the CDS API key" section.
  3. Paste the 2 line code into a  %USERPROFILE%\.cdsapirc file, where in your windows environment, %USERPROFILE% is usually located at C:\Users\Username folder). The CDS API expects to find the .cdsapirc file in your home directory.

    For instructions on how to create a dot file on Windows, please see here or check the instructions provided by one of users on the User Forum.

  4. Install the CDS API client by running the following command in a Command Prompt window:
