**Copernicus Climate Data Store (C3S)**
=======================================

This tool is a wrapper to retrieve data from the Copernicus Climate Data Store.

- It allows to retrieve data from the Copernicus climate Data Store.
- Any user willing to use this tool needs to `create a new account <https://cds.climate.copernicus.eu/>`_.
- Set your CDS API Key via: User -> Preferences -> Manage Information"
- Documentation on where to get the CDS API key can be found `here <https://cds.climate.copernicus.eu/how-to-api>`_.
- Compose your request directly on C3S and extract the relevant information, which should be put in the input field "Request" or saved in a file. The format should be, for example::


    import cdsapi
    
    c = cdsapi.Client()
    c.retrieve(
        'reanalysis-era5-single-levels-monthly-means',
        {
            'data_format': 'netcdf',
            'product_type': 'monthly_averaged_reanalysis',
            'variable': '2m_temperature',
            'year': '2020',
            'month': '12',
            'time': '00:00',
            'area': [60, 10, 59.5, 10.5],
        },
        'download.nc')


- Be aware that for being able to download dataset from C3S, users also need to agree to licensing terms for each dataset of interest on the C3S website.
