**Copernicus Atmosphere Data Store (ADS)**
=======================================================================================================

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

- It allows to retrieve data from the Copernicus Atmosphere Monitoring Service.
- Any user willing to use this tool needs to `create a new account <https://ads.atmosphere.copernicus.eu/user/register?destination=/api-how-to|>`_.
- Set your CADS 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/api-how-to>`_.
- Compose your request directly on Copernicus Atmosphere Data Store and copy/paste it in the input field "Request" or save it in a file.
- Be aware that for being able to download dataset from ADS, users also need to agree to their term of use (Licence to use Copernicus Products) on the ADS website.
