Procedure in 3 easy steps

All users of data uploaded on the Climate Data Store (CDS) must provide clear and visible attribution to the Copernicus program and are asked to accredit the creators of the data. This can be achieved by following the 3 steps below:

Step 1 - Acknowledge as per dataset licence

Dataset licences often include an attribution clause. Please carefully check the licence.

If the dataset licence does not contain explicit indication on how to acknowledge the data you still need to provide attribution to the Copernicus program (see Step 2). Otherwise, you need both, to follow the indications provided in the licence and to acknowledge the Copernicus program.

Step 2 - Provide clear and visible attribution to the Copernicus program

To acknowledge the Copernicus program, simply cite the Climate Data Store (CDS) Catalogue entry from where the data were downloaded. That citation can be found on the Catalogue entry  (see Citation under References when available otherwise please contact us) .

Step 3 - Cite the dataset to accredit the creators of the data

You will find the information on how to cite the dataset in the CDS catalogue entry (see Citation under References, when available otherwise please contact us) .

The formatting of the citation can change depending on the journal (or other content provider where you are referencing the data)  requirements. The formatting of the  Citation provided by the CDS is given as an example. 

Terminology: DOI and Citation

It is important to understand the difference between a DOI and a Citation.

The DOI provides a link to a landing page where you can discover the contents it refers to. However, before using the link, the DOI itself does not provide information about the contents. 

The Citation provides information about the contents but does not tell where to find that content.

Obviously, both information are useful and complementary, and usually they are used together when they are both available.
