This page illustrates the procedure to cite the ERA5-Land hourly data from 1950 to present dataset and provide appropriate attribution. This dataset is generated under the framework of the Copernicus Climate Change Service (C3S). For such dataset, the Licence to use Copernicus products only applies.

Use Case: A user has downloaded ERA5-Land hourly data from 1950 to present data from the Climate Data Store to calculate some results that will be presented in an article. The user did not download the data to redistribute it. The user downloaded data for the period 1977-1997 from the Climate Data Store on 23 October 2021.


Step 1 - Check applicable licencesStep 2 - Cite the CDS Catalogue entry (traceable source of data)
Step 3 - Provide clear and visible attribution to the Copernicus programme and attribute each data product used (to accredit the creators of the data)
  • Check the licence(s) → Licence to use Copernicus Products only
  • Acknowledge as indicated in Clause 5 e.g. in the context of this use case, Clause 5.1.2 and 5.1.3 apply and the data was used in 2020. In this case, a typical acknowledgement may be as follows:

The results contain modified Copernicus Climate Change Service information 2020. Neither the European Commission nor ECMWF is responsible for any use that may be made of the Copernicus information or data it contains.

In this case, use the citation provided in the CDS Catalogue entry under "References > Citation and attribution":
