GFZ Data Services is a research data repository hosted at the GFZ German Research Centre for Geosciences in Potsdam (Germany). This repository is open for research data and scientific software from the Earth and environmental sciences. 

Since 2004, the GFZ German Research Centre for Geosciences assigns Digital Object Identifiers (DOI) to datasets. These datasets are archived by and published through GFZ Data Services and cover all geoscientific disciplines. All data and software are provided with a licence that is indicated on the DOI Landing Pages. 

The data repository of GFZ Data Services makes data citable by assigning DOIs to data and scientific software. To recognise the important role of the data providers, data users should formally recognise data providers, contributors and sources by citing them appropriately. Data with assigned DOI are citable as any other scientific article.
