CCCA Data Centre

As a CCCA unit, the Data Centre provides a central national archive for relevant climate data and information, ensuring access to data relevant for climate research as well as to models, research resources, model results, and literature. The data made accessible includes, for instance, observation and measurement data, scenario data, quantitative and qualitative data, as well as the measurement data and findings of research projects. The Data Centre serves also as the data interface for the CCCA Service Centre by providing:

  • centralized access to relevant meta-information on how to use and evaluate the data provided
  • systematic documentation of and access to the findings of Austria-related climate scenarios
  • providing contact information of data authors and experts to provide detailed information on the available data.

By establishing the CCCA Data Server, the CCCA DC is inclined to promote interoperability and collaboration between different science and research communities in order to raise awareness on climate change and serve as a central point for sharing knowledge and resources.

What is the CCCA Data Centre?

The CCCA Data Centre is the Austrian data infrastructure for climate data and information, enabling parties involved to publish and retrieve resources with respect to existing data policies.

What is the goal of the CCCA Data Centre?

To support interoperability and promote collaboration between different climate science and research communities in Austria, reducing data redundancy and loss of data.

How is your data managed?

Once registered, you are allowed to upload data. When uploading, you are required to provide metadata information using a metadata editor, after which the data appears publicly in the data catalogue.

Who can access your data once published in the CCCA Data Server?

When describing dataset metadata, you may decide on the access policy to be applied. The data server has an internal structure allowing the definition of eligible organizations and research groups.

Who can use the CCCA Data Centre?

Everyone is able to view the metadata catalogue, but only CCCA registered members are able to upload data. Download of data depends on predefined user rights.

CCCA Data Server

The CCCA Data Server has a CKAN-based web API. CKAN is an open-source data server platform, providing data management tools facilitating publishing, sharing, search and use of data, thus making available data more accessible and retrievable. The CCCA Data Store Structure describes the technical requirements, functionalities and their implementation architecture.


The first component is the Upload module. Here, data can be uploaded via sftp, rsync or scp using SSH (Secure Shell) or via HTTP. By uploading it, the dataset is physically stored on the Data Centre infrastructure. This step requires an authentication, which means an institution or a person receives personalized access. Optionally, data shall be made available with regard to OGC standards and protocols. This means, for example, composition of INSPIRE conform metadata, a Web Map view Service (WMS), as well as a (INSPIRE compliant) download service (Web Coverage Service - WCS, Web Feature Service - WFS). Using this upload function, the user can find his uploaded datasets in a so called quarantine section.


Describing metadata represents the second step. If the dataset is activated, the user is directed to the CCCA MD editor. When all required fields are filled in and the metadata are saved, this data appears in a “public” section.


The new dataset appears in the MD catalogue represented with its metadata, and can then, with respect to license models, be made available to other users.
