Welcome to the TRR228DB

The TRR228DB is the project-database of the DFG-funded Transregional Collaborative Research Centre 228. The database is able to archive and provide all research data that are created by the project participants. This includes measured/modeled data, reports, presentations, publications, and pictures. In addition, purchased geodata is available for the project participants. All data is provided with correponding metadata. Depending on the respective rights, the download access may be restricted.
