The IHFC Global Heat Flow Database

The recent version of the global heat flow database contains about 73,033 data points from 1,414 publications (40,082 from the continental domain and 32,951 from the oceanic domain; status: release 2023; 02/2023). The admission of recent data is in progress - the next update is expected for early 2024, as the first intermediate result of the data assessment project.

Quality:
The database is currently under intense revision. The on-going reassessment of structure and quality of the database is supported and driven by the heat-flow community. Learn more about this process. The current compilation does not contain any descriptive metadata codes that were included in previous compilations. A detailed documentation is in preparation for the next release. Therefore, users are still advised to consult the original references and to come to their own conclusion regarding the quality of the data.
