The IHFC Global Heat Flow Database

The recent version of the global heat flow database contains about 91,182 data points from 1,586 publications (54,553 from the continental domain and 36,629 from the oceanic domain; status: release 2024; 04/2024). The admission of recent data is in progress - the next update is expected for summer 2025, as the second intermediate result of the data assessment project.

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 2024 compilation, for the first time, contains quality score evaluations according to the IHFC quality codes. A detailed documentation is published here: doi: 10.1016/j.tecto.2023.229976. With the 2024 release, 49 % of data were re-assessed. For the remaining one, data are still missing for a reliable quality evauation. For these, users are still advised to consult the original references and to come to their own conclusion regarding the quality of the data.
