Knowledge of heat flow is fundamental for understanding the lithospheric structure and heat-transfer processes. The International Heat Flow Commission (IHFC; www.ihfc-iugg.org) of the International Association of Seismology and Physics of the Earth's Interior (IASPEI) has been fostering the compilation of the Global Heat Flow Database (GHFDB) since 1963. Periodic revisions of the GHFDB have been carried out to update heat-flow data and the scientific methods. Since the last significant development of the GHFDB structure took place in 1976, with limitations of 80-character maximum length for each data, digitization, the evolution of database concepts and technologies and new ways of digital work and research demands for a reconstruction of the GHFDB. A new database structure was just launched in 2021 (Fuchs et al., 2021), including 56 individual fields, grouped in four main thematic groups, heat-flow density, metadata and flags, temperature, and thermal conductivity. The significant improvement over the former heat-flow database structure is the implementation of a parent-child system for heat-flow data determined at each location and an extended set of meta data fields, relevant to enable quality control, and supporting interoperability following FAIR and open data principles. Based on the presented new structure, a reconstructed database will be published as a data publication (Fuchs and Global Heat Flow Compilation Group, 2021) providing the ground for a global reassessment of historical heat-flow data.
