Description:
Since 1963, the International Heat Flow Commission (IHFC) has been fostering and maintaining the compilation of the Global Heat Flow Database (GHDB). Over time, techniques and methodologies in heat-flow density determination evolved and called for frequent updates of the database. The increasing number of data and their diverse underlying methods also require an adequate and consistent evaluation scheme to assess the quality of the respective heat-flow density determination. Here, we provide the intermediate results of a collaborative, community-driven approach started in 2021 to set-up a new, authenticated GHDB. We document the new basic structure to report heat-flow data to the IHFC and present a newly developed consistent evaluation scheme. The quality scheme, for the first time, combines three independent quality criteria in one combined score, comprising the quantified uncertainty, the methodological quality, and the status of overruling effects. It allows a quick comparison of heat-flow data and reveals missing data or insufficient documentation at one glance. With the new quality scheme, users are enabled toselectappropriatereliable heat-flow values for their specific purpose. The process to screen and update incomplete, wrong or empty database entries is ongoing and will last for a couple of years. The most recent intermediate update – the data release 2023 – contains data generated between 1939 and 2022. The data release contains 73,033 heat-flow data from 1,414 publications. 55% of the reported heat-flow values are from the continental domain (n ~40,082), while the remaining 45% are located in the oceanic domain (n ~32,951).
