24hrs Global Heat Flow Day
The 24-hour Global Heat Flow Day is an annual event organized by the International Heat Flow Commission (IHFC) to foster scientific exchange among geoscientists, with a particular focus on heat flow research. This event features a continuous 24-hour virtual live session, allowing participants worldwide to discuss current developments, explore new heat flow data, and receive guidance on adapting their research data to meet the requirements of the Global Heat Flow Database (GHFDB). By providing a collaborative platform, the initiative aims to enhance the quality, accessibility, and reliability of heat flow data—an essential resource for geoscientific research.
The inaugural Global Heat Flow Day was held on February 22, 2022, and has since become an annual tradition. During its first three years, the event focused on the global assessment process and the revision of the Global Heat Flow Database, offering participants a forum for discussing the new IHFC data structure and quality scheme (learn more). Starting in 2025, the event has evolved to broaden its scope, addressing a wider range of heat flow research topics and projects. It now features open presentations and webinars, encouraging participants to share insights on measurement techniques, data analysis, modeling approaches, and ongoing research initiatives.
Through Global Heat Flow Day and other initiatives, the IHFC actively promotes collaborative efforts to assess, refine, and update each data entry compiled since 1939. Contributors to this effort are acknowledged as co-authors in future database releases, with the next major update planned for 2025/2026.
The IHFC invites all researchers to participate in Global Heat Flow Day, emphasizing that collective contributions strengthen the quality and impact of global heat flow data—a critical resource for geoscientists worldwide.
