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 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. For more information or to get involved, contact us.
