We invite researchers and data users to contribute to the open evaluation phase of heatflow.world by providing technical feedback and suggestions for platform improvements and extensions. The portal is designed as a FAIR-compliant infrastructure for terrestrial heat flow data, and this phase focuses on assessing its usability, data coverage, metadata completeness, and quality assessment schemes. Input from domain experts is particularly valuable for refining workflows, identifying gaps in datasets, and informing future integration of additional data types such as subsurface temperature profiles, thermal properties, or model-derived constraints. Your feedback will directly support the continued development of a reliable, interoperable, and scientifically robust data resource.

On 8 July 2025, we officially launched the new heat flow research data infrastructure to the public. This also concludes the World Heat Flow Database project (phase one).

On 25 February 2025, we organized the 4th Global Heat Flow Day. Spanning nearly 20 hours of live sessions — from 1:00 a.m. to 9:00 p.m. GMT — this year’s event featured a series of diverse and insightful presentations related to heat flow, covering both technical innovations and scientific applications across continents and disciplines.

During a feedback workshop, we concluded a first stakeholder evaluation process with evaluation and recommendations from experts in geoinformatics, research data infrastructure and geoscience.

A full data release of the Global Heat Flow Database with ca. 50% assessment ratio and assigned quality codes was published.

On 22 February 2024, we organized the 3rd Global Heat Flow Day - this time in the light of the new IHFC quality scheme and its application to heat flow data.

The heat fow community developed the new IHFC standard on data and metadata structure and a new quality scheme.

A full data release of the Global Heat Flow Database with the first assessed data sets was published.

On 23 Feb 2023, we organized the 2nd 24hrs virtual live support session. The session offered an exchange and training format for the 2023 updated database structure.

The 7^th International Meeting on “Heat Flow and the Thermal Structure of the Lithosphere” renewed the successful tradition of the Czech "castle meetings", which were organized by the Geophysical Institute of the Czech Academy of Sciences.

The DFG-funded project (phase one) starts with the development of a new research data infrastructure for heat flow data.

On 22 Feb 2022, we organized a 24hrs around the globe virtual live support session to help researchers get into the assessment of the global heat flow database. The sesseion offered discussion about the new data structure and hands-on expereinces on how to convert heat flow research data according to the new database requirements.

The ILP Task Force VIII on Lithospheric Heat Flow (2021-2026) was granted to Fuchs/Beardsmore/Verdoya/Liu/Harris/Negrete Aranda 

The global collaborative and voluntary assessment was initiated by the IHFC.

At the IHFC meeting in 2019 the commission agreed on a new project of reassessment and redesign of the GHFDB, by checking and validating the available data and setting-up a modern research data infrastructure (e.g. providing doi for data) with a new data portal.
