Description: This data publication contains the 2024 release of the Global Heat Flow Database (GHFDB) together with quality-assessed dataset. It includes unique heat flow measurements (scattered data), filtered datasets (within 0–408 mW/m², corresponding to 0–3σ), and median values aggregated on a 0.5° × 0.5° grid, provided in CSV and KML formats. Gridded heat flow and standard deviation fields are available as Kriging-interpolated products at 0.5° resolution in WGS 1984 projection (CSV and NetCDF) as well as in North and South Pole Orthographic projections (50 × 50 km resolution). The code is a Jupyter Notebook for Ordinary Kriging interpolation of the heat flow data using the PyKrige library. All data and products are described in detail in Neumann et al. (2026). The data includes: Scattered data: • IHFC_2024_GHFDB_unique.csv: Comma Separated Values (csv) file containing unique heat flow values for every measurement point. • IHFC_2024_GHFDB_unique.kml: KML (Keyhole Markup Language) file containing unique heat flow values for every measurement point. • IHFC_2024_GHFDB_filtered_3_sigma.csv: Comma Separated Values (csv) file containing heat flow value filtered with 3σ (standard deviations from a mean) interval (derived from the data file IHFC_2024_GHFDB_unique.xlsx). • IHFC_2024_GHFDB_filtered_3_sigma.kml: KML (Keyhole Markup Language) file containing heat flow value filtered with 3σ (standard deviations from a mean) interval. • IHFC_2024_GHFDB_05x05_median_3_sigma.csv: Comma Separated Values (csv) file containing median heat flow value for each non-empty 0.5×0.5 degrees grid cell (derived from the data IHFC_2024_GHFDB_filtered_3_sigma.xlsx). • IHFC_2024_GHFDB_05x05_median_3_sigma.kml: KML (Keyhole Markup Language) file containing median heat flow value for each non-empty 0.5×0.5 degrees grid cell. Gridded data • IHFC_2024_GHFDB_05x05_WGS1984_Kriging.csv: Comma Separated Values (csv) file containing gridded heat flow data interpolated by Kriging at a resolution of 0.5×0.5 degrees (WGS 84 projection) • IHFC_2024_GHFDB_05x05_WGS1984_STD.csv: Comma Separated Values (csv) file containing gridded standard deviation data for interpolated heat flow data (WGS 84 projection) • IHFC_2024_GHFDB_05x05_WGS1984_Kriging.nc: NetCDF format file containing gridded heat flow data interpolated by Kriging at a resolution of 0.5×0.5 degrees (WGS 84 projection for Cartesian representation). • IHFC_2024_GHFDB_05x05_WGS1984_STD.nc: NetCDF file containing gridded standard deviation data for interpolated heat flow data (WGS 84 projection for Cartesian representation) • IHFC_2024_GHFDB_Ortho_N.csv: Comma Separated Values (csv) file containing gridded heat flow data interpolated by Kriging at a resolution of 50×50 km (North Pole Orthographic projection) • IHFC_2024_GHFDB_Ortho_N_STD.csv: Comma Separated Values (csv) file containing gridded standard deviation data for interpolated heat flow data (North Pole Orthographic projection) • IHFC_2024_GHFDB_Ortho_S.csv: Comma Separated Values (csv) file containing gridded heat flow data interpolated by Kriging at a resolution of 50×50 km (South Pole Orthographic projection) • IHFC_2024_GHFDB_Ortho_S_STD.csv: Comma Separated Values (csv) file containing gridded standard deviation data for interpolated heat flow data (South Pole Orthographic projection)
