Global Heat Flow Data Set

The present Global Heat Flow Data Set, compiled by Pollack et al., was a project initiated by the International Heat Flow Commission of the International Association of Seismology and Physics of the Earth's Interior. The new compilation provides a decade update of an earliear 1976 compilation. A description and analysis of the data set appears in: Pollack, H.N., Hurter, S.J., and Johnson, J.R., Heat flow from the earth's interior: analysis of the global data set, Reviews of Geophysics 31(3), 267-280, 1993.

The present data set includes 24,420 heat flow values at 22,182 sites. We believe that the data set includes all data published through 1985, and many data published subsequently. Even after extensive checking for duplicate entries, it is likely that some duplicates remain in the compilation.

This compilation was supported in part by the U. S. National Science Foundation under grant EAR-8716958.

To FTP the Data Set

The global heat flow data set has been turned over the US National Geophysical Data Center (NGDC) for distribution. Click on HERE to ftp the data set from NGDC.

Please be noted that the data set requires approximately 2,297,930 bytes when uncompressed. If you have any difficulty in downloading or uncompressing the data set from NGDC, please send me an e-mail at I should be glad to make the electronic file available at our site for you to ftp it.
