Borehole data are direct measurements of temperature from boreholes drilled into the Earth's crust. Departures from the expected increase in temperature with depth (the geothermal gradient) can be interpreted in terms of changes in temperature at the surface in the past, which have slowly diffused downward, warming or cooling layers meters below the surface. A majority of the borehole data at the World Data Center (WDC) are from the University of Michigan's Global Database of Borehole Temperatures and Climate Reconstructions.
