Thermal conductivity of a geological unit relevant for shallow geothermal energy use (e.g. bedrock).

Measured electrical conductivity of the groundwater at a defined depth interval or for a single point in depth.

Mean measured groundwater temperature based on surveys.

The average thermal gradient within a given depth interval.

Average temperature below ground level within a given depth interval.
