This geothermal flux dataset was derived from satellite magnetic data and a thermal model. The point data provided were interpolated on to the 5 km grid using spline interpolation. The data unit is mW m-2. Originators: http://doi.pangaea.de/10.1594/PANGAEA.734145 Publisher: Le Brocq, A. M., Payne, A.
