Flow-chart of the methodology. The main steps leading to the estimation of the three geothermal potential variables are summarized. In the Conversion model training box, “TR” signifies Thermal Resistivity and “ER” signifies Electrical Resistivity. Also, note that some Intermediate boxes appear multiple times (Weather maps, SMAP soil moisture maps, and Terrain variables). In order to avoid repeating the same information, the processing leading to each box is shown once, with a superscript between brackets (e.g., [*]). All the other times the box is used, it is associated with the same superscript with no brackets
