In-situ measurements are necessary to provide ground truths for remote observations, to conduct focused investigations on local scales and working as a network to investigate large scale phenomenon and their relation to local scale processes [1]. In this work we are interested in the coupling between the Martian atmosphere and the subsurface in terms of the thermal and mass exchange processes as this is not fully understood yet. A thermal model combined with temperature measurements is a useful way to characterise the subsurface properties [2]. A model is developed that simulates heat transfer through convection and conduction. The model is applied to the temperatures measured by the Viking 1 footpad sensor that was in direct contact with the Martian surface. The sensor is shown to be in shadow and the thermal properties used in the model suggest the influence of the footpad thermal properties.
