The surface temperature forcing is responsible for the majority of the observed deviation of temperature with depth. In some cases, differences higher than the error of measurements are observed between the model and measurements. These can be an indication that other factors than surface temperature change influence subsurface temperature. Groundwater flow is one of the possible candidates.
