Joint Seminar: Does Land Surface Model depth matter? Perspectives from global land heat uptake and Arctic soil responses

Land Surface Models (LSMs) resolve the ground surface and subsurface physical components and their interaction with the atmosphere within the Earth System Models (ESMs). State-of-the-art LSMs incorporate a detailed representation of land-atmosphere energy exchanges, water balance, vegetation dynamics, soil moisture, and other related thermodynamical and hydrological processes. However, most current-generation LSMs still impose too shallow subsurface depths (3-40 m), insufficient to correctly represent the propagation of ground surface temperature industrial trend underground. This limitation biases the representation of the temperature vertical profile, affecting the estimated land contribution to the terrestrial energy budget and the evolution of perennially frozen soils, i.e. permafrost, in Arctic regions.
