Soil is arguably the most critical life-supporting compartment of the biosphere, providing numerous ecosystem services from habitat for biodiversity, to food production and key biogeochemical cycles. Soils regulate and support water, mass and energy fluxes between the land surface, the vegetation, the atmosphere, and the deep subsurface, and although major progress in soil models has occurred in the last decades, models of soil processes is not well integrated between disciplines. There is a need to improve exchange of knowledge and experience amongst the different disciplines in soil science and to reach out to other Earth science communities who study land-atmospheric interactions. In this session, we seek contributions that focus on numerical approaches for simulating energy and mass transfer in very near-surface soil environments and the atmosphere. Results of experiments that can be used to support model testing and model intercomparison are also sought.
