Land surface processes and energy balance

Webb30 maj 2024 · The surface energy balance (SEB) is an essential cornerstone of any theoretical description of the Earth’s climate system. It can be assessed locally on the ecosystem scale if the turbulent heat fluxes, the soil heat flux and net radiation are measured independently, H + \lambda E + G + Imb = R_ {n} , (1) Webb29 okt. 2024 · This section briefly introduces the energy and water-balance equations normally used in land surface models (LSMs). An LSM of the surface-atmosphere interaction begins with down-welling solar radiation and incoming precipitation, which are the most critical drivers at the terrestrial surface.
