Geoscientific Model Development Discussions,None,1-65,2024 WebPermafrost models are either developed as stand-alone algorithms or as modules that are incorporated into Land Surface Models (LSMs) and General Circulation Model (GCMs) [ 34 ]. One such LSM is ORCHIDEE (ORganizing Carbon and Hydrology in Dynamic EcosystEms). This model is designed to represent terrestrial fluxes (carbon, water and energy budget). WebFigure 1b illustrates how ORCHIDEE (ORganizing Carbon and Hydrology In Dynamic EcosystEms: the land-surface model) represents the surface water budget. Rainfall is partitioned into interception by the canopy and through-fall rain. Through-fall rain, snow melt, dew and frost fill the soil.
