Impact model: 3D-CMCC FEM

The 3D-CMCC FEM is hybrid between an empirical and a process-based model relying on the concepts of the LUE approach at canopy level for carbon fixation. The 3D-CMCC FEM is designed to simulate forest ecosystems at flexible scale (from hectare to 1 km per 1 km) and on a daily time step. The model simulates tree growth as well as carbon and water fluxes, at species level, representing eco-physiological processes in heterogeneous forest ecosystems including complex canopy structures.
