DayCent

General ecosystem biogeochemical cycling

Description:  

DayCent is a general biogeochemical model (Parton et al., 1998, Del Grosso et al., 2001a) that simulates daily fluxes of C and N among the atmosphere, vegetation, and soil. The model was derived from the CENTURY ecosystem model (Parton et al. 1987). The CENTURY model is a general model of plant-soil nutrient cycling which has been used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas. CENTURY is composed of a soil organic matter/decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and management and events scheduling functions. It computes the flow of carbon, nitrogen, phosphorus, and sulfur through the model's compartments. The minimum configuration of elements is C and N for all the model compartments. The organic matter structure for C, N, P and S are identical, the inorganic components are computed for the specific inorganic compound.
