What is a 'box model' (reservoir model) in biogeochemistry, and what are its two core components?1 / 8

A box model represents a biogeochemical cycle as discrete reservoirs (boxes) — e.g. atmosphere, surface ocean, deep ocean, terrestrial biosphere — each holding a mass M_i of a substance (carbon, nitrogen, phosphorus), connected by fluxes F_ij that transfer mass between reservoir i and reservoir j. The modeler's job is to specify each flux as a function of reservoir state, then integrate the resulting system of ordinary differential equations forward in time.

Why do chemical transport models use operator splitting rather than solving the full continuity equation in one coupled step?

ABecause chemistry has no effect on concentrationBEach process (advection, diffusion, chemistry, deposition) needs a different numerical method, and a single fully coupled solve is far more computationally expensiveCOperator splitting eliminates the need for a chemical mechanismDIt is required by the CFL condition specifically
