The Eulerian photochemical dispersion model MARS (Graf and Moussiopoulos, 1991) solves the three-dimensional dispersion equation for chemically reactive species by coupling the vertical diffusion to the chemical reaction mechanism, using a predictor-corrector integration scheme similar to the one proposed by Gear, while the horizontal diffusion and the advection terms are computed explicitly.
