A multidimensional model for aerosols: description of computational analogs

Abstract

The numerical algorithms which we use to simulate the advection, diffusion, sedimentation, coagulation and condensational growth of atmospheric aerosols are described. We develop the continuity equation in a generalized horizontal and vertical coordinate system which allows the model to be quickly adapted to a wide variety of dynamical models of global or regional scale. Although our emphasis is on the modeling of aerosols, the work is also applicable to simulations of the transport of gases. -from Authors
