Transport of Atmospheric Pollutants in West Mediterranean Areas: Mathematical Model

Abstract

The main objective of this paper is to present a mass conservative method for solving the one-dimensional equation of atmospheric pollutants transport, based on a finite volume method. In order to avoid numerical diffusion a trapezoid rule with a linear interpolation in the extremes of cells is used to approximate integrals. Air pollution problems can be treated by several techniques, we have used a spatial and time uniform grid, numerical results has been implemented in the computer program ATPOTRANS (Atmospheric Pollutants Transport).
