Abstract

Analytical air pollution modeling T. Tirabassi ABSTRACT In this paper we present some advanced practical models that use solutions of the advection-diffusion equation that accept wind and eddy diffusivity profiles that are power functions of the height. The performance of these models has been assessed with success in cases of both ground level sources as well as elevated sources. INTRODUCTION Atmospheric-dispersion modelling usually takes accounts of atmospheric turbulence by means the method based on Pasquill-Gifford classes. These are utilised where the meteorological state of the atmospheric boundary layer is classified in a simple way based on surface measurements, and where the dispersion from a source is estimated by assuming simple formulae for concentration distribution, in which the dispersion parameters depend simply on downwind distance and the meteorological state of boundary layer.
