Easy to use air pollution model for turbulent shear flow

Abstract A three-dimensional model for air pollutant dispersion, based on an analytical solution of the advection-diffusion equation, is presented. Vertical and along wind dispersion is described by an analytic solution valid for power law profiles of wind and eddy exchange coefficient while a Gaussian formula describes the lateral one. The model is implemented in GW BASIC MS-DOS for the microcomputer RAINBOW 100 PLUS DIGITAL in interactive mode. The program, easy to use, is listed and an example of the output is given.
