| Abstract: | An atmospheric diffusion model for gaseous pollutants emitted from a continuous point source has been developed. Pollutants concentrations are obtained by solving numerically (implicit finite‐difference scheme) unsteady state one‐dimensional atmospheric transport‐diffusion equations. The surface dry deposition, gravitational settling and leakage of pollutants from the inversion layer are taken into account in the model. |
