Abstract: Dry deposition is the important process of scavenging of gross particle pollutants and sand dust. In this paper, a scheme of parameterization for dry deposition of particle which is fit for the pollution transport model is reached with a “two-layer” surface layer model. It includes the detailed meteorological conditions, the characteristics of surface and the physical and chemical properties of aerosol particles. According to the comparison between the numerical results and observed data, the scheme is reasonable in general, it can describe the main physical processes and mechanics about the dry deposition of the gross particle pollutants.
