Simulation of Pollutants with Dry Deposition in the Stable Atmospheric Boundary Layer

An unsteady atmospheric model represented in the atmospheric boundary layer over variable surface terrains. Here the pollutants are chemically reactive primary pollutants and are emitted from an elevated line source into a stable atmospheric boundary layer. The source of pollutants is considered as Floor function type. The time dependent model obtained through an analytical solution from a multiple Inverse Lap lace transform of the atmospheric diffusion equation with the parabolic diffusion coefficient (exchange coefficient) and the wind velocity taken to be of three different types’ viz. constant, constant shear and parabolic functions of vertical height. The pollutants considered to be of chemically reactive primary pollutants emitted from a time-dependent (floor function type) line source. In order to facilitate the application of the model the results for the general situation that includes chemical reaction rate, dry deposition rate & time dependent (floor function) line source incorporated in the mode.
