A solution of the two-dimensional atmospheric diffusion equation with height dependent diffusion coefficient including ground level absorption

An analytical solution of the two dimensional atmospheric diffusion equation has been developed including effects of ground level absorption. In the model the height dependence of the wind velocity and the vertical turbulent diffusion coefficient is approximated by power functions of z. The deposition correction to the ground level concentration is a universal function of vx high v, were v is proportional to the deposition velocity, x is the distance from the source and v is a stability parameter.
