Abstract

The advection diffusion equation (ADE) is solved in two directions to obtain the crosswind integrated concentration. The solution we used Laplace transformation technique and considering the wind speed depends on the vertical height and eddy diffusivity depends on downwind and vertical distances. The two predicted concentrations and observed concentration data taken on the Copenhagen in Denmark were compared.
