    Abstract: The Laplace conversion technique was applied to the Advection-Diffusion Equations (ADE) in two dimensions to obtain crosswind integrated normalized concentration, consider wind speed and the vertical eddy diffusivity 'Kz' are constant. Data set used from atmospheric diffusion experiments conducted in the northern part of Copenhagen, Denmark was obs... Show More
