Analytical solutions of equations are of fundamental importance in understanding and describing the phenomenon of turbulent diffusion in the atmosphere. Focusing our attention in this direction, in this work we report a semi-analytical solution for the three-dimensional advection-diffusion equation in order to simulate pollutant dispersion in the atmosphere considering a vertically inhomogeneous PBL. This work relies on the semi-analytical solution for the three-dimensional advection-diffusion equation combining the ADMM (Advection Diffusion Multilayer Model) and GITT (Generalized Integral Transform Technique) methods. We coin this technique as GIADMT (Generalized Integral Advection Diffusion Multilayer Technique). © 2007 Elsevier Ltd. All rights reserved.
