The aim of this work is to present an analytical solution to the three-dimensional advection-diffusion equation in low wind conditions in a stable boundary layer dominated by shear. The model includes the longitudinal diffusion that can not be neglected in low wind conditions. The solution of the advection-diffusion equation is obtained applying the integral transform technique. To validate this methodology, data collected during the classic Prairie Grass experiment were employed. To verify the performance of the model were utilized integral and algebraic eddy diffusivities to parameterize the turbulence. The wind profile is described by power and similarity law.
