Abstract: In this work, we report a numerical and statistical comparison between Advection-Diffusion Multilayer Method (ADMM) and Generalised Integral Laplace Transform Technique (GILTT) approaches to simulate a radioactive pollutant dispersion in the Atmospheric Boundary Layer (ABL) using micrometeorological parameters generated by Large Eddy Simulation (LES). To better describe the wind profile of the irregular ground level terrain, we considered the wind profile as a solution of the MesoNH model. We performed numerical simulations and comparisons against the data of Angra dos Reis-Brazil field experiments.
