The state-of-art of the GILTT method to simulate pollutant dispersion in the atmosphere

In this work, we present a review of the GILTT (Generalized Integral Laplace Transform Technique) solutions for the one and two-dimensional, time-dependent, advection–diffusion equations focusing the application to pollutant dispersion simulation in atmosphere, assuming both Fickian and counter-gradient models for a wide class of problems. For sake of completeness, we also report numerical simulations and statistical comparisons with experimental data and results of literature.
