Abstract—To study the global air pollution concentration and evaluate the impact of regional pollution on whole earth, a global atmospheric contaminant transport model is established based on 3D advection-diffusion equation, which captures the processes of advection by wind and turbulent diffusion during atmospheric dispersion. The Eulerian finite difference method is employed for numerical solution of the proposed model. Then one-year aerosol transport on global scale is simulated using the proposed model, and the simulation results are verified against the real remote sensing data of NASA. It turns out that the simulated values of aerosol concentration are strongly correlated with the real values and the correlation coefficient is above 0.8 for sample point. Furthermore, the proposed model is used for predicting the next-year global atmospheric contaminant concentration by simulation.
