Abstract:
In this work, we develop a splitting characteristic method for solving multi-component atmospheric aerosol spatial dynamics, which can efficiently evaluate aerosol spatial transports by using large time step sizes. The method can compute the multi-component aerosol distributions in high-dimensional domains with large ranges of concentrations and for different aerosol types. Numerical tests show the computational efficiency of the proposed method. An actual simulation focusing on the sulfate pollution is taken in the domain with a varying wind field. We also simulate multi-component aerosol transports in a large area in the southeast of America. The developed algorithm can be applied for the large scale predictions of multi-component aerosols in multi-regions and multi-levels in atmospheric environment.
