Abstract

A mathematical model for the global transport of multicomponent gaseous species and aerosols in the troposphere and lower stratosphere has been developed. The model takes into consideration the main physical and chemical mechanisms (photochemical transformations, binary homogeneous nucleation, condensation/evaporation and coagulation) in charge of the formation and evolution of gaseous species and aerosols in the atmosphere. The model takes into account both anthropogenic and biogenic emissions from the continental and oceanic surfaces. Special emphasis has been made on the formation of nucleation-mode particles from precursor gases. Using the model, numerical experiments to reproduce the spatial and temporal variations of gaseous species and aerosols in the atmosphere over the northern and southern hemispheres for summer and winter months have been carried out.

Keywords:

mathematical modeling, gaseous pollutants, aerosol, global transport, nucleation, condensation, coagulation, photochemical transformation
