A mathematical model is presented that describes the transport, turbulent diffusion, and chemical reactions of air pollutants in stratus clouds. The chemical kinetic mechanism treats 97 gaseous, heterogeneous, and aqueous reactions between 54 species. The dispersion and night-time chemistry of a power plant plume in a stratus cloud is simulated. The contributions of various chemical pathways to the formation of sulfate and nitrate, the differences between plume and background concentrations, and the effect of reduced primary emissions on secondary pollutants are discussed. Calculated sulfate and nitrate concentrations are commensurate with measured atmospheric concentrations.
