| Abstract: | A one-dimensional, time-dependent Eulerian Model for rain scavenging of pollutants below cloud has been develeps. As the results of model simulations,the vertical profile of pH in rain water and concentratfons of SO, NO, and pH values in rain water at ground level as a function of timeafter the butt of a rain event were given. The Simulations were also Performed to compare the effects of NH, aerosol and raininess on SO, NO and the effects of concentration and vertical distribution of SO on pH in rain water. |
