Abstract
Analysis of the simultaneous absorption and chemical reaction of SO2 in water droplets falling in a non-uniform temperature field is extended to include the effects of raindrop size distribution, aerosol scavenging and S(IV) oxidation. Presented results indicate that non-isothermal effects on SO2 absorption by water droplets can be important in gas-absorption calculations and interpretation of ground level samples. For example, for low initial pH rains the effect of rainfall rate on ground level bulk samples is dramatically different than that predicted by isothermal models. Furthermore, in the below-cloud region both SO2 absorption and sulfate aerosol scavenging are shown to impact significantly on the solution chemistry, whereas, the effects of S(IV) oxidation are not important. In addition, simulation results are analyzed in terms of washout ratios and scavenging coefficients; which, in turn, are parameterized by drop size, pH, rainfall intensity and temperature.
