| Abstract: | A one-dimensional Eulerian model is developed to investigate the effect of physico-chemical parameters on the acidification processes of raindrops. The model is structured to treat the complex cloud's microphysical processes in a highly parameterized fashion. For a 1 h rain event simulation, gas depletion ratios range from 35 to 60%, 40 to 70%, and 25 to 30% for HNO3, NH3 and SO2, respectively. Also, a formula is proposed to predict the rain acidity on the ground using known values of gaseous SO2 concentration, the height of the rain growth zone, and precipitation rate. |
