An analytical model of the background stratospheric sulfuric acid aerosol layer
Abstract
An analytical model for the formation of a stationary stratospheric-aerosol background layer is developed on the basis of data on the transformation of carbonyl sulfide (CSO) into H2SO4. Equations are derived for relationships between the characteristics of the aerosol layer and the parameters controlling the process of aerosol formation, such as the rate of CSO injection, the coefficient of vertical transfer of gas and aerosol in the layer, and the average time for the transformation of CSO into H2SO4. A comparison of experimental results with those obtained using the analytical model and those obtained using the numerical model of Turco et al. (1979) showed good agreement with both models, up to a height of 14-18 km above the tropopause (i.e., in the zone where the main bulk of aerosol is observed).
