Abstract: The homogeneous- and heterogeneous-heteromolecular nucleation of H2SO4-H2O solution droplets in the stratosphere is investigated and order-of-magnitude nucleation rates are evaluated. The heterogeneous processes considered ...

Abstract: Physical processes which affect stratospheric aerosol particles include nucleation, condensation, evaporation, coagulation and sedimentation. We carry out quantitative studies of these mechanisms to determine if they can ...

Abstract: We have developed a time-dependent one-dimensional model of the stratospheric sulfate aerosol layer. In constructing the model, we have incorporated a wide range of basic physical and chemical processes in order to avoid ...

Abstract: We have performed sensitivity tests on a one-dimensional physical-chemical model of the unperturbed stratospheric aerosols and have compared model calculations with observations. The sensitivity tests and comparisons with ...

Abstract: The homogeneous nucleation theory of liquid droplets in supersaturated vapors is reviewed. Taking into consideration the microscopic surface tension and extrapolating from the triple point to the critical point (T = Te) ...
