Model studies of the formation and growth of atmospheric sulphuric acid/water particles

In this thesis, a model which combines gas-phase chemistry and aerosol dynamics has been developed for the formation of sulphuric acid/water particles. The model includes the formation of sulphuric acid in the gas phase, gas-to-particle conversion of sulphuric acid and water (homogeneous nucleation and condensation onto pre-existing particles), coagulation and deposition of particles. Condensation and coagulation determine the growth of particles. The particle size distribution is presented by monodisperse and sectional approaches.
