A REVIEW OF THE CURRENT DEVELOPMENTOF ATMOSPHERIC AEROSOL MODELS

The development and utilizations of atmospheric aerosol models are briefly reviewed. The characteristics of some currently used gas-aerosol thermodynamic equilibrium models and the more complicated integrated dynamics-chemistry models are described, which are suitable for urban and regional air quality assessment. Also the complexity in developing a comprehensive dynamic-chemistry aerosol model are discussed, and some aspects for model development and improvement are indicated, which include the mechanism of organic aerosol formation and transformation, aerosol formation and transformation under cloudy or foggy conditions, and the coupling of complicated aerosol physical-chemical model with regional or global models.
