A boxmodel develpoment to study the relationships between the photo-oxidants and the particles formation in the troposphere

摘要

The model BAGS (Boxmodel for Aerosol and Gasphase Simulations) has been developed It is composed of two major modules: the first one describes the system of the chemical reactions in the gaseous phase the second one calculates the aerosol chemical composition and the dimensional distribution of the particles The boxmodel has been developed wtih the introduction of new chemical and phydical processes not previously inclued in particular the formation of Secondary Organic Aerosol.The other implemented processes are a module for the dynamic of the parmitted to compare it with other models (MAPS and MADM).The tests in particular have concenrned the aerosol water content predication the photochemistry the codensation of hte inoraginic compounds and the formation of Secondary Organic Aerosol.
