Research Progress on the Development and Application of Air Quality Models

This paper reviewed the development process of air quality model in China and abroad,the key technology in numerical model of air quality and its application research.The modeling prediction of air quality was currently confronting three major issues：the large uncertainties in air pollutant emission inventory,modeling meteorology conditions especially boundary layer and the physi-cal and chemical processes in the atmosphere.It was proposed that the standardized production and the more precise data of emis-sion inventory could improve the accuracy of emission data with the unified standard in analyzing emission sources,and the multi-di-rection development of measurement methods and the enhancement in both monitoring density and frequency with lab study would be used to build the suitable physical and chemical mechanism for Chinese air environment.By optimizing the parameterization schemes in air quality models and introducing the technology of data assimilation with meteorology and satellite observations as well as the air quality measurement,a unified system integrating air quality monitoring and modeling prediction subsystems would be realized in the multi-platform of application.
