%X Look-up tables of main air pollutants were coupled in our self-developed regional air quality model system RegSRRMS. With the aid of the model, tropospheric air quality over the typical city cluster in China was studied, and the capacity of look-up table method to predict air pollution complex episodes was evaluated. Firstly, based on the state-of-the-art gas phase chemical modules and aerosol modules in WRF-CHEM, a new box model named WRFBOX was built. Secondly, the key physical and chemical factors that may affect tropospheric photochemistry and the formation of aerosols were investigated by using WRFBOX. And then, the look-up tables for photochemical reactions, formation of inorganic aerosols and formation of secondary organic aerosols were constructed by calculating the concentrations of pollutants in various conditions according to these key factors. Finally, the look-up tables were applied in RegSRRMS to simulate concentrations of trace gases and aerosols in Pearl River Delta Region and its surrounding areas during an air pollution complex episode in March 2000. The results showed that the look-up table scheme could not only keep the basic features of atmospheric chemical reactions, but also significantly increase the computational efficiency by saving 57% operation time. Using look-up table scheme in regional air quality models can be propitious to the fast response of air pollution complex in city clusters.
