Abstract

The pollutants from human activity, especially from the Megacity area, has great influence not only to the health of the resident but also to the change of the chemical composition of troposphere and the global climate. So, it is important to develop the simulation system to estimate the impact of these pollutants to the regional atmosphere. In this research, the comprehensive performance evaluation of simulation system of atmospheric environment for East Asia region was perfomed by using groud-level observation data and aircraft observation data. The simualation system is composed of meso-scale meteorological model (MM5 Version 3.7) and three dimensional chemical transport model (CMAQ version 4.4). Simulation result, especially Ozone, was evalulated with several statistical equations, such as the root mean squared error (RMSE), correlation coefficient (R), index of agreement (IOA), and so on. As a result, our simulation system have good performance during summer season. However, there was large bias of ozone concentration in winter season.
