MMS一Models一3/CMAQ was applied to simulate the distribution of SO₂,NO₂ and PM in China by taking the January, April, July, October in 2005 for example. The comparison between simulation re- sups and monitoring data show that this model can simulate the spatial distrilxztion patterns of pollutants preferably, simulation results and the monitoring results are identical, especially for the Beijing-Tianjin 一Hebei region, Yangtze river delta and pearl river delta etc.In order to make up for the deficiency of monitoring data, the study applied satellite remote sensing data to the further verification of the simulation result, which include NO₂ column concentration and aerosols optical thickness(AOD).The results showed that experimental results of the CMAQ calculation results were highly correlated to those of the satellite re- mote sensing data; this simulation system is a very good way to simulate the characteristics of the atmo- spheric pollutants in China.
