Using the trajectory model to simulate the diurnal change of ozone concentration
利用轨迹模式模拟近地层臭氧日变化

It is put forward to use trajectory model in multi\|trajectory in order to simulate the diurnal change of the ozone concentration in specific places.The diurnal change of the ozone concentration in the area of Beijing Yanshan Petroleum and Chemical Industry Inc.was simulated by this method and it is shown that the simulation keeps consistent with the real measurement.Furthermore the local ozone formation character was simulated and the impacts of the local meteorological factors and emissions of pollutants on the formation concentration of ozone were simulated and discussed.The results show that the key of controlling the local photo\|chemical smog is cutting down the emission of NO\- x ,and reducing the percents of alkene and aromatic in the emission of NMHC is also very important.
