采用光化学箱模式和光化学格网模式对东京都内NO2浓度高的现象进行了研究。根据监测数据，给出了NO2高浓度日NO、NO2和O3随时间的典型变化规律。光化学箱和光化学网格模型的应用成功地再现了这些变化时，使用典型的排放强度NOx和NMHC从东京市中心地区。模拟结果表明，冬季NO2浓度高（超过日本环境质量标准）主要是由于NO光化学氧化生成NO2所致。
The high concentration of NO2in the Tokyo Metropolitan area was investigated by means of air quality monitoring station data analysis and two numerical models: a photochemical box model and a photochemical grid model. Based on monitoring data, the typical variation with time of NO, NO2and O3for days with high NO2concentrations is presented. The application of the photochemical box and photochemical grid models successfully reproduced these variations when using typical emission intensities for NOxand NMHC from the Tokyo downtown area. Model results revealed that the high concentrations of NO2in winter (exceeding the Japan environmental quality standard) mainly result from photochemical oxidation of NO to NO2.
