    At upper atmosphere, ozone can absorb ultraviolet and protect life on earth, but at low altitude and near-ground ozone is polluting gas endangering human health, animal and plant growth. Nitrogen oxides are also polluting gases in the air. Ozone and nitrogen oxides can be transformed into each other. Research on the relationship between the two gas is of great significance. Based on EC9810A ozone analyzer and EC9841 nitrogen oxide analyzer, the observation at Chinese Research Academy of Environment Sciences in Beijing during December, 2011 is carried out, and the distributed characteristics of ozone and nitrogen oxide during day and night were obtained. The analysis shows obvious distributed characteristics of ozone and nitrogen oxide during day and night. At daytime, concentration of ozone increases at morning, and then decreases at afternoon. At night, it keeps a steady status and the concentration is less than that in daytime. The trend of nitrogen oxide is opposite to ozone. At daytime, the concentration of nitrogen oxide decreases at morning and then increases at afternoon. The change of ozone has the relationship with meteorology. On sunny day, the concentration of ozone has a sharp increase, but at cloudy day or rainy day, has a slow increase. And the concentration of ozone also changes with the season, it is higher in spring than that in winter. The main reason that results in the concentration increase of nitrogen oxide is the emission of automobile exhaust and other waste gas. AML-3 mobile lidar developed by Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences is used to measure the vertical profile. Variation of mean ozone concentrations from 500 m to 1000 m has a consistent trend with ozone analyzer.
