Due to the fact that the atmosphere is a complex medium, the presence of turbulence in the lower atmosphere causes intense exchange of matter and energy, and the diffusion and transmission of pollutants are obvious. It is necessary to conduct three-dimensional observations of the lower atmosphere at different heights and regions to obtain the most direct data on the concentration distribution of gaseous pollutants. It is necessary to comprehensively utilize ground observation stations, tethered balloons, and aircraft platforms, On November 25-26, 2016, a three-dimensional observation was conducted on NOx and O3 under polluted weather conditions in Gaocun, Wuqing, Tianjin. The distribution characteristics of pollutants in the ground, vertical, and low altitude areas were obtained, and analyzed and studied in conjunction with meteorological factors. The observation results showed that the surface level of NOx was relatively high, with a daily average value of 230 × 10-9, exceeding the limit of the second level standard of GB 3095-2012 "Environmental Air Quality Standard", reflects the high pollution level of Gaocun in winter, mainly affected by local traffic source emissions$ \Varphi $(NOx) shows a decreasing trend with the increase of altitude, and is significantly affected by wind speed, mainly accumulating below the inversion layer. Low altitude $ varphi $(NOx) in urban areas is higher than that in suburban areas, while in more remote suburban areas, Gaocun $ varphi $(NOx) is equivalent to that in urban areas, which also reflects the high level of NOx pollution in Gaocun. Gaocun's ground $ varphi $(O3) is low, with a daily maximum 8-hour average value of 8 × 10-9 reflects the characteristics of weak low-temperature radiation and low intensity of photochemical reactions in winter. As altitude increases, $ varphi $(O3) shows an upward trend, and the vertical distribution characteristics are mainly related to temperature stratification. Low altitude $ varphi $(O3) shows a higher level in suburban areas than in urban areas, and a higher level in high villages (outer suburbs) than in suburban areas. Research shows that an increase in $ varphi $(NOx) leads to a decrease in $ varphi $(O3), This may be related to the low levels of $ varphi $(VOCs)/$ varphi $(NOx) in winter in Takamura, and further analysis is needed in conjunction with VOCs observation data
