Abstract: The atmosphere is a complex medium. The presence of turbulence in lower atmosphere makes the exchange of matter and energy intense, and the diffusion of air pollutants is evident. It is necessary to obtain the concentration distribution of gaseous pollutants in the lower atmosphere in different regions and heights. The \varphi (NO_x) and \varphi (O₃) were measured during a heavy air pollution episode in Gaocun of Tianjin City from November 25^th to 26^th, 2016 by using ground observation, tethered balloon and aircraft synthetically. The characteristics pollutants at ground, vertical and low-altitude areas were obtained and analyzed combining with meteorological factors. Observation results showed that the level of \varphi (NO_x) on the ground exceeded GB 3095-2012 (the average daily concentration was 230×10^-9), which indicated high pollution level in Gaocun in winter were mainly affected by the local traffic sources. The \varphi (NO_x) decreased with the increase of altitude which was obviously affected by the wind speed, NO_x mainly accumulated below the inversion layer. \varphi (NO_x) at low altitude of urban areas was higher than the suburbs. While in the far suburb of Gaocun, showing \varphi (NO_x) was comparable with the urban areas indicating high local NO_x pollution in Gaocun. The daily maximum 8 hours average concentration of ozone was 8×10^-9. The low ground \varphi (O₃) reflected the low temperature and low photochemical reaction in winter. With the increase of height, \varphi (O₃) showed a rising trend and its vertical distribution was mainly related with temperature stratification. The low-level \varphi (O₃) was higher in the suburbs than that in the urban areas, and the Gaocun concentration was higher than that in the suburbs. The study shows that the increase of \varphi (NO_x) leads to the decrease of \varphi (O₃), which may be related to the low ratio of \varphi (VOCs)/\varphi (NO_x) in the winter of Gaocun, and further analysis is needed.
