Abstract:		"The structure of the boundary layer affects the evolution of ozone (O(3)), and research into this structure will provide important insights for understanding photochemical pollution. In this study, we conducted a one-month observation (from June 15 to July 14, 2016) of the boundary layer meteorological factors as well as O(3) and its precursors in Luancheng County, Shijiazhuang (37 degrees 53'N, 114 degrees 38'E). Our research showed that photochemical pollution in Shijiazhuang is serious, and the mean hourly maximum and mean 8-hr maximum O(3) concentrations are 97.9?ª++/-?ª+26.1 and 84.4?ª++/-?ª+22.4?ª+ppbV, respectively. Meteorological factors play a significant role in the formation of O(3). High temperatures and southeasterly winds lead to elevated O(3) values, and at moderate relative humidity (40%-50%) and medium boundary layer heights (1200-1500?ª+m), O(3) production sensitivity occurred in the transitional region between volatile organic compounds (VOC) and nitrogen oxides (NO(x)) limitations, and the O(3) concentration was the highest. The vertical profiles of O(3) were also measured by a tethered balloon. The results showed that a large amount of O(3) was stored in the residual layer, and the concentration was positively correlated with the O(3) concentration measured the previous day. During the daytime of the following day, the contribution of O(3) stored in the residual layer to the boundary layer reached 27%?ª++/-?ª+7% on average"
