that potential photochemical ozone production in Shanghai is NMOC-sensitive. It is presently difficult to predict the impact of future human activities, such as the increase of automobiles and vegetation-covered landscapes and the reduction of aerosol on ozone pollution in the fast developing megacities of China, and additional studies are needed to
ACPD Ozone production in four major cities of China . All four cities suffered from severe ozone pollution At the rural site of Beijing, export of the wellprocessed urban plumes contributed to the extremely high ozone levels (up to an hourly value of 286 ppbv), while the pollution observed at the suburban sites of Shanghai, Guangzhou and Lanzhou was characterized by intense insitu ozone
Ozone pollution in summer was found to be more severe in the Tianjin region than in the Shanghai region, based on either the frequency or the duration of high ozone events. Such differences might be attributed to the large amount of highly reactive NMHCs in Tianjin. Industry related species like light alkenes were of particular importance in both urban and suburban Tianjin, while in Shanghai

On the Origin of Surface Ozone Episode in Shanghai over Yangtze River Delta during a Prolonged Heat Wave Jian-Bin Wu1,4*, Qian Wang2,,Keywords: Ozone; Source apportionment; Process analysis; Heat wave; Shanghai. INTRODUCTION High ozone (O3) episodes are one of the most severe air pollution issues experienced in megacities (Wild et al. 2004; Shao et al., 2006; Streets et al., 2007;
01.01.2017· Ozone production efficiency,On high ozone days, the contributions from local and northern Zhejiang to the average ozone in Shanghai were suggested to be 29% and 20%, respectively, which are consistent with the results (13% to 21%) of CMAQ process analysis by Li et al. (2012a). Using the WRF-Chem model coupled with an ozone tagging method, Gao et al. (2016) studied the source

Ozone and its precursors were measured from 15 June 2006 to 14 June 2007 at an urban site in Shanghai and used to characterize photochemical oxidant production in this region. During the observation period, ozone displays a seasonal variation with a maximum in spring. Observed nitrogen oxides (NOx) and carbon monoxide (CO) reached a maximum in winter and a minimum in summer.
In our research, we found that both aerosol and ozone concentrations were higher in Shanghai under polluted conditions than they were under clean conditions during the summer, but the ozone formation was controlled by VOCs, not by aerosol loading. The decrease in the AOD (SSA) increased (decreased) the surface UV radiation and promoted (inhibited) photochemical ozone production. We also found,
