Ozone concentrations and meteorological factors in four coastal areas of China (the coast of Fujian Province (c-FJ), the coast of Yangtze River Delta region (c-YRD), the coast of Shandong Peninsula (c-SD) and Beijing-Tianjin-Hebei (c-BTH) in July of 2015-2022. Totally 25 coastal cities were picked as typical cities representative of the studied regions (Ningde, Fuzhou, Putian, Quanzhou, Xiamen and Zhangzhou in c-FJ; Wenzhou, Taizhou, Ningbo, Zhoushan, Jiaxing, Shanghai, Nantong, Yancheng and Lianyungang in c-YRD; Rizhao, Qingdao, Weifang, Weihai, Yantai and Dongying in c-SD; Cangzhou, Tianjin, Tangshan and Qinhuangdao in c-BTH) and the data was averaged to obtain the O3 concentrations and meteorological conditions regionally.
