“…The concentrations of diacids and oxoacids during the LCD increased by factors of 1.1 and 2.1, respectively, while α-dicarbonyls during the LCD were almost the same as before the LCD. The concentrations of diacids and TDOCs reported in this study were significantly lower than those in Xi'an (Cheng et al, 2013), Chengdu (Li et al, 2015), Tianjin (Devineni et al, 2023;Zhao et al, 2023), Liaocheng (Meng et al, 2020), 14 Chinese cities, and other Asian megacities such as Padori, Daejeon (Zhao et al, 2023), Ulaanbaatar (Jung et al, 2010), Chennai (Pavuluri et al, 2010), and Tokyo (Kawamura and Yasui, 2005), but they were similar to those in Beijing (Zhao et al, 2018) and Guangzhou (Ho et al, 2011) during the wintertime (Table S4).…”

“…3b), indicating the stronger photochemical transformation of organic aerosols during the LCD. The C 3 /C 4 ratio before the LCD was lower than that in other Asian megacities such as 14 Chinese cities (Ho et al, 2007), Beijing (Zhao et al, 2018), Daejeon (Devineni et al, 2023), and Chennai (Pavuluri et al, 2010), but it was comparable to that in Tianjin, where biomass burning, biogenic sources, and their aging contributed significantly to diacids and related compounds (Devineni et al, 2023) (Table S4). However, the C 3 /C 4 ratio during the LCD was much higher than that in other Asian megacities (Table S4), again implying significantly enhanced photochemical oxidation during the LCD.…”
