英文摘要: Abstract(#br)In August 2016, continuous measurements of volatile organic compounds (VOCs) and trace gases were conducted at an urban site in Wuhan. Four high-ozone (O 3 ) days and twenty-seven non-high-O 3 days were identified according to the China's National Standard Level II (∼100 ppbv). The occurrence of high-O 3 days was accompanied by tropical cyclones. Much higher concentrations of VOCs and carbon monoxide (CO) were observed on the high-O 3 days ( p < 0.01). Model simulations revealed that vehicle exhausts were the dominant sources of VOCs, contributing 45.4 ± 5.2% and 37.3 ± 2.9% during high-O 3 and non-high-O 3 days, respectively. Both vehicle exhausts and stationary combustion made significantly larger contributions to O 3 production on high-O 3 days ( p < 0.01). Analysis using...
