主　　题：VOCs vertical profiles secondary organic aerosol PCA Ozone 

摘      要：As Volatile Organic Compounds(VOCs)are one of the precursors of ozone,their distribution and variable concentrations are highly related to local ozone pollution *** this study,we obtained vertical profiles of VOCs in Shanghai’s Jinshan district on 8 September and 9 September in 2016 to investigate their distribution and impact on local atmospheric oxidation in the near surface *** samples were collected from heights between 50 m and 400 m by summa canisters using an unmanned aerial vehicle(UAV).Concentrations of VOCs(VOCs refers to the 52 species measured in this study)varied minimally below 200 m,and decreased by 21.2%from 100 m to 400 *** concentrations of VOCs above 200 m decreased significantly in comparison to those below 200 *** proportions of alkanes and aromatics increased from 55.2%and 30.5%to 57.3%and 33.0%,***,the proportion of alkenes decreased from 13.2%to 8.4%.Toluene and m/p-xylene were the key species in the formation of SOA and *** component analysis(PCA)revealed that the VOCs measured in this study mainly originated from industrial emissions.
