Short summary

Ambient VOCs were measured at an urban site in Beijing before, during, and after APEC China 2014, when air quality control measures were implemented. PMF was applied to identify the major VOCs sources and their temporal variations. SOAP approach was used to estimate variations of precursor source contributions to SOA . Our results indicate that the stringent air quality restrictions have been successful, and controls on vehicles were the most important measures to VOCs.
