Short summary
Surface ozone levels in urban areas of China were increasing despite the implementation of stringent emission control measures since 2013. Our modeling results show that the decrease in NOx, SO2, and PM emissions and increase in VOC emissions contributed to the urban ozone increases due to the nonlinear ozone chemistry and complex aerosol affects. VOC reduction measures should be implemented in the current and future policies to achieve the goal of improving the overall air quality.
