Short summary
The emission of pollutants is extremely reduced during the annual Chinese Spring Festival (SF) in Shenzhen, China. To characterize the variation in ambient air pollutants due to the SF, various pollutants were measured in real time in urban Shenzhen over three consecutive winters (2014–2016). The results indicate that reducing emissions of SO2 and VOCs on a regional scale rather than on an urban scale was found to be necessary to reduce urban PM2.5 in Shenzhen.
