Short summary

Significant decreases in annual mean NO_x from 2011 to 2016 and SO₂ from 2008 to 2016 confirm the effectiveness of relevant control measures on the reduction in NO_x and SO₂ emissions in the North China Plain (NCP). NO_x at SDZ had a weaker influence than SO₂ on the emission reduction in Beijing and other areas in the NCP. An increase in the number of motor vehicles and weak traffic restrictions have caused vehicle emissions of NO_x, which indicates that NO_x emission control should be strengthened.
