Short summary

China has been experiencing rapid changes in emissions of air pollutants in recent decades. NO_x and SO₂ measurements from 2006 to 2016 at the Lin’an World Meteorological Organization Global Atmospheric Watch station were used to characterize the seasonal and diurnal variations and study the long-term trends. This study reaffirms China’s success in controlling both NO_x and SO₂ in the Yangtze River Delta but indicates at the same time a necessity to strengthen the NO_x emission control.
