Short summary
China has been experiencing rapid changes in emissions of air pollutants in recent decades. NOx 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 NOx and SO2 in the Yangtze River Delta but indicates at the same time a necessity to strengthen the NOx emission control.
