On assessing haze attribution and control measures in China

Abstract

This paper analyzes the air pollution situation in China, particularly the severe intensifying tendency in central North China. Five major comments on the air pollution issue in China are proposed, emphasizing the scientific understanding on the mechanisms of air pollution formation processes, the interannual variability, the relative roles of climate change and pollutant emissions, the interaction between climate change and atmospheric chemical processes, and the seasonal prediction of air pollution. The viewpoints have significance for air pollution management in China and around the world.
