Mechanisms of O3 and PM2.5 evolution along the cold wave passage in Eastern China

Abstract Cold wave (CW) systems in China, driven by strong northerly winds, typically clean the atmosphere but can also transport pollutants. However, elevated PM2.5 and O3 levels often precede CW events, with key processes remaining unclear. This study analyzes over 2000 in-situ observations (2014–...
