Short summary
This study investigated the effect of COVID-19 lockdown (LCD) measures on the formation and evolutionary process of diacids and related compounds from field observations. Results demonstrate that more aged organic aerosols are observed during the LCD due to the enhanced photochemical oxidation. Our study also found that the reactivity of 13C was higher than that of 12C in the gaseous photochemical oxidation, leading to higher δ13C values of C2 during the LCD than before the LCD.
