| description | The increasing Ozone (O<sub>3</sub>) concentration in various regions of China has garnered significant attention, highlighting the need to understand the mechanisms of O<sub>3</sub> formation. This study focuses on the source apportionment of O<sub>3</sub> in Jilin City during and after the COVID-19 lockdown countermeasure, and also the influence of anthropogenic emissions on O<sub>3</sub> concentration. The contributions of different O<sub>3</sub> emission sources were quantified using the Weather Research and Forecasting Community Multi-Scale Air Quality (WRF-CMAQ) model in conjunction with the Integrated Source Apportionment Method (ISAM). The results indicate a significant increase in O<sub>3</sub> concentrations during the lockdown in Jilin City, which were particularly characterized by long-distance transportation. Transportation is identified as the primary direct source of O<sub>3</sub> in Jilin City, with Yongji County contributing the most among the six designated regions. This study highlights variations in the causes and sources of O<sub>3</sub> pollution among the different regions of Jilin City. Simply controlling anthropogenic emissions is inadequate for effectively managing O<sub>3</sub> pollution and may even worsen the situation. It is more effective to focus on controlling O<sub>3</sub>’s precursors. These findings improve the understanding of O<sub>3</sub> pollution in Jilin City and provide valuable insights for developing O<sub>3</sub> control policies. Similarly, this research is applicable to other countries and regions. |
