摘要
<正>Tropospheric ozone(O3) is a trace gas of great significance for air quality and climate change. In recent years, due to the extensive implementation of emission reduction policies, the concentration of fine particulate matter in many countries has decreased significantly [1]. In contrast, the global ground-level O3 concentration has increased by approximately 0.25 ppbv/a [2].
