Short summary
Surface ozone is a pollutant regulated for public health. This study derived surface ozone trends over South Korea from 2001 to 2021 and highlighted that South Korea has been a nonattainment area since 2010, based on the US EPA standard. However, the occurrences of high ozone condition decreased in spring during the COVID-19 pandemic, partly due to large reductions of ozone precursor concentrations in China and South Korea.
