Short summary

We introduced three Korea Meteorological Administration (KMA) monitoring stations with monitoring systems and measurement uncertainty. We also analyzed the regional characteristics of CH₄ at each KMA station. CH₄ levels measured at KMA stations are compared to those measured at other Asian stations. From the long-term records of CH₄ and δ¹³CH₄ at AMY, we confirmed that the source of CH₄xs changed from the past (2006 to 2010) to recent (2016 to 2020) years in East Asia.
