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.
