The Anmyeondo Global Atmosphere Watch (GAW) station has played a vital role as a background site for monitoring air pollution and climate change in Northeast Asia. This study examines the association between air quality at the station and that in other domestic regions of Korea during periods when land breeze prevails at the station. We analyzed the spatial correlations between OC, EC, PM<sub>10</sub>, O₃, NO₂, CO, and SO₂ measured at the GAW station and air quality standard pollutants (PM<sub>10</sub>, PM<sub>2.5</sub>, O₃, NO₂, CO, SO₂) observed at other regions in South Korea (Airkorea) for two periods when data are available at the Anmyeondo GAW station, from June 2017 to March 2019 and from September 2022 to September 2023. The concentration of PM<sub>10</sub> and gaseous pollutants observed at Anmyeondo exhibited positive correlations with those in the western coastal regions of Chungcheongnam-do and Jeolla-do. These spatial distributions likely reflect similarities in regional emission characteristics and/or the influence of meteorological conditions between Anmyeondo and neighboring areas. Under land breezes conditions at Anmyeondo, OC and EC concentrations were positively correlated with PM<sub>2.5</sub> in the western coastal regions of Chungcheongnam-do, western Gyeonggi-do, and Jeolla-do, and with NO₂ and CO in western Chung- cheongnam-do, Seoul, and Gyeonggi-do. Given that traffic emissions were major sources of NO₂ and CO in Seoul and Gyeonggi-do, this results suggest that parts of OC and EC which can be emitted from road traffic sources were likely transported to Anmyeondo under land breeze. Spatial correlation patterns between carbonaceous aerosol (OC and EC) at Anmyeondo and PM<sub>2.5</sub>, NO₂, and CO in other domestic regions were broadly consistent. Notably, rather than OC, EC showed the stronger correlations with these pollutants, reflecting its predominant origin from combustion processes, particularly vehicular emissions, whereas OC was derived from more diverse sources and processes. This findings will help improve our understanding of the factors influencing air quality at the station during periods dominated by land breeze.
