Abstract
Abstract Black carbon(BC) aerosols were monitored at the KIST site(37.603°N, 127.046°E) and Cheonan-KOREATECH site(36.766°N, 127.281°E) during the pre KORea-US Air Quality Study(KORUS-AQ) campaign using a couple of Muliti Angle Absorption Photometers(MAAP). BC mass concentrations were presented as 2.14μg/m± 3 1.06 and 0.94±0.60 μg/m 3 at KIST site(Seoul) and KOREATECH site(Cheonan), respectively. BC mass concentrations measured at KIST and KOREATECH sites from 22:00 on May 22 to 12:00 on May 23, 2015 showed 80% and 72% higher than average BC mass concentrations measured during campaign period, respectively. It indicates both sites could be influenced by a remote source. Similar patterns of BC concentrations between two sites from 20:00 to 24:00 on June 6, 2015 implies that the BC could be transported into both sites and then be stagnant inside the Korean Peninsula. Diurnal variation of BC in weekdays and weekends were also presented for the KIST and KOREATECH sites. Morning rush hour peak was observed at KIST site located in metropolitan area though no distinct morning rush hour peak was not observed at KOREATECH site located in a suburban area. This study revealed transport pathways of BC near the Korean Peninsula using back-trajectory analysis of BC measured both in a metropolitan area and in a suburban area.
