Carbonaceous aerosols such as the equivalent black carbon (eBC), the elemental carbon (EC) and the organic carbon (OC) were monitored at the Seoul Olympic Park site (37.521°N, 127.124°E) during the KORUS-AQ 2016 campaign using a Multi Angle Absorption Photometer (MAAP) and an OCEC Analyzer. Averaged mass concentrations of eBC, EC and OC were presented as 2.46±1.52 μg/㎥, 1.01±0.60 μg/㎥ and 4.85±2.60 μg/㎥, respectively. OC/EC ratio and mass absorption cross-section (MAC) of light absorbing aerosols were calculated as 2.32 and 14.8 ㎡/g, respectively. Diesel OC concentrations were estimated from a source profile of diesel vehicles as well. eBC mass concentrations measured from May 26<SUP>th</SUP> to May 27<SUP>th</SUP>, 2016 showed 40% higher than averaged eBC mass concentrations during campaign period. PM<SUB>2.5 </SUB> concentrations measured in this period were also higher than average PM<SUB>2.5</SUB> concentrations. High eBC concentrations were observed from May 29<SUP>th</SUP> to May 31<SUP>st</SUP>, 2016 and from June 9<SUP>th</SUP> to June 11<SUP>th</SUP>, 2016, possibly due to morning rush hour and the effect of temperature inversion at night. Diurnal variations of eBC, EC and Diesel OC showed a typical pattern of metropolitan area. In the weekend, however, diurnal variations of eBC, EC and Diesel OC mass concentrations were different from those measured in the weekday. It is expected that this study can help to understand the relationship between carbonaceous aerosols in a metropolitan area.
