[Abstract]

　In order to analyze the present status of the atmospheric environment of the Western Pacific region, aircraft observation of atmospheric pollutants over the East China Sea, the Yellow Sea, and the Sea of Japan were made. These missions were performed under collaboration with Korea and China since 1991 as a part of IGAC/APARE activity. Ozone, SO₂, NOx, PAN, aerosols, and acidic gases were measured. Spatial distribution of those pollutants were obtained. Back trajectory analyses clearly showed the impact of emission in the Asian continent including the Korean Peninsula.
