Chemical compositions of atmospheric aerosols over the Northern and Southern East China Sea were measured using Aerodyne aerosol mass spectrometer. The results showed that the organic concentration was in the same level as the sulfate concentration at Fukue in Nagasaki, while the sulfate concentration was higher than the organics at Cape Hedo in Okinawa. The same tendency was observed by satellite observation. It is inferred that the organic substances influence the cloud formation much stronger in the northern part than in the southern part of East China Sea since the organics were extensively oxidized.
