Aerosol‐type detection from satellite remote sensing is difficult but an important challenge for improving the estimation of aerosol radiative forcing. In this paper, we have classified aerosols into four major aerosol types, that is, soil dust, carbonaceous, sulfate and sea salt aerosols using SeaWiFS four‐channel data. The retrieved results show that the East China Sea region was loaded with different aerosols in a highly mixed condition. We also succeeded in classifying the volcanic plume from Mt. Oyama located on Miyakejima Island as sulfate aerosols.
