Asian dust storms, which can long range transport and pass through the China Sea, often occur on spring. During this process, dust storm makes some impact on marine ecology and region climate, and the present of Asian dust aerosols over ocean takes some difficult for cloud detection, atmosphere correction of ocean color and sea surface temperature retrieval. Study on Asian dust aerosol properties over ocean is the basis of satellite remote sensing, which is a powerful tool to study dust over ocean. In this paper, the optical and thermal properties of Asian dust aerosol are presented by combining the Moderate Resolution Imaging Spectroradiometer (MODIS) observations and Streamer model simulations. By compare, the reflectance of dust aerosol over ocean at the visible band2, band3 and the near-infrared band6 of MODIS have some significant features, which are different from others, it satisfies Rb3
