AB: Characterization of the aerosol optical thickness (AOT) and other optical properties is one of the key objectives of satellite observations of atmospheric environment. The quality of satellite aerosol retrieval depends critically upon the modeling accuracy of the physical and optical properties of aerosol such as single scattering albedo, phase function, refractive index, size distribution, and vertical profile. Manny current satellite aerosol retrieval algorithms use a standard vertical aerosol profile assumed in radiative transfer models. LIDAR measurements during ACE-Asia IOP showed that the aerosol profile of Asian dust was multi-layered. SeaWiFS and MODIS data over Gosan, Jeju Island, Korea which was the ACE-Asia super site (33­’17­_N, 126­’09­_E) were used in this analysis along with collocated LIDAR data. Results of satellite data analysis shows that accuracy of SeaWiFS AOT was influenced by the presence of multi-layer aerosol. The results of this study will allow better interpretation of satellite aerosol retrievals and characterization of the radiative impacts of aerosol on atmospheric radiation budget.
