The case Ⅱ waters has complicated optical characteristic and is closely related to human activities in coastal areas. Using remote sensing to monitor water quality of the case Ⅱ waters has attracted widespread attention, becoming a popular topic in the field of oceanography. Due to the importance of suspended sediment concentration (SSC) in indicating water quality, many studies have been focused on the quantitative retrieval of SSC. The inversion algorithms can be summarized as the following three categories: 1) the empirical models established by the relationship between water optical properties and water components, 2) the semi-analytic models combining the empirical models and the physical models, and 3) the physical models
