The inversion of inherent optical properties (IOPs) and chlorophyll a (Chla) is one of the key objectives in water color remote sensing. and hyperspectral remote sensing with rich spectral information makes precise inversion possible. In this study. we developed a semi-analytical estimation method for inland water IOPs based on the quasi-analytical algorithm (QAA). https://mabelandfoxs.shop/product-category/cooler-bag/
