Research on Suspended Matter Concentration Retrieval of SDGSAT-1 Satellite in Lake Taihu Based on Hydrolight Model
The use of satellite remote sensing inversion of suspended matter concentration in water bodies is of great significance in water quality monitoring and protection. In the process of suspended matter concentration inversion, it is technically difficult at present to avoid or minimize the interference of chlorophyll-a and colored dissolved organic matter (CDOM) in the water body. Aiming at the "Sustainable Development Goals scientific satellite 1" (SDGSAT-1) MII sensor and using the Hydrolight radiative transfer model, the article theoretically excavates the inversion factor that is only strongly related to suspended matter, constructs an inversion model of Lake Taihu suspended matter concentration suitable for MII images, and applies the model to both measured and sensing image data for verification. The results showed that: the inversion factor
