摘要:The origin of Suspended Solid (SS) in brackish lakes is mainly divided into the plankton in water, fine clastics with terrestrial organic fragment in river water, and reworked sediments from lake bottom. Total Organic Carbon (TOC) content and mass ratio of Carbon to Nitrogen (C/N ratio) in the suspended substance in the lakes have been known to be different depending on the origin. It is expected that the origin of the Suspended Solid can be estimated by the TOC content and C/N ratio measurements. A feasibility study is conducted to estimate the TOC content and the C/N ratio of a brackish lake by using a series of data measured by a spectroradiometer, and the possibility to estimate the origin of SS is studied. Four types of wavelength selection are attempted for multiple regression analysis to estimate TOC content and C/N ratio, including the simulation of SGLI sensor planned to be onboard the GCOM-C satellite. As a result, it is found that the origin of the SS in the brackish lake can be estimated to some extent by multi- spectral visible remote sensing of TOC content and C/N ratio
