Paper Abstract

In recent years, the bio-optical model has been paid more and more attention. In order to validate its applicability in the near-infrared wavelengths to Case II waters, two simply parameterized equations employing reflectance at 808nm and 873nm were established to estimate total suspended matter (TSM) concentrations in the Shitoukoumen Reservoir that represented a turbid inland water condition. It was showed that both equations gave out comparative good performance with coefficient determination (R2) larger than 0.85 and root mean squared error (RMSE) much lower than data span for both training and test data. Based on the transfer of radiation in waters, the bio-optical model could integrate well apparent optical properties (AOPs) with inherent optical properties (IOPs). However, further investigation is needed to upgrade the bio-optical dataset and to refine the model for the universal applications.
