Abstract:
Lake scattering characteristics are of great significance for remotely-sensed retrieval model development. In this study, scattering and backscattering coefficients of Lake Chaohu were observed through AC-S and ECO-BB9 meters, and their spectral properties were correspondingly analyzed. Then Power function is utilized to model particulate scattering and backscattering spectra, and spectral slope parameters obtained by simulation are 0.86 and 3.24, separately. The proposed scattering and backscattering models present relatively low predicative errors. Particulate scattering coefficients are closely related to TSM and ISM, with corresponding correlative coefficients of 0.91 and 0.94. Their relationships can be simulated well through linear function, and further specific scattering coefficients of TSM and ISM were proposed to be 0.636 4 (10(-3) m2 x mg(-1)) and 0.910 8 (10(-3) m2 x mg(-1)). In addition, particulate backscattering ratio in Lake Chaohu has a variation range of 0.003-0.026, and refractive index varies from 1.02 to 1.06, which displays no large variation spans when compared with that in previous studies.
