Abstract

The spectral data and numerical analyses of the Taihu Lake during the period of October 4-8, 2010 were used to analyze the influence of solar zenith θ, the ratio of scattering and absorption coefficient b/a and parameter Q upon the variation of remote sensing reflectance. According to the results, remote sensing reflectance increases with solar zenith θ, while θ changes in the range of 0°~20° or 80°~89°, which has little influence on the growth of remote sensing reflectance. Remote sensing reflectance increases with the increase of b/a, and there obviously exists a positive relation between them. When Q is large (6~7), its alteration has little effect on the variation of remote sensing reflectance. On the contrary, when Q is small (2~3), its variation has enormous impact on the growth of remote sensing reflectance. Remote sensing reflectance tends to decrease with the growth of Q.
