| Abstract: | By using the in situ measured data of spectral reflectance and water quality parameters in Aug.22-24,2009,this study analyzed the spectral characteristics and affecting factors of diffuse attenuation coefficient(Kd) of the Three Gorges Reservoir,and built a retrieving model of Kd(490)at band 490nm.In addition,Kd(490)was inversed by using CCD image of HJ-1 satellite in July 21,2009.The results showed that the attenuation peaks were not distinct at bands 440nm and 675nm owing to the high content of non-pigmen... |
