摘要

摘要: 半分析模型是水色遥感反演算法的研究热点,而水体后向散射系数对建立半分析水色反演模型是非常重要的参数.通过对黄海、东海海区的水体固有光学量测量数据进行分析,得到水体总后向散射系数与水体总散射系数的关系为乘幂关系,颗粒物后向散射系数随光谱变化的指数在高低浑浊度水体有很大差异,并初步得到黄海、东海海区水体的后向散射系数与总悬浮物浓度的关系,从而为水色半分析模型建立和水光学辐射计算提供一组散射特性模型.

Abstract: semi-analy tical models are hot topics on ocean color remote sensing, and the backscattering coefficient is one of the important parameters in semi-analy tical algorithms.On the basis of the analysis about inherent optical properties data in the Huanghai Sea and the East China Sea, some characteristics of scattering have been found.The variation of backscat tering coefficients by sediments with wavelengths in highly turbid waters is very different compared with that in low turbid waters.Moreover, the primary relationship between the backscat tering coefficient and the total suspended matter concentration is obtained which can help in the establishment of semi-analy tical models as well as radiative transfer calculation in waters.
