黄东海表观光学量与固有光学量经验模式研究

Empirical Models Between Apparent and Inherent Optical Properties in the East China Sea and Yellow Sea

表观光学特性和固有光学特性是海洋光学研究领域的两大主要研究内容。文中通过2003年黄东海试验和2007年908专项海洋光学调查所获取的表观光学参数中的遥感反射率Rrs(λ)、水下遥感反射率rrs(λ)、海水透明度Zs、下行辐照度漫衰减系数Kd(490)、固有光学参数中的后向散射系数bb(λ)和水体吸收系数a(λ),建立了区域性、季节性的表观光学量和固有光学量之间的经验模式,并对模式进行了误差分析和改进。

The apparent and inherent optical properties are two main research contents in ocean optical study field. The regional and seasonal empirical models between them were built in this article by using the remote sensing reflectivity in apparent optical property, underwater remote sensing reflectivity, seawater diaphaneity Zs, down-irradiance diffuse attenuation coefficient, back scattering coefficient in inherent optical parameter and water body absorption coefficient obtained in the East China Sea and Yellow Sea cruise in Spring 2003 and in Chinese Offshore Investigation and Assessment cruise （908） in 2007, as well as error analysis were given and the model was improved in the end.
