详细导出了粗糙海面的反射矩阵、透射矩阵和源函数矢量计算模型,并应用于海洋大气耦合矢量辐射传输数值计算模型PCOART。在此基础上,分别利用粗糙海面瑞利大气矢量辐射传输问题和海洋大气耦合辐射传输问题对粗糙海面模型进行了验证,结果表明,模型计算得到的粗糙海面大气瑞利散射斯托克斯矢量是精确的,且瑞利散射辐亮度计算相对误差小于0.5%。粗糙海面海洋大气耦合辐射传输问题验证结果表明该粗糙海面计算模型是精确的。相对已有的标量粗糙海面海洋大气耦合辐射传输模型,该模型不仅可以获得整个海洋大气耦合系统的辐亮度场,而且可以获得辐射斯托克斯矢量场。

The reflecting matrix,transmitting matrix and internal radiation source function vector of the rough sea surface were deduced in detail,and were applied to the vector radiative transfer numerical model of the coupled ocean-atmosphere system named PCOART. The model was validated by the two rough sea-surface radiative transfer problems,one was the vector radiative transfer problem of the Rayleigh atmosphere,and the other was the radiative transfer problem of the coupled ocean-atmosphere system. The result shows that the model gives accurate simulation for the two aspects,especially with the relative error of Rayleigh scattering radiance less than 0.5%. Compared with the existing scalar radiative transfer numerical model of the coupled ocean-atmosphere system,this model can derive the radiance field and the Stokes vector field for the whole ocean-atmosphere system.
