| 摘 要： | 迭代法解辐射传输方程是较精确的方法之一.描述了一种采用海洋表面反射模型解海洋上空大气辐射传输方程的标量迭代法.该方法在计算中对大气采用动态分层,海洋表面反射模型采用三分量模型-白泡、耀斑和离水辐射.为了验证该方法的正确性,分别采用相同的下垫面情况,把我们计算的结果和用6S、Z.A.程序计算的结果作了比较,并进行了误差分析.比较结果表明该方法计算海洋上空大气辐射强度是精确可行的.

| Abstract: | An iterative radiative transfer code for computing the apparent reflectance in models of the ocean- atmosphere system was described.Although the present code only adopted the scalar quantity to calculate the apparent reflectance,it has lots of advantages.Over ocean surface,reflectances include reflectance of whitecaps,reflectance of the sun glint and reflectance emerging from the water-leaving,which were accounted in this code.So the result of the apparent reflectance of the upwelling diffuse radiation at the top of the atmosphere over rough ocean surface was better.The results of the comparison between the new code with 6S code and Z.A.'s code in computing the apparent reflectance in the same condition are excellent agreeable. |
