由于粒子形状的复杂性，精确计算非球形卷云粒子的散射矩阵比较困难。几何光学近似方法是计算非球形卷云粒子光学性质的最常用的方法之一。我们描述的FORTRAN代码来计算一个4乘4的散射矩阵的凸和凹卷云粒子使用几何光学近似方法与夫琅和费衍射理论。还考虑了冰晶面的随机性。散射矩阵的例子。此外，我们从理论的角度讨论了计算非球形粒子的复杂性。
Due to the complex shape of particles, it is difficult to calculate the scattering matrix of the nonspherical cirrus particles exactly. One of the most widely used techniques to calculate the optical property of nonspherical cirrus particles is the geometrical optics approximation method. We describe the FORTRAN code to calculate a 4 by 4 scattering matrix of both convex and concave cirrus particles using the geometrical optics approximation method together with the Fraunhofer diffraction theory. The randomness of the ice crystal face is also considered. Examples of the scattering matrix are presented. In addition, we discuss the complexity of calculating nonspherical particles from the theoretical point of view.
