Paper Abstract

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.
