MATLAB Functions for Mie Scattering and Absorption, Version 2

Abstract

A set of MATLAB Functions for Mie calculations (Mätzler, 2002a) and for applica- tions to microwave radiation in rain (Mätzler, 2002b) has been improved and expanded by including magnetic and metal-like media and coated spheres. The appendix includes a discussion of the basic behaviour or the Riccati-Bessel and related Functions needed in the computations of Mie Coefficients. The applications of the Mie Functions are directed toward the study of radiative properties of precipitation. Functions have been developed to compute propagation parameters for freezing rain and melting graupel, assuming Marshall-Palmer drop- size distribution, including functions to compute the complex dielectric permittivi- ties of ice and water. Other applications can be envisaged if the dielectric or refrac- tive properties of the particles and their size distributions are known.
