Abstract

Physical approaches in microwave remote sensing to measure non-spherical frozen hydrometeors are frequently parameterized as spherical particles, assuming either dielectric mixing approximation or equivalent spheres, to make Mie-theory applicable. However, the applicability of those simplified approximations in millimeter-wave radar and radiometric remote sensing of frozen hydrometeors need to be evaluated. This study evaluates those fast approximations by comparing with single scattering parameters calculated by the Discrete Dipole Approximation (DDA) method.
