Accuracy of radar-based precipitation measurement: An analysis of the influence of multiple scattering and non-spherical particle shape

open access: yesEarth and Planetary Physics, 2018
Two assumptions are typically made when radar echo signals from precipitation are analyzed to determine the micro-physical parameters of raindrops: (1) the raindrops are assumed to be spherical; (2) multiple scattering effects are ignored.
