Variability of Microwave Scattering in a Stochastic Ensemble of Measured Rain Drops

Remote Sensing, 2018
While it has been proved that multiple scattering in the microwave frequencies has to be accounted for in precipitation retrieval algorithms, the effects of the random arrangements of drops in space has seldom been investigated.
