    Abstract

    C-band dual-linear polarization radar observables are simulated from disdrometer mearurements in rainfall and from gamma-model raindrop-size distributions. It is shown that rainfall is clustered in certain sections of planes formed by selected pairs of radar observables. Measurements lying outside these rainfall cluster regions can be interpreted as being from ice- and mixed-phase hydrometeors. Relationships for estimating rainfall rate R from radar measurements are derived, and the latter is shown to produce the best results. An important problem for C-band measurements in the presence of rainfall is attenuation. For this purpose, relationships are derived for estimating specific attenuation and specific differential attenuation from the specific differential phase. -from Authors
