TL;DR: Scattering results from snowflakes generated from aggregates comprised of 6-branch bullet rosette crystals are compared with those obtained from spherical or spheroidal ice-air mixed phase particles and it is anticipated that these findings will have direct implication for the development of the GPM algorithms for estimates of precipitation rate.

TL;DR: In this article, a self-consistent iterative algorithm was proposed to account for rain attenuation of radar and infer the DSD without use of surface reference technique (SRT) is examined by applying it to the apparent radar reflectivity profiles simulated from a DSD model and then comparing the estimates with the true results.

TL;DR: A more rigorous model of the MI return power has been constructed that yields the co-and cross-polarized components of theMI and bistatic returns as a functions of the radar parameters (antenna beamwidth and radar altitude) and the scattering properties of the rain and surface.

TL;DR: In the presence of attenuation, attenuation correction becomes increasingly important at frequencies above about 5 GHz for ground-based radars, where the maximum range within the precipitation is usually much greater than that from air- or space-borne radars as discussed by the authors.

TL;DR: In this article, the vertical profiles of the linear depolarization ratio, LDR (10 GHz), the reflectivity factor, dBZ(10 GHz); and the dual-frequency ratio, DFR (10, 34.45 GHz) were analyzed for measurements taken in stratiform rain in the western Pacific during September 1990.
