Estimation of Raindrop Size Distribution Parameters from Polarimetric Radar Measurements
Estimation of raindrop size distribution over large spatial and temporal scales has been a long-standing goal of polarimetric radar. Algorithms to estimate the parameters of a gamma raindrop size distribution model from polarimetric radar observations of reflectivity, differential reflectivity, and specific differential phase are developed. Differential reflectivity is the most closely related ...

Following the first (1991-1993) and the second (1994-1996) TRMM PR teams, and the third international TRMM PR team (1997-2000), the fourth international TRMM PR team (2001-2003) started its job in 2001 based on the NRA-99-OES-03 in 1999 and NASDA-3rd RA-TRMM in 2000. In April 2004, the fourth international TRMM PR team completed the revisions of the standard algorithms to version 6. NASA and JA...
متن کاملRaindrop size distribution estimation from S-band polarimetric radar using a regularized neural network
Radar rainrate estimates are prone to a high degree of uncertainty due to several error sources, among which the space-time variability of the raindrop size distribution (RSD). Polarimetric radar measurements enable the use of combined algorithms which reduce the sensitivity to the variability of the RSD. The aim of this work is to develop a new procedure to retrieve the RSD parameters which ca...
