Abstract

Melting Particle is important to estimate rain fall rate in winter season. There are many studies concerning melting particels relating to radar bright band or changes of dielectric constants, but few studies about quantitative observation.
We observe rain or meteorological elements since July 2003 at IIS, Tokyo by using Micro Rain Radar(MRR, METEK GmbH Germany). MRR is the small, inexpensive instrument that can detect the radar reflectivity of each Doppler spectrum.
In this study, we report the melting situation with comparision MRR observation to calculation of particle melting on 29th December 2004.
