Vertical Profiles Of: Rain Drop Size Distribution & Radar Reflectivity Factor-rain Rate (z-r) Relation

Raindrop size distributions and radar reflectivity–rain rate relationships for radar hydrology*

The conversion of the radar reflectivity factor Z (mm6 m-3) to rain rate R (mm h-1) is a crucial step in the hydrological application of weather radar measurements. It has been common practice for over 50 years now to take for this conversion a simple power law relationship between Z and R. It is the purpose of this paper to explain that the fundamental reason for the existence of such power la...

On the Role of Drop Size Distribution in Trmm Rain Profiling Algorithm

The selection of the drop size distribution (DSD) model is one of the critical steps in rain profiling algorithm (RPA) of the NASA Tropical Rainfall Measuring Mission (TRMM) (Iguchi et al. 2000). RPA requires R-Ze and K-Ze relations for convective and stratiform precipitation, where K and Ze represent the attenuation and equivalent reflectivity at 13.8 GHz, respectively, and R is the rain rate....
