Scattering and extinction: dependence upon raindrop size distribution in temperate (Barcelona) and tropical (Belem) regions

This paper gives a summary of the salient results derived from experimental campaigns carried out in Belem and Barcelona in 1994. The instrumentation used is briefly described. The research shows that there was no significant differences in raindrop size distribution N(D,R) between the two sites. Both log-normal and gamma distributions are adequate to model the distributions. The N(D,R)-based equivalent radar reflectivity and specific attenuation are given and compared with literature results.
