Tropical and subtropical sites are known as areas of intense rainfall, where both satellite and terrestrial links suffer from severe levels of signal degradation. In this study, Butare (2°36′S, 29°44′E) and Durban (29°52′S, 30°58′E), with tropical and subtropical characteristics respectively, are compared at different measurement periods. Rainfall microstructural parameters such as rainfall rate, rainfall Drop Size Distribution (DSD) and radar reflectivity, are examined. It is found that at 99.99% rain availability (or R0.01), these parameters are slightly higher at Butare than Durban. However, specific attenuation computations tend to be higher at Durban compared to Butare, between 40 GHz and 1 THz.
