Analysis of daily rainfall data collected over a period of years is important, especially in the study of rain attenuation of radio waves. This study investigates rain attenuation of radio waves in South-eastern Nigeria which is a tropical location. The daily rainfall data used for this study on Rain Attenuation of Radio Waves in South-Eastern Nigeria was collected from the Nigeria Meteorological Agency (NiMet), Abuja, Nigeria, for a period of 10 years, 1997-2007. The data which was for Calabar (Lat. 4.58°N, Long. 8.21°E), Ikom (Lat. 6.0°N, Long. 8.87°E), Ogoja (Lat. 6.8°N, Long. 8.71°E), Port Harcourt (Lat. 4.51°N, Long. 7.01°E) and Uyo (Lat. 5.02°N, Long. 7.56°E) was subsequently analysed and reduced to obtain rain parameters such as rain rate, R (mm/h), mean annual rainfall, NR (mm), raindrop diameters, Dm (mm), total number of raindrops and rain attenuation, AR (dB). The results of the analysis were compared with those obtained by other researchers and found to be in good agreement. The reduced dip-to-peak values of signal strength observed in our recent studies in South-Eastern Nigeria lend credence to rain attenuation of radio waves in this part of the world. Effects of rain parameters on telecommunication, especially with respect to attenuation, were deduced and they also agreed strongly with literature.
