“…A comprehensive dataset detailing the distribution of point rain rate (R0.01 in mm/h) across specific locations across Nigeria, as documented in studies [17,35] in the references, was employed for this study. The dataset includes point rainfall rates from 37 stations in Nigeria between 1998 and 2006, as derived from the Tropical Rainfall Measuring Mission (TRMM) satellite sensors, specifically the Microwave Imager (TMI, 3A12 V6) and other satellite sources (3B43 V6) as outlined in Ref.…”

This study investigates the significant issue of rain-induced signal attenuation in satellite communication, specifically focusing on television receive-only (TVRO) stations operating in the Ku band across diverse Nigerian locations. Utilizing a comprehensive dataset of point rain rate distribution and the ITU rain attenuation model, the study comprehensively assesses how rainfall impacts signal quality. The findings highlight that southern regions consistently display high decibel (dB) values, indicating increased susceptibility to signal disruptions during heavy rainfall, while a comparative analysis between two key satellites, EUTELSAT 36B and INTELSAT 20, consistently favors the former in terms of signal resilience during adverse weather conditions. In contrast, northern regions generally exhibit lower dB values, suggesting a higher degree of signal resilience during rainfall events. These insights underscore the importance of considering location-specific and satellite-specific factors when designing satellite communication systems, emphasizing the need for robust infrastructure and strategic satellite selection to mitigate the effects of rain-induced attenuation. This study provides valuable guidance to engineers and service providers, enabling them to make informed decisions to minimize signal disruptions and enhance overall network reliability, particularly in regions susceptible to rain-induced attenuation.
