A data acquisition system that utilised the open-source Arduino platform was developed to
take real-time ground measurements of primary radio climatological variables of pressure …

This study investigates the influence of the inter tropical discontinuity (ITD) on radio signal
behavior over Nigeria using ERA5 data from the Copernicus Climate Change Services …

Refractivity is a significant challenge of radio signal propagation. As it often distorts or leads
to loss of signals. The seasonal and latitudinal variations of surface refractivity at three …

The quality of services provided via Inter-Terrestrial radio communication links such as GSM
networks, Wide Area Network (WAN), Radio and TV broadcasts is largely influenced by …

The main factor impairing radio wave propagation is atmospheric refraction. To account for
fade margin, a crucial component of a reliable radio link, accurate estimates of the refractivity …

Seasonal cycle of radio refractivity aloft the tropical region have been studied in relation to
the migration of the Intertropical Convergence Zone (ITCZ). Radio refractivity values were …

The incidence of multipath fading in two Nigerian cities is explored in this study utilising the
geoclimatic factor technique and ITUR Recommendation P530-14. Nigerian cities Abuja and …

The vertical distribution of refractivity gradient is important in determining anomalous
propagation condition. Thirty five years of meteorological parameters, obtained from Era …
