Abstract
Description
The surface refractivity(SF) is essential in estimating the performance of terrestrial
radio links. In the troposphere, there are lots of meteorological updraft and downdraft that
influence the refractive index. In this study, we examine the seasonal variation of an emerging
community in Lagos to design a reliable and efficient radio communication system based on
the meteorological parameters.Thirty-nine years dataset between 1980-2018 was used to
examine both the surface refractivity and the meteorological drivers that determine the SF
patterns. It was observed that early wet season and late dry season were seen to have higher
SF values, i.e., 262.03 N-unit and 262.07 N-unit respectively, while early dry and late wet had
lower SF, i.e., 261.71 and 261.76 respectively. It is now possible to use the weather forecast to
predict the likely SF pattern over the tropics.
