The variability and structure of tropospheric refractivity (N) over Nigeria has been studied
using monthly data of pressure, temperature and relative humidity for the period 2004-2006 …

This work studied the hourly and seasonal variations in the tropospheric surface refractivity
(N) over Makurdi (7.74oN, 8.51oE), Nigeria. The results showed among other things that the …

Relationships of the form Y= α+ βX and Y= αXβ (α, β, constants) have been established
between radio refractivity aloft and surface water vapour density (SWVD), in g/m3 over three …

The troposphere's internal processes are complex and exhibit nonlinear trends, which have
a significant impact on the transmission and reception of high-quality signals worldwide …

The accurate knowledge of radio refractive and water vapour density of the troposphere is
important in the planning, budgeting and designing of transmission and reception of …

Vertical radio refractivity gradients are essential for monitoring propagation conditions when
designing and planning terrestrial radio links for communications in the lower atmosphere …

Tropospheric radio wave signals experience loss due to multipath effect, scattering and
other forms of attenuation through the atmospheric medium, primarily due to variations in …

The investigation of day to day and seasonal tropospheric radio refractivity variation was
carried out in Lagos using a three year period (January 2014 to December 2016) surface …
