摘要：This research paper estimates the effects of secondary Radioclimatic variables on signal propagation in Bauchi, Nigeria. Radio Refractivity, refractive index, k-Factor (effective Earth’s radius), Geoclimatic factor and Saturated vapour pressure are important radioclimatic parameters that influence radio wave propagation. The impact of these variables depends on the variation of the measured data of the primary radioclimatic parameters (temperature, relative humidity and atmospheric pressure). The data obtained from Bauchi airport based automatic weather station located between latitudes 90 3 and 120 3 north of the equator. The primary Radioclimatic data used in this study includes temperature, Relative humidity and atmospheric pressure while the Secondary radioclimatic variables includes k-Factor(K), Geoclimatic factor (G), Refractivity (N), refractive index (n) and Saturated vapour pressure (e). The estimated values of K-factor referred to as effective earth radius is less than the global value of (1.333). The closest value obtained was 1.2582 for the year (2020), these values are of indication that Superrefraction effects are possible in the study area and this may lead to possible interference of wireless communication signals. Hence all networks that rely on radio frequency will have distortion of communication within the study area.
