“…They concluded that 𝜀 ′ did not follow a particular trend as a function of frequency and was texture dependent. Vyas et al (30) and Gadani et al (31) measured 𝜀 ′ and 𝜀 ′′ of Badmer, Pali, Jodhpur and Jaipur districts as a function of moisture content and frequency. Results showed that 𝜀 ′ and 𝜀 ′′ both increased with moisture content at a particular frequency.…”

Dielectric properties of soils are important in the field of geophysical exploration, agriculture, and remote sensing, as these directly affect the performance of electromagnetic sensors. Soils vary from region to region due to variation in texture, temperature, demography, and environment, so area wise dielectric properties of soil differ significantly and depend upon frequency, moisture content, bulk density, and salinity. India has a wide variety of soils and numerous researchers have studied dielectric properties of many states of India. However, due to difference in technique used, frequency of interest, and soil type, it is difficult to generalize dielectric behavior of soils of India as a whole. In this review, we present a systematic state wise analysis of all reported dielectric data on soils of India at radio and microwave frequencies.

“…The effect of hydrometeors on quality of propagation have also been well detailed in literature for tropical regions, some of which include [16, 17, 18, 19, 20 and 21] among others. Wang and Schmugge [22] Vyas [23], and Hallikainen et al, [24], have equally reported that an increase in moisture content in the soil provides a tool to determine soil electrical parameter. The effect of relative dielectric permittivity of soil on AM and FM stations over Southwestern…”

Radio signal transmitting above the ground surface experiences attenuation as a result of absorption by vegetation and hydrometeors, refraction due to turbulence in weather parameters; and reflection from ground surface. In this study, attempt was made to compute surface refractivity from its constituent parameters, and investigate its variation with leaf wetness and soil permittivity, at seven (7) different stations across Ondo state, Nigeria. Data for the research were obtained by in-situ measurement using Davis 3125 Vantage Pro2 weather station having sensors for measuring temperature, pressure, relative humidity, leaf wetness and soil moisture content. Measurement was carried out round the clock at 10 minutes integration time for a period of two weeks at each of the study locations, and for each of rainy and dry seasons. The soil moisture content was obtained at 30cm soil depth while leaf wetness was measured by attaching its sensor directly to a projected leaf-branch; and surface refractivity was computed from pressure, temperature and humidity data. Correlation analysis was employed to measure the strength and direction of the relationship between surface refractivity and each of soil permittivity and leaf wetness. Across the locations, R ranges from 0.38 to 0.9; and 0.04 to 0.7 for rainy and dry season respectively. The value of R is statistically significant at all the stations during the rainy season and majority of the stations during the dry season; signifying that surface refractivity exhibits good spatial and temporal relationship with soil permittivity and leaf wetness across the stations albeit with varying intensities.
