Atmospheric refraction is one of the mechanisms through which radio signals propagate in the atmosphere. The refraction of radio signals within atmosphere can be quantitatively investigated using k-factor. For standard atmospheric condition, a value of 4/3 for the k-factor is used for propagation modeling. Weather fluctuates for different places, times and heights, causing changes in the degree of...
Properties of the propagation medium are of crucial importance in modelling the radio communication path. The refractivity of atmosphere decreases with ascending height; enabling beyond-horizon radio communication. Due to different climates in various regions around the globe, no universal equation can be formulated for calculation of atmospheric refractivity at varying altitudes. This paper presents...
