WebThe effective earth radius method is an approximation used for modelling refraction effects in the troposphere. Changing the radius of the earth can account for refraction effects. … Webwhere r is the actual earth radius and R e is the effective earth radius. Commonly, the effective earth radius factor, k, is chosen as 4/3.However, at long ranges and with shallow angles, k can deviate greatly from the 4/3. (With no atmospheric refraction, k = 1. An infinite value for k represents a flat Earth). ). The effearthradius function provides two methods …
