An evaluation is made of the effect of refractive bending in the troposphere on the propagation of high frequency HF radio waves. The index of refraction in the troposphere is defined in terms of the CRPL Reference Refractivity Atmosphere - 1958. The electron density in the ionosphere is represented by a Chapman model. Ray tracing are performed based on the assumption that the propagation media are stratified into layers of constant refractive index. The ground scatter distance and the true and virtual reflection heights are calculated as a function of surface refractivity and various electron density profiles.
