Abstract : Eight methods of computing atmospheric refraction of radio rays are discussed with appropriate theoretical background. These methods are: the high-angle, or astronomical, refraction case; the statistial method; the low-angle, or terrestrial, refraction case (Schulkin's method); the four-thirds earth model; the exponential model; the initial gradient correction method; the deprtures-from-normal method; and a graphical method (Weisbrod's and Anderson's method). Sample computations are included for each of the methods. (Author)
