Eight methods of computing atmospheric refraction of radio rays are discussed with appropriate theoretical background. These methods are: (1) The high-angle, or astronomical, refraction case; (2) The statistical method; (3) The low-angle, or terrestrial, refraction case (Schulkin's method); (4) The four-thirds earth model; (5) The exponential model; (6) The initial gradient correction method; (7) The departures-from-normal method; (8) A graphical method (Weisbrod's and Anderson's method). Sample computations are included for each of the above methods.

A survey of some of the advances in the field of synoptic radio meteorology is presented. The development of representative refractive index profiles for major air mass types is reviewed. Included is a description of several refractive index parameters currently in use by radio meteorologists. Two reduced-to-sea-level index forms developed at the National Bureau of Standards are used to illustrate the three-dimensional structure of a broad-scale storm system traversing the North American continent.
