Abstract:

Part I of this report describes a method for predicting the cumulative distribution with time of transmission loss at frequencies above 10 megacycles per second over paths of arbitrary length. The method makes use of available information about terrain profiles and surface meteorological data, and is based on the CRPL radio standard atmospheres, in which the radio refractive index decreases linearly with height for the first kilometer above ground, and then decreases exponentially with height 1/. Discussion of the theoretical basis for this formula and a demonstration of its accuracy by comparison with experimental data are reserved for later parts of this report.
