Remote Sensing of Trapping Layer Base Height Using ATIS Transmissions

Abstract

This report describes an experiment that examined the method of determining a trapping layer directly from VHF and UHF radio measurements. The experiment used existing radio broadcasts along the coast of southern California. Some strong correlations between the observed signal strengths and the inferred trapping layer base heights of the various radio paths were shown, indicating the height of the trapping layer is an important factor in controlling radio propagation on over-the-horizon paths.
