STUDIES OF THE LOWER IONOSPHERE.
Abstract
The work described herein includes several experimental studies of the lower ionosphere, both in polar and in temperate latitudes. The results of initial experiments have suggested that major factors have been omitted in the formulation of current theory of the lower ionosphere. As will be shown later, one of the main results of the work was the demonstration that the electrical properties of the lower ionosphere are strongly influenced by dynamical aspects of the circulation in the same heights. This finding applies to temperate latitudes, and the variation of the effect with latitude is currently under study. Again, in the polar regions the influence of corpuscular radiation, though variable over the sun-spot cycle, has been found to be at times more important than photon influx in determining electron densities. Both of these results suggest that further attempts should be made to give an adequate description of the phenomena of the lower ionosphere as a preliminary to more comprehensive theories.
