Abstract:

A brief outline of the theories capable of explaining the electric field observed at a great distance beyond the visibility is given. The conclusion that each theory is valid for a particular atmospheric model is arrived at. The results of measurements, made in France and abroad, which demonstrate the existence of layers characterized by abrupt variations of the index of refraction are given. These layers appear to exist permanently in all parts of the globe, but their characteristics vary with the meteorological situation. Author
