Ozone and Auroral Spectra

IN 1941, we published a theory1 which provided, among other things, an explanation of seasonal and latitude variations in the thickness of atmospheric ozone. From this theory we were able to predict ozone thicknesses in latitudes for which, as yet, there are no direct observations-for example, in polar regions. Furthermore, we have shown that near the poles the ozone thickness should be practically zero soon after the winter solstice.
