Abstract:

The paper summarizes and discusses the known facts about aurorae occurring in the upper part of the ionosphere. It is concluded that it is difficult to deduce any precise quantitative information about the upper atmosphere from theAVAILABLE OBSERVATIONAL DATA, BUT THAT THESE DATA ARE NOT IN DISAGREEMENT WITH ROCKET AND SATELLITE RESULTS. Some estimates are made of the rates of ionization in the F-region of the ionosphere due to aurorae, and of the density in the beam of primary particles. It is suggested that monochromatic observations of very high auroral rays may give information on drifts and turbulence in the F-region. Author
