Abstract
The intensity of solar soft x-rays (50...230A) as computed by Elwert is found to be sufficient to cause the ionization of the ionospheric layer. On the other hand, preionization of molecular oxygen by ultraviolet chromospheric radiation (A, Nicolet) could perhaps also be admitted, if it could be accepted that the dissociation of atmospheric oxygen occur in a high transition layer of considerable thickness (100-150 km). The first process is probably predominant.
