Excess radiation and ionization in the upper atmosphere
Abstract
A positive correlation is established between the intensity of the neutron component of cosmic rays during Forbush decreases and the deviation of F-region critical frequencies from median values Delta f0F2. The best results are obtained when values of the reflection frequency at fixed heights are used instead of Delta f0F2. A clear excess of the values at higher-latitude stations is observed in this case. It is assumed that electron-density variations in the F-region are due to excess-radiation and albedo fluxes of cosmic rays, which also have a positive correlation with the intensity of primary cosmic rays and the same latitudinal variation.
