Short summary
Spatial-energy distributions of the stationary fluxes of protons, helium ions, and ions of the carbon–nitrogen–oxygen (CNO) group in the Earth's radiation belts (ERBs) are considered here using data from satellites from 1961 to 2017. It is found that the results of these measurements line up, with some regular patterns present. Solar-cyclic (11-year) variations in the distributions of protons, helium ions, and CNO group ion fluxes in the ERB are presented.
