- Аннотация: Experiments on board low-Earth orbit satellites show that energetic electrons and protons (tens of keV) of the Earth's radiation belt can penetrate to the equatorial ionosphere. Impact of the energetic particles on the upper atmosphere and ionosphere was studied for the case of the geomagnetic storm on 22 July 2009. We have found that local ion concentration changed in regions of injections of the 30 keV electrons and protons into the low latitude ionosphere. We showed that increase of ion concentration in the F layer at dawn related with additional ionization of neutral gas by energetic electrons. Ionospheric irregularities at night can be caused by effect of energetic protons. We present the results of solar-cycle and annual variations of occurrence rate of electrons and protons injections into the ionosphere during the period from 1998 to 2019 years.
