Description:
After solar eruptive processes, such as solar flares and/or coronal mass ejections, solar particles are accelerated to the high energy range. In most cases, the energy of accelerated solar particles reaches several hundred MeV, and sometimes reaches the GeV range. In the latter case, the energy is sufficient to induce a "shower" of atmospheric particles, the secondary particles of which reach the ground and are finally recorded by ground-based detectors, in particular neutron monitors. Such a class of extreme solar events is known as the GLE (ground-level enhancements) event class. Atmospheric ionization rates were calculated for GLE 71 (05/17/2012), GLE 72 (09/10/2017), and GLE 73 (10/28/2021)
