Solar energetic particle (SEP) events, driven by solar flares and coronal mass ejections (CMEs), are occasionally accompanied by ground level enhancements (GLEs), detected by neutron monitors. While GLEs represent only a subset of SEP events, their occurrence may provide insight into the acceleratio...
