[HTML][HTML] Penetration of MeV electrons into the mesosphere accompanying pulsating aurorae
Pulsating aurorae (PsA) are caused by the intermittent precipitations of magnetospheric
electrons (energies of a few keV to a few tens of keV) through wave-particle interactions,
thereby depositing most of their energy at altitudes~ 100 km. However, the maximum energy
of precipitated electrons and its impacts on the atmosphere are unknown. Herein, we report
unique observations by the European Incoherent Scatter (EISCAT) radar showing electron
precipitations ranging from a few hundred keV to a few MeV during a PsA associated with a …
