significantly affect the ionosphere–thermosphere system. Chorus and ECH waves
cause diffuse aurora. ULF waves modulate chorus wave activities and produce
pulsating aurora, and the dissipation of ULF wave current systems can heat the
ionosphere. EMIC waves cause precipitation of relativistic electrons from the
radiation belt to the ionosphere and even down to the mesosphere. Such particle
precipitation ionizes the upper atmosphere, enhances the ionospheric
conductivity, and modifies the ionospheric electrodynamics. In turn, the
thermosphere responds to the ionospheric variation via Joule heating. Recent
spacecraft missions like THEMIS, RBSP, and MMS have unveiled the
characteristics and distribution of inner magnetospheric waves. Ground
observatories like SuperDARN, PFISR, and THEMIS have revealed the wave impacts
on the ionosphere. Therefore, it is timely to discuss the role of
magnetospheric waves in the magnetosphere–ionosphere coupling processes. This
session invites papers on observations, simulations, theoretical
investigations, or any combination of the three.</div><div class=""><br class=""></div><div class="">Convers:</div><div class="">Hyunju Connor, U of Alaska Fairbanks</div><div class="">Allison Jaynes, U of Iowa</div><div class="">Michael Hartinger, Virginia Tech</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Thank you very much,</div><div class="">Hyunju Connor.</div><div class=""><br class=""></div><div class=""><br class=""><div class="">
