SPA44C:
Energetic Particle Precipitation Mechanisms and Effects in the Magnetosphere-Ionosophere System II Posters

Submit an Abstract to this Session

Session ID#: 6349

Session Description:
Precipitation of particles into Earth's atmosphere can have profound effects on the ionosphere, atmosphere and magnetospheric systems. Wave-particle interactions and magnetic field topology changes can lead to precipitation of electrons and ions over a vast array of energies: from the eV-keV auroral energy range up to multi-MeV radiation belt energies. High latitude precipitation from very high-energy solar energetic particle events can penetrate Earth's magnetic structure easily and even has climatological implications. We invite contributions that explore the myriad of mechanisms causing particle precipitation and the outcomes of this precipitation on the M-I system. Studies involving recently-available space- and ground-based multipoint measurements are encouraged. Data sets of specific interest to this session include, but are not limited to, the Van Allen Probes, BARREL, the CARISMA array, and the THEMIS network. Likewise, new advances in theory and modeling of precipitation mechanisms are particularly welcome.
