SA009:
Generation and effects of suprathermal particles in auroral and subauroral geospace





Session ID#: 24029

Session Description:
Suprathermal particles, ~tens of eV and greater, are ubiquitous in the auroral and subauroral geospace particularly during active periods. The objective of this workshop is to make an assessment of a wide range of nonlinear plasma processes that create suprathermal electrons and ions at subauroral and auroral latitudes and their effects in the ionosphere and magnetosphere. Possible topics of discussion will include (but are not limited to): What is the role of suprathermal electrons in the energy/momentum transfer between the hemispheres in the quiet time and magnetosphere-ionosphere in the disturbed time? How significant are suprathermal electrons in ion outflow events and heating of ionospheric plasma? What are key generation mechanisms of suprathermal particles in the magnetosphere and ionosphere? Invited/solicited speakers will summarize recent progress in satellite and radar observations and theory/modeling and discuss future directions of research to advance understanding of the role of suprathermal particles in the MI system.
