Causes and consequences of energetic particle losses in the coupled ionosphere-thermosphere-magnetosphere system

Session ID#: 77217

Session Description:
Particle losses act as one of the dominant processes contributing to the dynamic variations of energetic particles in the magnetosphere. These loss processes take place over a wide range of spatial scales from local wave-particle interactions to large system-scales, and on timescales from seconds to tens of days. With growing observations from space- and ground-based missions and development of sophisticated models, advances have been made on improved understanding of the context, causes, and consequences of magnetospheric particle losses. This session solicits presentations that feature recent progress made from ground-based and satellite observations and theoretical investigations to comprehend the losses of energetic particles and their effects on the ionosphere-thermosphere-magnetosphere coupled system. We encourage results utilizing measurements from Heliophysics System Observatory (e.g., Van Allen Probes, Arase, MMS, THEMIS, GOES) in conjunction with low-altitude and/or ground-based measurements (e.g., BARREL, POES, FIREBIRD, CubeSats, ground-based imagers, riometers and magnetometers) and coordinated modeling and theoretical efforts.
