SM021:
Energetic Particle Precipitation: New Findings and Measurement Platforms





Session ID#: 23627

Session Description:
Precipitation into the atmosphere is an important loss process for energetic particles in Earth’s magnetosphere.   Quantification of such loss, as well as understanding of the physical mechanisms behind it through observation and simulation, is critical to our understanding of the dynamics of magnetospheres, magnetosphere-ionosphere interactions, and the chemistry and dynamics of the upper atmosphere.  Recent observations from a wide range of platforms, including balloons, ground observatories, and CubeSats, can provide important constraints on the spatial, temporal, and spectral characteristics of precipitation events.  This session welcomes submissions exploring energetic (~keV through >MeV) particle precipitation and the impact of this process on both trapped magnetospheric populations as well as atmospheric dynamics.  We especially encourage presentations utilizing different measurement types and platforms, as well as theory and modeling of the causes and effects of precipitation.
