Near-Earth Radiation Belt Physics and Active Experiments

Session ID#: 160241

Session Description:
This session is dedicated to the electromagnetic environment and the physical processes responsible for variations in the radiation belts in the near-Earth region (L<4.5), particularly those associated with precipitation into the atmosphere, whether they are caused naturally or by active experiments.  In the inner belt, long timescale processes lead to persistent radiation. Complexity arises from the dependence of the waves/processes on longitude and local-time and from the geomagnetic activities involving solar drivers and MLT variations. Conversely, in the slot region and the outer belt, loss associated with wave-particle interactions and causing atmospheric precipitation can be much faster and highly varying. Fast particle injections occur, competing with and obscuring the slower processes. This session solicits observational studies from satellite missions, active experiments, ground measurements, and numerical studies involving particles (electrons/ions/protons) dynamics, electromagnetic waves (existence, generation, properties, effects), wave-particle interactions, large-scale electric/magnetic fields, the plasmasphere, atmospheric precipitation, and effects in the ionosphere.
