Title : Wave-particle interactions in Earth's Radiation Belts
Abstract:
Earth's outer electron radiation belt is subject to great variability on a wide
range of timescales. Wave-particle interactions comprise a main controlling
influence on radiation belt dynamics. Acceleration and loss mechanisms of
radiation belt electrons include cyclotron resonant interactions with various
types of plasma wave including VLF chorus, ELF hiss, and EMIC waves. In this
introductory talk,we outline how timescales for the acceleration and loss of
radiation belt electrons due to these wave modes can be estimated.
