Understanding Earth’s Ring Current: Measurements, Theory, and Modeling II Posters

Session ID#: 51167

Session Description:
Understanding the formation and the decay of Earth's ring-current is one of the most important topics in magnetospheric physics. It is known that Earth'€™s ring-current formation, mostly due to the ion dynamics, has a profound impact on Earth'€™s magnetic field and on the dynamics of trapped radiation.  As the ions are injected into, and drift, through the Earth's inner magnetosphere they interact with the intrinsic and induced electric and magnetic fields. Wave-particle interactions are then an important component of the ring current dynamics. Other processes, such as charge exchange, diffusion, etc., are also important in the lifetime of the ring-current, which effects are more important in different regions of the magnetosphere are still outstanding questions. This session seeks observational contributions using data from current missions such as Van Allen Probes, Arase (ERG), MMS, THEMIS, Cluster, etc., and new results on theory and modeling of ring current processes.
