Dynamics of the Inner Magnetosphere

Topic: Solar Physics

Session Title: Dynamics of the Inner Magnetosphere


The Earth’s inner magnetosphere is a complex environment that hosts multiple co-existing and coupled plasma populations, with energies ranging from sub-eV through to ultra-relativistic MeVs. Although each population has their own characteristic energies, composition, spatial distributions, and variations with geomagnetic activity, the populations are highly coupled with each other through a myriad of micro-scale wave-particle interactions and meso-scale plasma dynamics. Overall, the inter-dependency of the inner magnetospheric populations necessitates a cross-energy, system-level understanding of the inter-related dynamics.

In this session we will explore new research into the various plasma populations (including but not limited to, the inner and outer radiation belts, the ion and electron ring current populations, and cold plasmaspheric plasma), as well as the range of wave-particle interactions that couple them (e.g. ULF, chorus, EMIC waves, etc.). We will discuss how the system and its components respond to different types of geomagnetic activity, such as geomagnetic storms, substorms, injections, and solar wind structures. This will also include how the inner magnetosphere is coupled more broadly to the wider solar wind, magnetospheric, and ionospheric environments.

We welcome contributions spanning observational (ground and space), modelling, simulations, and theoretical research. We welcome new science that draws upon the wide suite of observational resources, such as the Van Allen Probes, MMS, Arase, Cluster, THEMIS, GPS, SuperDARN, SuperMAG, EISCAT, and VLF receivers, and many more. We invite both new science results, new mission and instrumentation concepts or developments, as well as review papers.
