The inner regions of planetary magnetospheres are characterized by dynamic electric and magnetic fields, a verity of plasma wave emissions, and populated by multiple plasma populations with diverse properties, occupying spatial regions that are partially or totally overlapping. The dynamics of these plasmas, fields, and waves arise from a combination of sources both external and internal to the magnetosphere. At Earth, the solar wind exerts a primary influence on the global dynamics of radiation belts, ring current, plasmasphere, and ionosphere. However, coupling among these plasmas via electromagnetic fields, currents, and wave-particle interactions provides a strong internal influence to inner magnetospheric dynamics. At outer planets such as Jupiter and Saturn that have much faster rotation and also have multiple moons serving as potential plasma sources, internal driving dominates global inner magnetospheric dynamics. Significant progress is being made, thanks to several current missions and theoretical studies (both analytical and numerical), but we have yet to fully quantify and understand the complex web of forces, fields, and waves that link the dynamics of various inner magnetospheric plasmas. We invite observational and theoretical contributions concentrating on properties of plasma populations, electric and magnetic fields, electrostatic and electromagnetic wave emissions, and their dynamical coupling processes in the inner magnetosphers of the Earth and outer planets. Contributions utilizing recent missions including Cluster, THEMIS, TWINS, and Cassini are especially welcome.
