HAZARDOUS ELECTRONS. “Relativistic electrons in the inner magnetosphere are a major hazard for Earth-orbiting spacecraft, and therefore prediction of the electron fluxes especially at geostationary orbit is one of the key targets for space weather applications.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

INNER PLASMA POPULATIONS. “The inner magnetosphere hosts multiple plasma populations: the hot ion ring current in the tens to hundreds of keV energy range, the outer van Allen belt electrons with energies from 100 keV up to several MeV, and the cold plasmaspheric plasma (from a few eV to few hundred eV) originating from the ionosphere. Recent research results have emphasized how effectively all these seemingly distinct populations and their dynamics are coupled together.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

INNER MAGNETOSPHERE. “The quasi-dipolar inner magnetosphere extending roughly out to geostationary distance has a variable field structure caused by the competing effects of the internal dipole field, magnetotail current sheet, dayside magnetopause currents, and the ring current within the region itself.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAGNETOSPHERE. “The structure and dynamics of the current sheet in the magnetotail control the energy storage and release processes initiated with the enhanced dayside reconnection at the magnetopause. The high-speed plasma flows, strong particle energization processes, and rapid reconfiguration all are major parts in creating the space weather effects in the inner magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

STORM DYNAMICS. “During storms, the plasmapause moves inward due to the enhanced solar wind driving, while a drainage plume develops in the dusk sector. Within this plume, the cold plasma flows outward toward the magnetopause thus escaping from the plasmasphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

DYNAMIC PLASMASPHERE. “During magnetic quiescence, the plasmasphere is expanded and the plasmapause can be located outside geostationary orbit. Particularly during low magnetic activity conditions, there is significant variability in the plasmapause location.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

GIANT GYRES. “Statistical studies have shown that the position of the plasmapause is correlated with geomagnetic activity, being at smaller radial distances during higher levels of activity. This can be understood by the enhanced convection electric field moving the boundary between the convection-dominated outer region and the co-rotation-dominated inner region closer to the Earth.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

PLASMAPAUSE. “The location of the outer boundary of the plasmasphere, the plasmapause, is controlled by the relative intensities of the solar wind-imposed electric field and the co-rotation electric field. Although roughly circular in shape, the plasmapause often shows an elongation in the duskside, following the general electric field pattern.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
