NEUTRAL EXOSPHERE. “In addition to the solar wind flow, the atmosphere contributes both to the neutral and charged particle density in the magnetosphere. The neutral exosphere, or the upward extension of the atmosphere, fills the near-Earth space with an exponentially decreasing density.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

CUSP OF CHANGE. “The use of written texts for scientific communications, as we know them, is relatively recent. In the tradition of the paper article a clear document structure emerged; a structure characterised by its linear build up and closed character. In an electronic environment, where all articles and parts thereof can be interconnected, new ways of presenting scientific information will develop. The electronic information transfer of the future will be, in essence, a transfer of well-defined, cognitive information modules.” https://lnkd.in/d4g67F9 View in LinkedIn

RING CURRENT COMPOSITION. “During magnetically active times, ion outflow from the ionosphere is greatly enhanced, and consequently the ring current composition changes from being dominated by solar wind protons and doubly charged helium to consisting large percentages (up to dominating the mass and energy density) of ionospheric oxygen and to lesser amounts of singly charged helium.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

“THE RING CURRENT encircling the Earth roughly in the region 2–7 RE from the Earth consists of plasmas originating both from the solar wind and the ionosphere. The ring current typically consists of ions in the energy range from a few tens of keV to several hundred keV, and has a highly variable intensity controlled by the level of geomagnetic activity.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

BETWEEN ELECTRIC FIELDS. “In the vicinity of this boundary, the plasma density has a sharp gradient; this is known as the plasmapause. Particles inside the trapping boundary remain on closed drift paths around the Earth while those outside the trapping boundary drift under the dawn-to-dusk electric field to the dayside boundary and are lost in the outer magnetosphere and eventually to the solar wind.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

COLLIDING ELECTRIC FIELDS. “The Earth’s rotation sets up an electric field, which drags the cold plasma into a corotational motion. The interplay between the solar wind-imposed electric field and the corotation electric field creates a boundary inside of which particles are trapped on closed orbits around the Earth.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
