Plasmaspause dynamics and plasmaspheric outflows

A three dimensional dynamic model of the plasmasphere coupled with the ionosphere model has been developed to determine the number density and temperatures of the different particles in the ionosphere, the plasmasphere, the plasmapause boundary layer and the plasmatrough. This is crucial because the plasmasphere plays a central role in magnetosphere-ionosphere dynamics and has also influence on the radiation belt populations. The position of the plasmapause, the limit of the plasmasphere, is highly dynamics with the geomagnetic activity. The model of the plasmasphere has been extended to give temperatures and composition and is provided as nowcasting and forecasting tool on the space weather portal.
