Models of the Earth’s plasmapause position

正The plasmasphere is a region of relatively dense(~10–10000 cm~(–3))plasma,surrounding the Earth and extending to distances of about five Earth radii(R_E).It is filled with large amount of cold(~1 e V)plasma originated from the Earth’s ionosphere and co-rotating with the Earth due to the large scale co-rotation electric field.The outermost
