| 内容記述 | Vertical profiles of electron density obtained in the vicinity of the plasmapause using the Alouette-2 topside sounder have been analyzed to assess the presence of H(+) flow in the topside ionosphere. The observations in the midnight sector show clearly the presence of the plasmapause - i.e., there is a sharp boundary separating the poleward regions of polar wind H(+) flow and the more gentle conditions of the plasmasphere where light ions are present in abundance. In contrast, in the sunlit morning sector upward H(+) flow is deduced to be present to invariant latitudes as low as 48 deg (L = 2.2) in the regions normally known to be well inside the plasmasphere. The upward H(+) flux is so large 300,000,00 ions per sq cm per sec that the plasmapause cannot be seen in the latitudinal electron density contours of the topside ionosphere. |
