This grant supports continued studies of the earth's ionosphere and plasmasphere. The proposed tasks for the next three years again concentrate on the subauroral and high latitude ionospheres and are a natural continuation and extension of past work. It is planned to expand the studies of the subauroral ionosphere with investigations into (1) the evolution of high altitude subauroral ion and electron heat flows during magnetic storms, (2) the aeronomical effects of observed soft electron and soft ion precipitation peaks, (3) processes responsible for ion and electron precipitation in this region, and (4) magnetospheric emissions triggered by ionospheric coupling. Planned studies of ion outflows, encompassing both high- and mid-latitude regions, include: (1) physical processes responsible for He+-dominated ion outflows, and (2) mid-latitude heavy ion upwelling events.

这笔赠款支持对地球电离层和等离子体层的继续研究。今后三年的拟议任务再次集中在亚极光和高纬度电离层，是过去工作的自然延续和延伸。计划扩大对亚极光电离层的研究，研究(1)磁暴期间高海拔亚极光离子和电子热流的演变，(2)观测到的软电子和软离子降水峰的大气效应，(3)该地区离子和电子降水的过程，以及(4)电离层耦合触发的磁层发射。计划中的离子外流研究，包括高纬度和中纬度地区，包括：(1)以He+为主的离子外流的物理过程，以及(2)中纬度重离子上行事件。
