This project will utilize data obtained from Low Earth Orbiting (LEO) satellites, in particular the DMSP satellites, as well as electric field data obtained from the SuperDARN radars to infer a number of features of the magnetosphere. The goal is to create hemispheric views of plasma regimes, the location of convection reversals and field aligned current structures. By utilizing data obtained simultaneously from satellites and SuperDARN it will be possible to study these features in a boundary-oriented fashion that will clarify their interrelationship. Quantitative values of the average energy and precipitating energy flux will be given for each region for both electrons and ions. Quantitative maps will be generated for the regions and the new maps will separately catalog the open and closed portions of the Low Latitude Boundary Layer (LLBL). The maps will include the plasma boundaries, the nature of the precipitating fluxes, the field aligned currents and the convection reversal boundaries.

该项目将利用从近地轨道 (LEO) 卫星（特别是 DMSP 卫星）获得的数据以及从 SuperDARN 雷达获得的电场数据来推断磁层的许多特征。 目标是创建等离子体状态、对流反转位置和场对齐电流结构的半球视图。 通过利用从卫星和 SuperDARN 同时获得的数据，将有可能以面向边界的方式研究这些特征，从而阐明它们的相互关系。 将给出每个区域的电子和离子的平均能量和沉淀能量通量的定量值。 将为这些区域生成定量地图，新地图将分别对低纬度边界层（LLBL）的开放和封闭部分进行分类。 这些图将包括等离子体边界、沉淀通量的性质、场对准电流和对流反转边界。
