Particles, Currents and Convection: Maps of the Magnetosphere as Viewed from the Ionosphere

该项目将利用从低地球轨道卫星，特别是DMSP卫星获得的数据，以及从SuperDARN雷达获得的电场数据，推断磁层的若干特征。其目标是创建等离子体状态、对流逆转位置和场定向电流结构的半球视图。通过利用同时从卫星和SuperDARN获得的数据，将有可能以面向边界的方式研究这些特征，以澄清它们之间的相互关系。给出了电子和离子在每个区域的平均能量和沉淀能通量的量化值。将为这些区域生成定量地图，新地图将分别对低纬边界层的开放和封闭部分进行编目。这些地图将包括等离子体边界、降水通量的性质、场向电流和对流反转边界。

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.
