Electric fields produced by the thermospheric neutral wind dynamo and originating in the magnetosphere generate ion drifts that are sampled by polar orbiting Defense Meteorological Satellite Project (DMSP) satellites F15 and F13. These data, from the years 2001 and 2002 are assembled and analyzed at four distinct local times and used to determine the morphology of zonal ion drift as functions of latitude and magnetic activity. The research product is improved understanding of a variety of ion-transport phenomena, including traveling ionospheric disturbances (TIDs), storm-time enhancements of ion densities. In addition, the coupling of the magnetosphere to the ionosphere is intrinsically investigated by establishing the low latitude limit to the auroral electric field as well as its response to magnetic activity. The data mining, archiving, and correlative analysis is tasked to a female aeronomy graduate student.

由热层中性风发电机产生并源自磁层的电场产生离子漂移，极轨道国防气象卫星项目（DMSP）卫星F15和F13对其进行了采样。 这些数据，从2001年和2002年的组装和分析在四个不同的当地时间，并用于确定纬向离子漂移的形态作为纬度和磁活动的函数。 该研究成果提高了对各种离子传输现象的理解，包括电离层扰动（TID），离子密度的风暴时间增强。 此外，磁层到电离层的耦合本质上是通过建立极光电场的低纬度极限及其对磁活动的响应来研究的。 数据挖掘、归档和相关性分析的任务交给了一位女性高空气象学研究生。
