The purpose of this study is to perform a detailed analysis of unusually high nighttime electron temperature events (NETEs), which are regularly observed by the Millstone Hill radar. Studying these events will improve understanding of the nature of the particle and heat coupling between the ionosphere, plasmasphere, and conjugate ionosphere. Ultimately, this study will determine the cause of these events and their behavior, as well as lead to a better understanding of the nature of plasmapause processes. To accomplish this, detailed case studies will be performed on data already in the CEDAR data base. Also, new high quality data will be obtained at Millstone Hill, allowing the determination of particle and heat fluxes. Finally, this study should help to resolve the current discrepancy between modeled and measured ionospheric electron densities at night.

本研究的目的是执行一个详细的分析异常高夜间电子温度事件（NETEs），这是由磨石山雷达定期观测。研究这些事件将提高对电离层、等离子层和共轭电离层之间的粒子和热耦合性质的理解。最终，这项研究将确定这些事件及其行为的原因，以及更好地理解浆层ause过程的本质。为此，将对CEDAR数据库中已有的数据进行详细的案例研究。此外，将在磨石山获得新的高质量数据，从而可以确定颗粒和热通量。最后，这项研究应该有助于解决夜间电离层电子密度模型和测量值之间的电流差异。
