CEDAR: Anomalous Nighttime Electron Temperature Events Over Millstone Hill: An Experimental and Theoretical Investigation

这项研究的目的是对米尔斯通山雷达定期观测到的异常高的夜间电子温度事件(NETE)进行详细分析。研究这些事件将有助于加深对电离层、等离子体层和共轭电离层之间的粒子和热耦合的本质的理解。最终，这项研究将确定这些事件的原因及其行为，并导致更好地理解等离子体停滞过程的本质。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，将在米尔斯通山获得新的高质量数据，从而能够确定粒子和热通量。最后，这项研究应该有助于解决夜间模拟的电离层电子密度和测量的电离层电子密度之间的电流差异。

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.
