Collaborative Research: CEDAR--A Long-term Investigation of Auroral and Tidal Forcing of E-region Thermospheric Winds at High Latitudes

该项目将使用扑克平面非相干散射雷达（PFISR）的8年数据集来研究高纬度低热层风的气候学和变异性。分析将讨论来自不同来源的能量和动量转移的相对贡献问题。将开发一个风廓线的长期数据库，并提供给社区，用于测试复杂的模型。这项研究将促进对磁层、热层和大气之间离子中性耦合和能量、质量和动量传递的理解，并将研究极光对低层热层风的影响。案例研究将用于研究强大气或强极光强迫事件。长期数据库将提供有关低层热层风趋势的信息，以及哪些强迫机制对长期变率负有最大责任。

This project will use an 8-year data set from the Poker Flat Incoherent Scatter Radar (PFISR) to investigate the climatology and variability of high-latitude lower thermospheric winds. The analysis will address questions of the relative contribution of energy and momentum transfer from different sources. A long-term database of wind profiles will be developed and made available to the community to be used for testing of complex models.This study will advance the understanding of ion-neutral coupling and energy, mass and momentum transfer between the magnetosphere, thermosphere, and atmosphere, and will investigate auroral effects on lower thermospheric winds. Case studies will be used to examine events of strong atmospheric or auroral forcing. The long-term data base will provide information about trends in lower thermospheric winds and which forcing mechanisms are most responsible for long-term variability.
