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.

该项目将使用扑克平坦非相干散射雷达(PFISR)8年的数据集来调查高纬度低热层风的气候学和可变性。分析将解决不同来源的能量和动量转移的相对贡献问题。将开发一个长期的风廓线数据库，并提供给社区用于测试复杂的模式。这项研究将促进对离子-中性耦合以及磁层、热层和大气之间的能量、质量和动量转移的理解，并将调查极光对低热层风的影响。案例研究将用来研究强烈的大气或极光强迫事件。长期数据库将提供有关低热层风的趋势以及哪些强迫机制对长期变化负有最大责任的信息。
