Collaborative Research: Thermospheric Neutral Wind Observation from the Antarctic Peninsula

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。该项目将在位于南极半岛的美国帕尔默站部署一台新的法布里-珀罗涉仪(FPI)。利用多重夜辉辐射(OH892 nm，87公里；O 557.7 nm，97公里；O630 nm，250公里；O2(0-1)865 nm，94公里)，FP I将观测中层和热层中性风和温度。该项目的团队将与在其南极站Mawson和Davis操作类似的FPI仪器的澳大利亚科学家合作，共同分析非洲大陆上空的中性风和温度数据分布，并解决下列科学问题：(1)热层中性风对韦德尔海异常的影响，(2)中间层和低热层的非迁移潮汐，(3)低热层经向风环流和中间层风切变，(4)高纬度地球磁场对中纬度热层的影响，(4)利用来自马萨诸塞州米尔斯通山的非相干散射雷达和热层观测对中间层和热层的共轭研究。与该项目相关的实地调查和分析工作非常适合研究生的参与和研究培训。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This project will deploy a new Fabry-Perot interferometer (FPI) at the U.S. Palmer Station located in the Antarctic Peninsula. The FPI will observe mesospheric and thermospheric neutral winds and temperatures using multiple nightglow emissions (OH, 892 nm, 87 km; O 557.7 nm, 97 km; O 630 nm, 250 km; and O2 (0-1) 865 nm, 94 km). The project's team will collaborate with Australian scientists who operate similar FPI instruments at their Antarctic stations Mawson and Davis to jointly analyze the neutral wind and temperature data distributions over the continent and address the following scientific problems: (1) Thermospheric neutral winds effects on the Weddell Sea Anomaly, (2) Non-migrating tides in the mesosphere and lower thermosphere, (3) Lower thermospheric meridional wind circulation and mesosphere wind shear, (4) High-latitude geomagnetic field effects on the mid-latitude thermosphere, and (4) Conjugacy studies of the mesosphere and thermosphere with the incoherent scatter radar and FPI observations from Millstone Hill, Massachusetts. The fieldwork and analysis efforts associated with this project are highly suitable for involvement and research training of graduate students.
