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.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目将在位于南极半岛的美国帕尔默站部署一个新的法布里-珀罗干涉仪（FPI）。FPI将使用多个夜光发射（OH，892 nm，87公里; O 557.7 nm，97公里; O 630 nm，250公里; O2（0-1）865 nm，94公里）观测中间层和热层中性风和温度。该项目的团队将与澳大利亚科学家合作，他们在南极站莫森和戴维斯操作类似的FPI仪器，共同分析大陆上的中性风和温度数据分布，并解决以下科学问题：（1）热层中性风对威德尔海异常的影响;（2）中层和低热层的非迁移潮汐，（3）低热层纬向风环流和中间层风切变，（4）高纬地磁场对中纬热层的影响，（4）用非相干散射雷达和马萨诸塞州Millstone Hill的FPI观测对中间层和热层的共轭研究。与本项目相关的实地考察和分析工作非常适合研究生的参与和研究培训。
