The purpose of this SGER project is to support collaborative research to be carried out utilizing the Clemson University relocatable optical observatory and the radar and optical instrumentation at Millstone Hill Observatory. The Clemson optical observatory is equipped with two optical instruments: a triple etalon Fabry-Perot interferometer (designated as SOFDI) and an all sky imaging photometer. The plan is to locate the optical observatory at a location near Newport, Vermont for four months of remote operations from March to July of 2003. The objectives of the proposed collaboration are listed as follows: 1) to obtain and compare simultaneous optical and radar measurements of meridional winds and temperatures during the daytime, 2) to obtain and compare simultaneous optical and radar observations of ion temperatures and ion drifts during twilight periods, 3) to carry out simultaneous bistatic observations of mesospheric and thermospheric winds and temperatures during the night to examine possible correlation between mesosphere and thermosphere gravity wave activity, 4) to search for possible evidence of the hot oxygen corona through the detection of an anomalous broadening of the 732 nm spectral profile and to compare these results with Millstone Hill results, 5) to search for possible evidence of the daytime formation of auroral discrete arcs, 6) to obtain and compare mesospheric wind measurements obtained with the U. of New Hampshire meteor wind radar with the results from the FPI measurements of mesospheric winds. This collaborative series of observations would serve as an excellent field test of the new design represented by the SOFDI FPI instrument before the planned deployment of the Clemson relocatable optical observatory to the location of Huancayo, Peru. Only an SGER award can support such a window of opportunity of fielding the SOFDI close to an ISR, namely that at Millstone Hill.

该SGER项目的目的是支持利用克莱姆森大学可重新定位的光学天文台和米尔斯通山天文台的雷达和光学仪器开展的合作研究。克莱姆森光学观测站配备了两台光学仪器：一台三标准具法布里-珀罗涉仪(指定为SOFDI)和一台全天成像光度计。该计划是将光学观测站设在佛蒙特州纽波特附近的一个地点，从2003年3月到7月进行为期4个月的远程操作。拟议合作的目标如下：1)获得和比较白天子午风和温度的同时光学和雷达测量，2)获得和比较黄昏期间离子温度和离子漂移的同时光学和雷达观测，3)在夜间同时对中间层和热层风和温度进行双站观测，以研究中间层和热层重力波活动之间的可能相关性，4)通过探测732 nm光谱轮廓的异常加宽来寻找热氧日冕的可能证据，并将这些结果与米尔斯通·希尔的结果进行比较。5)寻找白天形成极光离散弧的可能证据；6)获得美国新罕布夏州流星风雷达测量的中层风场，并将其与FP I中层风场测量结果进行比较。在计划将克莱姆森可重新定位光学观测站部署到秘鲁环卡约之前，这一系列合作观测将成为对SOFDI FPI仪器所代表的新设计的极好现场测试。只有SGER奖才能支持这样一个机会窗口，即将SOFDI部署在靠近ISR的地方，即米尔斯通山。
