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Clemson University可重新定位的光学天文台以及Millstone Hill天文台的雷达和光学仪器进行协作研究。 克莱姆森光学天文台配备了两种光学仪器：三重etalon fabry-perot干涉仪（指定为SOFDI）和一个所有天空成像光度计。该计划是在2003年3月至7月的佛蒙特州纽波特附近的一个远程操作中定位光学天文台。列出了拟议协作的目标如下：1）获得和比较同时的光学和雷达测量值白天的子午风和温度，2）在暮光期间获得和比较离子温度和离子漂移的同时光学和雷达观察结果，3）3）在夜晚进行中层和热层风和温度的同时进行双科学观察间球与热层重力波活性之间的可能相关性，4）通过检测732 nm光谱谱的异常扩展，以搜索热氧气电晕的可能证据极光离散弧的白天形成的可能证据，6）获得并比较了新罕布什尔州流星风雷达获得的中层风测量结果与中层风的FPI测量结果。 在计划在秘鲁华纳山（Huancayo）的位置的克莱姆森（Clemson）可重新定位光学天文台的部署之前，这一协作一系列观察结果将作为SOFDI FPI仪器所代表的新设计的出色现场测试。 只有SGER奖可以支持将Sofdi伸向ISR附近的Sofdi的机会之窗，即在Millstone Hill。
