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.

这个SGER项目的目的是支持利用克莱姆森大学可移动光学天文台和米尔斯石山天文台的雷达和光学仪器进行合作研究。 克莱姆森光学天文台配备了两个光学仪器：一个三标准具法布里-珀罗干涉仪（命名为SOFDI）和一个全天成像光度计。计划将光学观测台设在佛蒙特州纽波特附近的一个地点，从2003年3月至7月进行为期四个月的远程操作。拟议合作的目标如下：1）获得并比较白天对流层风和温度的同时光学和雷达测量，2）获得并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，第三章在夜间对中间层和热层的风和温度进行同时的双站观测，通过对732 nm光谱剖面异常展宽的探测，寻找热氧日冕的可能证据，并与Millstone Hill的结果进行比较;新罕布什尔州流星风雷达与FPI测量中层风的结果。 在按计划将克莱姆森可移动光学观测台部署到秘鲁的万卡约之前，这一系列合作观测将是对SOFDI FPI仪器所代表的新设计的一次极好的实地测试。 只有SGER奖才能支持在ISR附近部署SOFDI的机会窗口，即Millstone Hill。
