SGER: Daytime Optical and Radar Measurements at Millstone Hill Observatory

该SGER项目的目的是支持利用克莱姆森大学可搬迁光学天文台和Millstone Hill天文台的雷达和光学仪器进行的合作研究。克莱姆森光学天文台配备了两种光学仪器：三标准子法布里-珀罗干涉仪（称为SOFDI）和全天空成像光度计。该计划是在2003年3月至7月期间，将光学观测站定位在佛蒙特州纽波特附近，进行为期4个月的远程操作。拟议合作的目标如下：1)获取和比较白天经向风和温度的同时光学和雷达观测数据；2)获取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数据；3)在夜间同时进行中间层和热层风和温度的双基地观测，以检验中间层和热层重力波活动之间可能存在的相关性。4)通过探测到732 nm光谱剖面的异常扩展来寻找热氧日冕的可能证据，并将这些结果与Millstone Hill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)获取并比较美国新罕布什尔流星风雷达获得的中间层风测量结果与FPI测量的中间层风的结果。在计划将克莱姆森可搬迁光学天文台部署到秘鲁万卡约之前，这一系列合作观测将作为SOFDI FPI仪器所代表的新设计的出色现场测试。只有SGER合同才能支持在靠近ISR（即Millstone Hill）的地方部署SOFDI的机会。

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.
