CEDAR: A Complement of Optical Instruments for the Polar Cap Observatory: Continued Support

研究人员将在西北地区雷索雷特湾的早期极地帽观测站部署、维护和操作三个共同位置的高性能光学仪器，持续三个观测季节。他们将分析来自仪器的数据，系统地解决中间层和热层物理中的一些问题。这些仪器包括：具有多发射能力的新型法布里-珀罗干涉仪（FPI），用于测量多普勒风和温度；带有裸CCD探测器和可编程滤光轮的全天空相机系统；以及韩国海洋研究与开发研究所（KORDI）的光谱气辉温度成像仪（SATI），以提供OH和O2排放的旋转温度。ASC和SATI已经安装在现场。FPI在博尔德运行，并将于2003年7月部署在Resolute，取代原来的FPI，后者仅使用OH排放进行中性风测量。新的FPI也将能够测量557.7纳米和630纳米的辐射，提供多个高度的风和温度。具体的研究目标是研究重力和行星波特征、中层顶动力学和能量学、高纬地磁下热层动力学和能量学；高纬极光对结构和动力学的影响等离子体漂移、斑块和斑点；电离层-磁层耦合过程，包括焦耳加热。数据将提供给航空学界，研究人员将继续分配仪器的社区使用，以支持其他实验活动。FPI中的过滤轮位置可供其他研究人员使用。将通过观察和分析伙伴关系为其他研究人员提供支持。重要的国际伙伴关系是这项研究的一个关键因素。学生实地观察工作的教育机会一直是先前工作的一个重要方面，并将继续通过大学伙伴关系加以追求。

The investigators will deploy, maintain, and operate three co-located, high performance optical instruments at the Early Polar Cap Observatory at Resolute Bay in the Northwest Territories for three consecutive observing seasons. They will analyze the data from the instruments to systematically address a number of problems in mesospheric and thermospheric physics. The instruments are: A new Fabry-Perot interferometer (FPI) with multi-emission capability, for measurements of Doppler winds and temperatures; an all-sky camera (ASC) system with a bare CCD detector and programmable filter wheel; and a Spectral Airglow Temperature Imager (SATI) from the Korea Ocean Research and Development Institute (KORDI) to provide rotational temperatures from OH and O2 emissions. The ASC and SATI are already installed on site. The FPI is operational in Boulder and will be deployed at Resolute in July 2003, replacing the original FPI, which made neutral wind measurements using only the OH emission. The new FPI will be able to measure 557.7 and 630 nanometer emissions as well, providing winds and temperatures at multiple altitudes. Specific research objectives are investigation of gravity and planetary wave characteristics, mesopause dynamics and energetics, lower thermospheric dynamics and energetics at high geomagnetic latitude; impact of high-latitude auroras on structure and dynamics; plasma drifts, patches and blobs; and ionosphere-magnetosphere coupling processes, including Joule heating. Data will be made available to the aeronomy community and the investigators will continue allocating community use of the instruments to support other experimental campaigns. Filter wheel positions in the FPI are available for use by other investigators. Support for other researchers through observational and analysis partnerships will be pursued. A significant international partnership is a key element of the research. Educational opportunities for field observational work by students has been an important aspect of prior work and will continue to be pursued through university partnerships.
