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

这笔赠款将维持和操作两个协调的“I类”光学仪器在极地帽观测站网站连续三个赛季，以及分析数据集从这些仪器系统地解决中间层和热层物理学的问题。 该仪器已经到位，是一个法布里-珀罗干涉仪和一个全数字化的全天空单色成像仪系统，带有热电冷却的裸CCD探测器和可编程滤光轮。 这两个仪器，部署在“早期PCO”的建设，完成了他们的第一个完整的赛季的观察，1996年5月，结果已经提交。 法布里-珀罗干涉仪的性能超出预期，其结果将继续通过CEDAR和加拿大赞助的努力与航空界分享。 此外，这两种仪器将为研究生Genene Fisher提供培训，调查：（1）重力波、“伪潮汐”和行星波特征;（2）高地磁纬度中层顶动力学和能量学;（3）高地磁纬度低热层动力学和能量学;（4）与其他高纬度仪器的合作研究;（5）高纬度极光对结构和动力学的影响，（6）等离子体漂移、斑块和斑点，（7）电离层-磁层耦合过程，（8）地磁扰动的影响。

This grant will maintain and operate two coordinated 'Class I' optical instruments at the Polar Cap Observatory site for three consecutive seasons, as well as analyze data sets from these instruments to systematically address problems in mesospheric and thermospheric physics. The instrument, already in place, are a Fabry-Perot interferometer and a fully digital all-sky monochromatic imager system with thermoelectrically cooled bare CCD detector and programmable filter wheel. The two instruments, deployed in the 'Early PCO' building, completed their first full season of observations in May, 1996, and results have been presented. The Fabry-Perot interferometer is performing above expectations, and results will continue to be shared with the aeronomical community through CEDAR and Canadian sponsored efforts. In addition, these two instruments will provide training for Genene Fisher, a graduate student, investigating: (1) gravity wave, 'pseudo-tides,' and planetary wave characteristics, (2) mesopause dynamics and energetics at high geomagnetic latitude, (3) lower thermospheric dynamics and energetics at high geomagnetic latitude, (4) collaborative studies with other high-latitude instruments, (5) impact of high-latitude auroras on structure and dynamics, (6) plasma drifts, patches and blobs, (7) ionosphere-magnetosphere coupling processes, and (8) effects of geomagnetic perturbations.
