CEDAR: The Longyearbyen Optical Station

朗伊尔城光学站是北半球唯一一个有定期航班服务的地面站，可以24小时观测极光和气辉光。EISCAT雷达极帽扩展部分将建在离观测站几英里的地方。该提案为朗伊尔城的维护寻求资金，以支持CEDAR和GEM项目，以便为持续的高纬度光学研究提供一个现成的地点。该站支持对昼侧和夜侧极光、电离层电流、热层和中间层的高纬度动态以及与臭氧循环有关的平流层次要成分的测量的研究。阿拉斯加大学与特罗姆瑟大学合作，将科考站发展成为北极苔原上的现代化研究设施，配备了一套一流的光学和磁性仪器，为游客提供了单独的观察舱，安装和维修区域，以及舒适的生活条件。pi计划继续这项工作，并对该站及其仪器进行中央支持的维护。

The Longyearbyen Optical Station is the only ground station in the northern hemisphere with regular scheduled airline service which permits 24 hour observation of the aurora and airglow. The EISCAT radar polar cap extension will be built a few miles from the observatory site. This proposal seeks funding for maintenance of Longyearbyen in support of the CEDAR and GEM programs so that it will provide a ready location for continued high latitude optical studies. The station has supported investigations of dayside and nightside aurora, ionospheric currents, high latitude dynamics of the thermosphere and mesosphere and also measurements of stratospheric minor constituents connected with the ozone cycle. In collaboration with the University of Tromso, the University of Alaska has developed the station to a modern research facility in the Arctic tundra complete with a set of first class optical and magnetic instruments, individual observing bays for visitors, areas for setup and repair, and comfortable living conditions. The PIs plan the continuation of this work with centrally supported maintenance of the station and its instrument complement.
