The PIs will conduct a comprehensive study of the mesospheric metal layers in the Arctic. This will employ two field-proven laser systems to carry out simultaneous common volume observations of at least two species in each observation period. A resonance lidar already operating at Poker Flat will perform the daytime observations. The PI will extend current observations by installing a second lidar system to sound other mesospheric metal species against a continuous set of sodium observations. This will provide a set of comprehensive high-resolution, long-duration benchmark observations for studying a variety of aeronomy issues in the mesopause region. These observations will be supported by ongoing OH interferometer, all-sky camera, and photometer and magnetometer observations. In addition, collaborators at the University of Pennsylvania will analyze the results with time-resolved models.

研究所将对北极的中间层金属层进行全面研究。 这将采用两个经过实地验证的激光系统，在每个观测期内对至少两个物种同时进行共同体积观测。 已经在扑克平原运行的共振激光雷达将进行白天的观测。 PI将通过安装第二个激光雷达系统来扩展当前的观测，以根据连续的钠观测来探测其他中间层金属物质。 这将提供一套全面的高分辨率、长时间基准观测，用于研究中层顶区域的各种高层大气学问题。 这些观测将得到正在进行的OH干涉仪、全天空照相机、光度计和磁力计观测的支持。 此外，宾夕法尼亚大学的合作者将用时间分辨模型分析结果。
