ATM9979454absThe investigators will study the chemistry of meteoric metals in the mesosphere, the dynamics of the stratosphere and mesosphere, interaction of dynamics and chemistry in the mesosphere, meteoric input, and noctilucent clouds. The study will use observations made by two resonance lidar systems and one Rayleigh lidar located at Poker Flat, Alaska. The resonance lidar systems will make simultaneous common volume observations of two species in the mesopause region during each observation period (sodium and iron, or sodium and ionized calcium, or sodium and potassium). The lidar observations will be supplemented by measurements made with an OH interferometer, all-sky camera, photometer, magnetometer, and MF radar. The observational data will be used to develop chemical models and dynamical models of the mesopause region. The two sets of metal observations will force consistency in the chemical models while the Rayleigh lidar measurements will quantify the tidal and wave activity that propagates upward from the lower atmosphere. The measurements will also provide data for assessing the role of the next generation solid-state based wind/temperature lidar systems in the polar regions.

ATM9979454ABSTH研究者将研究中层，平流层和中层的动力学，中层，陨石仪，陨石输入和夜光云中的动力学，动力学和化学的相互作用。 该研究将使用两个共振激光雷达系统和位于阿拉斯加扑克平面的一个雷利激光雷达进行的观察结果。 在每个观察期间，共振激光龙系统将在间膜区域（钠和铁，钠和离子化的钙，钠和钾）中同时对两个物种进行共同体积观测。 LiDAR观察结果将通过OH干涉仪，全套相机，光度计，磁力计和MF雷达进行补充。 观察数据将用于开发中膜区域的化学模型和动力学模型。 两组金属观察结果将在化学模型中迫使一致性，而瑞利激光雷达的测量结果将量化从下层大气中向上传播的潮汐和波动活性。 该测量值还将提供评估极地区域中下一代固态风/温度激光痛系统的作用的数据。
