CEDAR: Sodium Lidar Study of Temperature and Wind Structures and Momentum Flux in the Midlatitude Mesopause Region

这项研究继续对科罗拉多州立大学使用双频窄带钠温度激光雷达获得的数据进行分析。激光雷达已经运行了三年，进行了147个夜晚的观测。这些数据将用于研究加热机制、潮汐效应、太阳周期和火山喷发的影响，以及中层顶的年度和半年度温度变化。这项研究将帮助建模人员微调他们的模型参数，并理解影响全球变化的中层顶区独特气候学背后的物理学。拟议的工作还包括继续进行定期观测，以确定大气温度的长期趋势，并调查潮汐和重力波扰动。这些数据将有助于检验对全球变暖的人为影响的模型预测，并有助于我们理解中层大气动力和辐射力之间的平衡。

This study continues the analysis of data obtained using the two-frequency, narrowband sodium temperature lidar at Colorado State University. The lidar has been operating for three years and 147 nights of observations have been made. The data will be used to study heating mechanisms, tidal effects, effects of solar cycle and volcanic eruption, and annual and semi-annual temperature variations in the mesopause. The study will help modelers fine-tune their model parameters and understand the physics behind the unique climatology in the mesopause region which impacts global change. The proposed effort also includes the continuation of regular observations to establish the long-term trends in atmospheric temperatures and to investigate tidal and gravity wave perturbations. These data will help to test model predictions of the anthropogenic effects on global warming and contribute to our understanding of the balance between dynamical and radiative forces in the middle atmosphere.
