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.

这项研究继续对科罗拉多州立大学的两种频率，窄带钠温度激光雷达获得的数据进行分析。 激光雷达已经进行了三年零147夜的观察。 这些数据将用于研究中层中的加热机制，太阳周期和火山喷发的影响以及年度和半年度温度变化。 这项研究将帮助建模者微调其模型参数，并了解影响全球变化的中间区域中独特气候背后的物理学。 拟议的努力还包括继续定期观察，以确定大气温度的长期趋势并研究潮汐和重力波扰动。 这些数据将有助于测试对人为影响全球变暖的影响的模型预测，并有助于我们理解中间气氛中动力学和辐射力之间的平衡。
