The goal is to develop a phenomenological description of wind and temperature profiles of the mesosphere inversion layer and to supplement this with theoretical calculations. The lidar measurements provide temperature profiles in the middle atmosphere, from which researchers will deduce the density perturbations, potential energy, and spectra of atmospheric gravity waves. These results will be examined to determine whether monochromatic gravity waves of 10 to 15 km vertical wave lengths are essential to generate inversion layers through the coupling of these waves with the mesosphere tidal structure.

调查人员将分析来自新墨西哥州星火设施和马萨诸塞州米尔斯石山设施的瑞利激光雷达观测结果。 其目标是发展一个现象学的描述风和温度廓线的中层逆温层，并补充这与理论计算。 激光雷达测量提供了中层大气的温度分布，研究人员将从中推导出大气重力波的密度扰动、势能和光谱。 将对这些结果进行检查，以确定垂直波长为10至15公里的单色重力波是否是通过这些波与中层潮汐结构的耦合产生逆温层所必需的。
