This is a study to investigate the relationship between fine-scale neutral atmosphere structure, acoustic gravity waves, tides and the presence of sporadic sodium, iron and ion layers in the middle atmosphere. The study will make use of data obtained with radars and lidars during several observational campaigns over the last fifteen years. The observations will be compared to determine differences in the low and mid-latitude tidal and gravity wave processes and how they relate to layer formation. A parallel theoretical/numerical modeling effort will concentrate on formation of sporadic neutral and ion layers and on the breaking of acoustic gravity waves above the mesopause. The lidar data will be added to a centralized data base that will be accessible via the Mosaic networking system.

这是一项研究，调查细尺度中性大气结构，声重力波，潮汐和中间大气中零星钠，铁和离子层的存在之间的关系。 这项研究将利用过去15年来几次观测活动中雷达和激光雷达获得的数据。 将对观测结果进行比较，以确定低纬度和中纬度潮汐和重力波过程的差异以及它们与地层形成的关系。 一个平行的理论/数值模拟工作将集中在零星的中性和离子层的形成，并在中层顶以上的声重力波的破碎。 激光雷达数据将被添加到一个中央数据库，可通过Mosaic网络系统访问。
