CEDAR: Extended Analysis of Multi-Instrument Observational Data Sets from AIDA, ALOHA and Urbana, Illinois

本文研究了精细尺度中性大气结构、声波重力波、潮汐与大气中层零星钠、铁、离子层之间的关系。这项研究将利用雷达和激光雷达在过去15年的几次观测活动中获得的数据。将对观测结果进行比较，以确定低纬度和中纬度潮汐波和重力波过程的差异，以及它们与地层形成的关系。平行的理论/数值模拟工作将集中于零星中性层和离子层的形成以及中层顶上方声波重力波的破裂。激光雷达数据将被添加到一个中央数据库中，该数据库将通过Mosaic网络系统访问。

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.
