CEDAR: Middle Atmosphere Studies Above Logan, Utah Using the Consortium Lidar Facility

研究人员将利用犹他州立大学的两台激光雷达研究中层大气的密度和温度结构。瑞利散射激光雷达将测量30至90公里高度的温度，而共振激光雷达将探测80至105公里高度的大气。现有的瑞利激光雷达将在即将到来的冬季进行维修并运行约100小时。目前正在开发的亚历山大石激光雷达将进行部署和测试。与同一位置的光学仪器的协调观测将允许研究中层大气的动力学，包括重力波、中性风和中间层逆温层

The investigators will study the density and temperature structure of the middle atmosphere using two lidars at Utah State University. A Rayleigh scatter lidar will measure temperatures in the altitude range from 30 to 90 km, while a resonance lidar will probe the atmosphere between 80 and 105 km altitude. The existing Rayleigh lidar will be repaired and operated for about 100 hours during the coming winter. The alexandrite lidar, currently being developed, will be deployed and tested. The coordinated observations with co-located optical instruments will allow studies of the dynamics of the middle atmosphere, including gravity waves, neutral winds, and mesospheric inversion layers.***
