This is an Academic Research Infrastructure project to upgrade an existing lidar system at Utah State University (USU). It is a collaborative effort that includes investigators from USU, the University of Maryland, Clemson University, the University of Pittsburgh, and University College London. The lidar system provides measurements from which continuous profiles of atmospheric temperatures, densities and winds can be derived. The results will be used to study the transport of energy and momentum from the lower atmosphere to the mesosphere and lower thermosphere. The continuous observations over a long period of time will shed light on climatological questions relating to global change. The upgrade to the lidar system will increase the sensitivity of the instrument by about a factor of thirty. This is to be accomplished by constructing a telescope with a collecting area of 5 square meters. The project includes the construction of a building to house the lidar on the top of the Science and Engineering Building at USU. After the upgrade the lidar system will be one of the most powerful of its kind in the world. The data will be made available to atmospheric scientists and students.

这是一个学术研究基础设施项目，旨在升级犹他州立大学（USU）现有的激光雷达系统。 这是一项合作努力，包括来自USU，马里兰州大学，克莱姆森大学，匹兹堡大学和伦敦大学学院的调查员。 LiDAR系统提供了测量，可以得出大气温度，密度和风的连续曲线。 结果将用于研究能量和动量从下部大气到中层和较低热圈的运输。 在很长一段时间内的持续观察将阐明与全球变化有关的气候问题。 向LIDAR系统的升级将使仪器的灵敏度提高约三十倍。 这是通过建造一个望远镜的收集面积为5平方米来实现的。 该项目包括建造一座建筑物，以将LiDAR放置在USU科学和工程大楼顶部。 升级后，LIDAR系统将是世界上同类产品中最强大的一种。 数据将提供给大气科学家和学生。
