This is a CAREER award that will set a solid foundation for a young scientist in developing a successful academic career through creative and exciting research, education, and integrated activities. The focus of the work plan is to advance research and education in lidar remote sensing and the applications of global lidar data to middle and upper atmospheric science. The research represents the first time that worldwide lidar data will be combined to create a global picture of the thermal structure of the mesosphere and lower thermosphere (MLT) via the use of satellite data and computer simulations. These efforts will significantly advance our understanding of the global MLT thermal structure and will further our knowledge of middle atmosphere dynamics that govern these variations. This research will also test and improve sophisticated global circulation models through use of these observational data. Because this project will identify altitudes in the MLT region where the temperatures undergo minimum seasonal variations, it will be important for establishing a temperature baseline that can be used to monitor climate change. This project will significantly advance our knowledge of the least understood region of the atmosphere, which is the equatorial and transition region of the middle atmosphere. This project will also significantly increase the usage of the lidar data collected at Arecibo Observatory, a national facility for scientific research, and at other sites around the world. Through analyzing past and present data, the large data backlog will be reduced, and scientific results will be obtained to help guide future data collection and instrumentation upgrades. The study will act as a bridge to encourage collaborations between modelers and experimentalists to dramatically increase the use of lidar data in testing and improving GCM models. This project provides excellent opportunities to educate and train graduate and undergraduate students, and to advance the integration of atmospheric science with lidar engineering. Students will gain extensive knowledge and experience through classroom learning of lidar remote sensing and then applying them to active lidar research. This project will help the principal investigator to successfully develop her academic career. The activities align well with the PI's career goals of establishing a strong lidar and atmospheric research and education group at the University of Colorado, and developing a center of excellence for lidar technologies and applications for the middle and upper atmosphere community.

这是一个职业奖，将通过创造性和激动人心的研究，教育和综合活动为成功发展学术职业的年轻科学家奠定坚实的基础。 工作计划的重点是推进激光雷达遥感的研究和教育，以及全球LIDAR数据在中大气科学上的应用。 这项研究代表了首次将全球激光雷达数据组合在一起，以通过使用卫星数据和计算机模拟来创建中层和下热层（MLT）的热结构的全局图片。 这些努力将大大提高我们对全球MLT热结构的理解，并将进一步了解我们对控制这些变化的中间气氛动态的了解。 这项研究还将通过使用这些观察数据来测试和改善复杂的全球循环模型。 因为该项目将在MLT地区确定温度最小的季节性变化的高度，因此对于建立可用于监测气候变化的温度基线非常重要。 该项目将大大提高我们对大气中最知名的地区的了解，这是中间大气的赤道和过渡区域。 该项目还将大大增加在Arecibo天文台收集的LiDAR数据的使用情况，这是一家国家科学研究设施以及世界其他地区的其他地点。 通过分析过去和现在的数据，将减少大数据积压，并获得科学结果，以帮助指导未来的数据收集和仪器升级。 这项研究将充当鼓励建模者与实验者之间的合作的桥梁，以显着增加激光数据在测试和改进GCM模型中的使用。 该项目为教育和培训毕业生和本科生提供了绝佳的机会，并推进了大气科学与LiDAR Engineering的整合。 学生将通过对LiDAR遥感的课堂学习获得丰富的知识和经验，然后将其应用于活跃的LiDAR研究中。 该项目将帮助主要研究人员成功发展她的学术生涯。 这些活动与PI的职业目标非常吻合，即在科罗拉多大学建立强大的激光和大气研究和教育小组，并为中层和高层氛围社区开发了激光雷达技术和应用的卓越中心。
