This is a CAREER award to investigate observable effects of gravity waves in the mesosphere and lower thermosphere (MLT) region (∼80-100 km), while supporting and enhancing student research, teaching, and public outreach at Embry-Riddle Aeronautical University (ERAU). Gravity waves play a crucial role in defining the structure, dynamics, and variability of the MLT region by carrying and ultimately depositing momentum and energy between regions of the atmosphere. They are observed via their perturbations to chemical species and processes, by passive optical measurements of airglow, and active measurements by lidar and radar. Theoretical and modeling studies, inspired by both ground- and space-based observations, continue to expand our scientific understanding of gravity wave sources, processes, directionality and seasonality. The principal research objectives of this project are to model and quantify the evolution and observable effects of gravity waves in the MLT region, to improve the understanding and interpretation of wave processes measured by airglow instruments. Data from established sites will be used for studies of mountain waves over the Andes, and data from a new infrared airglow imager will be used for studies of convectively-generated gravity waves over Daytona Beach, Florida. The principal educational objectives of this project are to mentor and train students for careers as independent scientific researchers, and to inspire interest and enhance understanding of the atmospheric and space sciences among the general public. These teaching and outreach goals will be achieved through (1) undergraduate and graduate student research projects, (2) curriculum development for a new graduate-level course in computational methods for atmospheric dynamics, (3) construction of an educational website for the infrared imager, and (4) incorporation of a new upper-atmospheric outreach program into future ERAU Astronomy Open House events. The project will support and educate undergraduate and graduate student researchers, contribute to development of the new ERAU Engineering Physics Ph.D curriculum, enhance public awareness of atmospheric and space sciences through outreach, construct a website for the infrared airglow imager for general and scientific audiences, develop and refine a comprehensive generalized model for simulation of gravity waves and their observable effects, and disseminate results in refereed publications and conference presentations.

这是一个职业奖，调查重力波在中间层和低热层（MLT）区域（#8764;80-100公里）的可观察影响，同时支持和加强学生的研究，教学和安柏瑞德航空大学（ERAU）的公共宣传。 重力波通过携带并最终在大气区域之间沉积动量和能量，在确定MLT区域的结构、动力学和变化性方面发挥着至关重要的作用。它们通过对化学物质和过程的扰动，通过对气辉的被动光学测量以及激光雷达和雷达的主动测量来观察。受到地面和空间观测的启发，理论和建模研究继续扩大我们对重力波源，过程，方向性和季节性的科学理解。该项目的主要研究目标是模拟和量化MLT区域重力波的演变和可观察到的影响，以提高对气辉仪器测量的波过程的理解和解释。从已建立的站点获得的数据将用于研究安第斯山脉的山波，从新的红外气辉成像仪获得的数据将用于研究佛罗里达的代托纳海滩对流产生的重力波。 该项目的主要教育目标是指导和培训学生从事独立的科学研究工作，激发公众对大气和空间科学的兴趣并增进他们对这些科学的了解。这些教学和推广目标将通过以下方式实现：（1）本科生和研究生研究项目，（2）大气动力学计算方法新研究生课程的课程开发，（3）红外成像仪教育网站的建设，以及（4）将新的高层大气推广计划纳入未来ERAU天文学开放日活动。 该项目将支持和教育本科生和研究生研究人员，促进ERAU工程物理学博士新课程的开发，通过外联提高公众对大气和空间科学的认识，为一般和科学受众建立一个红外气辉成像仪网站，开发和完善一个模拟重力波及其可观测影响的综合通用模型，并在参考出版物和会议报告中传播成果。
