Hodographic Analysis Of Na Lidar Data To Measure Atmospheric Gravity Wave Parameters, Jeffrey Ormsby
Hodographic Analysis Of Na Lidar Data To Measure Atmospheric Gravity Wave Parameters, Jeffrey Ormsby
Physics Capstone Projects
The Utah State University Sodium lidar observatory, hosted in Science and Engineering Research building at Logan campus, measures the winds and temperature near the boundary of eddy diffusion dominated upper atmosphere between 80 and 110-km, where various atmospheric internal waves, especially atmospheric gravity waves (buoyancy waves), play important roles in the dynamics and chemistry. In this study, using a hodographic algorithm, the lidar data were analyzed to extract critical parameters of these gravity waves detected in this region, such as horizontal propagating phase velocity and wavelength. Results were compared with the independent Advanced Atmospheric Temperature Mapper (AMTM) observations, co-located at …

Physics Capstone Projects
In 1990 Dr. Chiao-Yao She developed a narrowband Na Temperature lidar in Colorado State University (CSU), it immediately became an important instrument to measure the temperature in mesopause region (80-105 km in altitude): the atmospheric layer between mesosphere and thermosphere [Krueger et al., 2015]. Led by Dr. Tao Yuan, this system was relocated to Utah State University (USU) in summer 2010 and has been continuing its exploration of upper atmosphere. This report will give a brief introduction to the theory and application of Sodium Lidar.
