Atmospheric Gravity Wave Events Over Antarctica, America Wrobel May 2018

Atmospheric Gravity Wave Events Over Antarctica, America Wrobel

Physics Capstone Projects

This study used infrared (IR) image data obtained from McMurdo Station, Antarctica to investigate the properties of atmospheric gravity waves as they propagate into the upper mesosphere over Antarctica. The data were obtained as part of the international Antarctic Gravity Wave Instrument Network (ANGWIN). ANGWIN utilizes image data from several sites around Antarctica to investigate continent-wide propagation. This paper covers a study that reduced and analyzed two years of data from one particular site: McMurdo Station. An all-sky IR camera placed at McMurdo Station, Antarctica (77°83’ S, 166°61’ E) took one picture every ten seconds for the months of April …

Gravity Waves Over Antarctica, Vanessa Chambers

Physics Capstone Projects

As part of the international Antarctic Gravity Wave Instrument Network (ANGWIN) program, the Utah State University all sky IR imager has been operated at the British Antarctic Survey (BAS) Halley Station (75°36′ S, 26°12′ W) since 2012, obtaining valuable gravity wave information in the upper mesosphere and lower thermosphere region (~80 to 100 km). In this study, we have utilized a new 3D spectral analysis technique (Matsuda, et al., 2014) to quantify the horizontal phase velocity distributions of gravity waves over Antarctica. This new tool enables us to analyze extensive amounts of airglow imaging data in a relatively short time …
