Preparation of Image Data from All Sky Camera for the Study of Gravity Waves in the Upper Atmosphere

Abstract

The tip of the Antarctic Peninsula, where King Sejong Station (KSS) is located, is known for extremely strong gravity wave activity. Since 2008, Korea Polar Research Institute has been operating All Sky Camera at KSS to investigate the gravity wave activity in the mesosphere and thermosphere regions. ASC system with three different filters can capture the 2-D structures of gravity wave in the upper atmosphere. However, the data analysis requires pre-processing of the image data from the ASC system. In this study, we present the processes of data preparation of the image data for obtaining physical parameters of the gravity wave in the upper atmosphere.
