 ICSAT-2 is a satellite mission designed to measure the Earth's surface elevations with unprecedented accuracy. It is used to study a wide range of topics including climate change, sea level rise, and ocean circulation. In this paper, we demonstrate how ICSAT-2 data can be used to analyze the olean sand dunes, which are formed by wind erosion. We show that ICSAT-2 data provide higher resolution than traditional digital elevation models, DMs, such as those derived from the Shuttle Radar Topography mission, SRTM. This allows us to better understand the morphology of these dunes and their evolution over time. This article was authored by Kashbakt Raymond, Nadim Fareed, and Hon Jay Choo.
