Monitoring Coastal Waves with ICESat-2
Journal of Marine Science and Engineering, 2023 The coastal zone faces an ever-growing risk associated with climate-driven change, including sea level rise and increased frequency of extreme natural hazards. Often the location and dynamism of coastal regions makes them a formidable environment to adequately study with in-situ methods.

ICESAT-2 ALTIMETRY AS GEODETIC CONTROL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Abstract. Digital elevation models (DEMs) are of fundamental importance for a large variety of scientific and commercial applications. Many geoscience studies require the most precise and current information about the Earth’s topography. Independent quality assessments of these DEMs are crucial to their appropriate use in land process studies, as ...

ICESat-2 Applications for Investigating Emerging Volcanoes [PDF]
Geosciences, 2022 Submarine volcanism in shallow waters (<100 m), particularly in remote settings, is difficult to monitor quantitatively and, in the rare formation of islands, it is challenging to understand the rapid-paced erosion. However, these newly erupted volcanic islands become observable to airborne and/or satellite remote sensing instruments.

ICESat-2 for Fluvial Geomorphology
, 2022 ICESat-2, a space-borne altimeter launched by NASA in 2018, has the ability to resolve the ground at sub-meter resolution. Using novel filtering techniques and data I/O, we are able to visualize bare-ground transects of heavily vegetated terrain. This presentation was given during the 2022 ESIP January meeting held virtually in January 2022.

Leaf area index retrieval with ICESat-2 photon counting LiDAR
International Journal of Applied Earth Observations and Geoinformation, 2021 This is the first study to inverse leaf area index (LAI) with photon counting LiDAR (i.e., Ice, Cloud, and Land Elevation Satellite-2/Advanced Topographic Laser Altimeter System, ICESat-2/ATLAS). A new framework composed of three major steps was applied:

Estimating Terrain Slope from ICESat-2 Data in Forest Environments
Remote Sensing, 2020 The global digital elevation measurement (DEM) products such as SRTM DEM and GDEM have been widely used for terrain slope retrieval in forests. However, the slope estimation accuracy is generally limited due to the DEMs’ low vertical accuracy over ...
