Advances in Geodetic Mapping of Earth: Insights from NASA’s Satellite Laser Altimetry Missions (ICESat, ICESat-2, and GEDI) and the Path to EDGE

Session ID#: 252818

Session Description:
Satellite laser altimetry is critical for tracking Earth’s shifting dynamic systems. Since 2003, NASA’s satellite laser altimetry missions have transformed Earth observation through unparalleled precision and resolution in surface elevation retrieval over multiple targets. The Ice, Cloud and land Elevation Satellite (ICESat and ICESat-2) and Global Ecosystem Dynamics Investigation (GEDI) missions together offer global coverage, enabling monitoring of key vital signs of Earth. This interdisciplinary session brings together key mission findings: significant losses from ice sheets, glaciers, and sea ice; and the global distribution of terrestrial carbon stocks and fluxes, 3D vegetation structure, biodiversity and habitat, surface topography, global water reservoirs, sea level change, bathymetry, atmospheric dynamics, and aerosol transport. Earth Dynamics Geodetic Explorer (EDGE), in a Phase A Concept Study, ensures continuity of these vital records, using innovative swath mapping to enhance spatial and temporal sampling to capture driving processes.
