  • [PS1-3-2-4-1] Spaceborne Laser Scanning
    Spaceborne Laser Scanning (SLS; e.g. Geoscience Laser Altimeter System - GLAS, Global Ecosystem Dynamics Investigation - GEDI) provides mainly global, depending on the platform (GEDI mounted on International Space Station (ISS) provides measurements over the Earth’s surface between 51.6° N and 51.6° S), measurements of the Earth's surface, with the potential on capturing additionally clouds and atmospheric aerosols. The spaceborne measurements allow to globally observe ice sheet and land elevations, approximate sea ice thickness, changes in elevation through time, vegetation coverage for biomass estimation, and height profiles of clouds and aerosols.
