Active remote sensing of 3D structure for ecosystem and surface-topography studies

Session ID#: 82549

Session Description:
Current and forthcoming satellite observations are producing measurements of land-surface topography and ecosystem structure at high spatial resolution and unprecedented accuracy. Multiple missions are now in operational or planning phases. These include NASA’s GEDI lidar, ICESat-2 and NISAR, ESA’s BIOMASS, and DLR’s Tandem-X and Tandem-L. Together these missions create new opportunities to map the three-dimensional structure of the global land surface, including surface elevation and deformation, canopy-height and leaf-area profiles, and aboveground biomass density and carbon stocks. This session addresses space-borne laser altimetry and radar measurement of land-surface topography and ecosystem structure. We encourage studies that address calibration and validation of mission data products, algorithm development, multi-sensor fusion, geodetic applications, and the integration of active remote sensing with passive optical sensors. Studies using airborne remote sensing in support of mission science are welcome. Initial results from GEDI and ICESat-2 will be presented.
