Multi-Source Spaceborne LiDAR Forest Canopy Height Retrieval by Integrating GEDI and ICESat-2
Forest canopy height is critical for quantifying terrestrial carbon stocks, assessing ecosystem productivity, and supporting biogeochemical modeling. Spaceborne LiDAR missions (e.g., GEDI and ICESat-2) enable forest canopy height mapping from regional to global scales, but they differ substantially in spatial coverage...
