The airborne LiDAR data was used as a reference to improve the canopy height products derived from the spaceborne LiDAR systems GEDI and ICESat-2. In the dataset, the attribute "predicted" represents the improved canopy height.The data within the airborne LiDAR coverage have been validated and evaluated. However, for the other datasets, their broader spatial extent may be affected by the representativeness and spatial distribution of the samples.
