This dataset represents global tree heights based on a fusion of spaceborne-lidar data (2005) from the Geoscience Laser Altimeter System (GLAS) and ancillary geospatial data. See [Simard et al. (2011)] (Mapping forest canopy height globally with spaceborne lidar - Simard - 2011 - Journal of Geophysical Research: Biogeosciences - Wiley Online Library) for details.
