Ground elevation is provided as the mean elevation (in meters) of the center of the lowest waveform mode relative to the WGS84 reference ellipsoid. Canopy height is provided as the mean height (in meters) above ground of the received waveform signal that was the first reflection off the top of the canopy (RH100). These е…ѓ gridded products were derived from Level 2 (L2) geolocated laser footprint return profile metrics from the GEDI instrument onboard the International Space Station (ISS). This dataset provides Global Ecosystem Dynamics Investigation (GEDI) Level 3 (е…ѓ) gridded mean canopy height, mean ground elevation, and counts of laser footprints per 1 km x 1 km grid cells globally within -52 and 52 degrees latitude. The companion files must be downloaded separately from the data files. There are also seven companion files: the Algorithm Theoretical Basis Document (ATBD) for GEDI е…ѓ Gridded Land Surface Metrics, five image (.png) files corresponding to the gridded data files, and a. There are five data files associated with the е…ѓ product in GeoTIFF (.tif) format for the gridded canopy height and standard deviation, ground elevation and standard deviation, and laser footprint counts. Future versions will optimally interpolate data to produce the best estimate of the mean and its error for each grid cell. This first release of е…ѓ products are simple averages and standard deviations of the footprint profile metrics within each 1 sq. е…ѓ gridded products can be used to characterize important carbon and water cycling processes, biodiversity, habitat and can also be of immense value for climate modeling, forest management, snow and glacier monitoring, and the generation of digital elevation models. This dataset provides Global Ecosystem Dynamics Investigation (GEDI) Level 3 (е…ѓ) gridded mean canopy height, standard deviation of canopy height, mean ground elevation, standard deviation of ground elevation and counts of laser footprints per 1 km x 1 km grid cells globally within -52 and 52 degrees latitude.
