NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) released new Global Ecosystem Dynamics Investigation (GEDI) Level 4C data.
This dataset contains GEDI Level 4C (L4C) Version 2 predictions of the Waveform Structural Complexity Index (WSCI) and estimates of prediction intervals for each footprint estimate at 95% confidence. In this version, the granules are in sub-orbits. The algorithm setting group selection used for GEDI04_C is the same as in the GEDI02_A product. The footprints are located within the global latitude band observed by the International Space Station (ISS), nominally 51.6 degrees N and S and reported for the period 2019-04-17 to 2023-03-16. The data are provided in HDF5 format. On March 17, 2023, GEDI was temporarily moved to an alternate location on ISS, where it will remain offline for about 18 months. In 2024, GEDI returned to its original location and resumed operations on the station.
GEDI produces high-resolution laser ranging observations of the 3D structure of the Earth. GEDI’s precise measurements of forest canopy height, canopy vertical structure, and surface elevation greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. GEDI was funded as a NASA Earth Ventures Instrument (EVI) mission. It was launched to the ISS in December 2018 and completed initial orbit checkout in April 2019. Access data from the GEDI mission.
