A new GEDI-FIA fusion product was released in April 2025!  This dataset includes interpolated cumulative waveforms, with uncertainties, over national forest inventory (FIA) field plots (Burrill et al., 2024) across the contiguous United States. The predicted waveforms are for the Global Ecosystem Dynamics Investigation (GEDI) instrument, which produces high resolution laser ranging observations of the 3D structure of the Earth (Dubayah et al., 2020). GEDI’s data provides precise measurements of forest canopy height, canopy vertical structure, and surface elevation. This dataset also provides R scripts to extract information from user-selected plots and for training linear regression models between GEDI lidar metrics and target forest attributes. This dataset was produced using the methods in May et al. (2024).
