This dataset contains Global Ecosystem Dynamics Investigation (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 GEDI instrument consists of three lasers producing a total of eight beam ground
transects, which instantaneously sample eight ~25 m footprints spaced approximately every 60 m along-track. The
GEDI beam transects are spaced approximately 600 m apart on the Earth's surface in the cross-track direction, for an
across-track width of ~4.2 km. Footprint WSCI was derived from XGBoost regression models relating simulated
GEDI Level 2A (L2A) waveform relative height (RH) metrics to a 3D structural complexity metric calculated from
matched Airborne laser Scanning (ALS) point clouds. Four global WSCI models were trained on a plant functional
type (PFT) basis (i.e., deciduous broadleaf trees, evergreen broadleaf trees, evergreen needleleaf trees, and the
combination of grasslands, shrubs, and woodlands). For each of the eight beams, additional data are reported with
the WSCI estimates, including the associated uncertainty metrics, quality flags, and other information about the
GEDI L2A waveform for this selected algorithm setting group. Additional model outputs include WSCI predictions
for each of the six GEDI L2A algorithm setting groups and associated prediction intervals. Providing these ancillary
data products will allow users to evaluate and select alternative algorithm setting groups. The data are provided in HDF5 format.
