GEDI L4B: Global 1 km Gridded Aboveground Biomass Density Estimates

Global 1 km x 1 km gridded estimates of mean aboveground biomass density (AGBD) derived from NASA's GEDI satellite lidar mission. The data covers observations from mission week 19 (2019-04-18) to mission week 138 (2021-08-04), with each cell's mean AGBD statistically inferred from sampled footprints. Corresponding estimates of the standard error of the mean are also provided to quantify uncertainty from sampling and modeling.

Use Cases

• Modeling global carbon storage and sequestration based on gridded biomass density estimates.
• Analyzing vegetation change over time based on the 2019-2021 observation period.
• Assessing uncertainty in biomass measurements based on the provided standard error estimates.
• Calibrating or validating other biomass or land cover models based on the GEDI lidar sample data.

Strengths

• Provides a global spatial coverage at a 1 km resolution.
• Includes uncertainty quantification via standard error estimates for each grid cell.
• Data is produced by the National Aeronautics and Space Administration (NASA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific 2019-2021 observation window.
