Example subset of aboveground biomass density (AGBD; Mg ha-1) predictions from the GEDI Level-4A footprint product over Northern California, U.S., spanning April to July 2019. GEDI footprints are spaced 60m along-track and 600m across-track.

Body
GEDI L4A Version 2 predictions of aboveground biomass density and estimates of the prediction standard error within each sampled geolocated laser footprint now available.
