The GEDI team is continuing to expand the forest structure and biomass database with the goal of obtaining publicly available datasets that can be added to the MAAP. Some specific datasets on the horizon are:

• Brazil field data and lidar geotiffs in the Amazon (already in the GEDI database)
• ABoVE public field sites and airborne lidar in Alaska and Canada
• NEON field sites and airborne lidar across the USA
• GEDI field and airborne campaign data in Tennessee, Pacific Northwest, and Costa Rica

The GEDI team has developed and curated a global field and airborne lidar database to calibrate GEDI’s empirical aboveground biomass algorithms. The publicly-available portion of this database is available on the MAAP, and newly acquired public data will be continually updated. These data are useful for multi-mission biomass calibration and validation activities. So far, the MAAP hosts 25 field datasets and 24 curated coincident lidar datasets (Table 1), which span 4 continents (Figure 1). Through GEDI processing, these datasets have undergone QA/QC activities and have a standardized data and metadata format to promote ease of comparison across locations.
