From: Evaluating spatial coverage of data on the aboveground biomass in undisturbed forests in the Brazilian Amazon

Map Scale Spatial resolution Temporal scale (years) Field forest plots/source Study area plots/sampled area (ha) Remote sensing products/other inputs Model
Saatchi et al. [31] Amazon Basin 1 km 2000–2004 544/many sources ~ 361/~ 1633d MODIS (NDVI, LAI, % tree cover), JERS-1 radar, SRTM/vegetation map, climate data (WorldClim) Biomass classification approach

Saatchi et al. [18] Pantropical 1 km 2000 4079b (493 for calibration)/many sources ~ 707/~ 1770d MODIS (NDVI, LAI, % tree cover), LiDAR from GLAS/forest height map MaxEnt
Baccini et al. [33] Pantropical 500 m 2007–2008 283b/measured No data MODIS, LiDAR from GLAS, SRTM RandomForest

  1. RAINFOR Amazon forest inventory network, TEAM tropical ecology, assessment and monitoring, MODIS moderate resolution imaging spectroradiometer, NDVI normalized difference vegetation index, LAI leaf area index, GLAS geoscience laser altimeter system, LiDAR light detection and ranging, SRTM shuttle radar topography mission, JERS-1 Japanese earth resources satellite 1
  2. aAGB field measurements
  3. bWe did not have access to the locations of the plots
  4. cIn the case of the RadamBrasil plots, we had the locations of only 1682 plots
  5. dThe total area of the plots was estimated because the plot had different sizes
