             abstract = "The tropical savanna in Brazil known as the Cerrado covers circa 
                         23% of the Brazilian territory, but only 3% of this area is 
                         protected. High rates of deforestation and degradation in the 
                         woodland and forest areas have made the Cerrado the second-largest 
                         source of carbon emissions in Brazil. However, data on these 
                         emissions are highly uncertain because of the spatial and temporal 
                         variability of the aboveground biomass (AGB) in this biome. 
                         Remote-sensing data combined with local vegetation inventories 
                         provide the means to quantify the AGB at large scales. Here, we 
                         quantify the spatial distribution of woody AGB in the Rio Vermelho 
                         watershed, located in the centre of the Cerrado, at a high spatial 
                         resolution of 30 metres, with a random forest (RF) 
                         machine-learning approach. We produced the first high-resolution 
                         map of the AGB for a region in the Brazilian Cerrado using a 
                         combination of vegetation inventory plots, airborne light 
                         detection and ranging (LiDAR) data, and multispectral and radar 
                         satellite images (Landsat 8 and ALOS-2/PALSAR-2). A combination of 
                         random forest (RF) models and jackknife analyses enabled us to 
                         select the best remote-sensing variables to quantify the AGB on a 
                         large scale. Overall, the relationship between the ground data 
                         from vegetation inventories and remote-sensing variables was 
                         strong (R2 = 0.89), with a root-mean-square error (RMSE) of 7.58 
                         Mg ha-1 and a bias of 0.43 Mg ha-1.",
