Scatterplots of LiDAR vs field AGB estimates. a Sierra Nevada Mountains; b Barro Colorado Island; c Sierra do Mar. (1) Echo-basedmodel; (2) CHM-based model. Models were calibrated using the highest point density available at each study site. The effect of point density of the estimate was evaluated by applying the calibrated model to the thinned data. The solid line represents the 1:1 line
