Fig. 2From: Synergistic use of very high-frequency radar and discrete-return lidar for estimating biomass in temperate hardwood and mixed forestsPredicted versus observed biomass plot for best model with BioSAR variables (b40, mean NRCS response at backward 40°–45° angle bins (decibels)) and PALS variable (p 70, k al, 70th percentile of PALS height, all hits (meters), and kurtosis of PALS height, all hits). Solid and hollow triangles stand for the pine and hardwood stands, respectivelyBack to article page
