Means with confidence intervals (black solid and dashed lines, respectively) and observed ecoregion-level (gray lines) performance metrics summarizing deviations between LTS-based and lidar-based AGB mapping for ecoregions within study regions at different aggregate-levels. a–c NRMSD = normalized root mean square deviation; d–f Pearson correlation coefficients; g, i intercept and j–l slope are simple linear regression parameters with lidar-based AGB as the response variable and LTS-based AGB as the predictor variable
