Fig. 1: GEDI footprint-level SSI across tropical forest regions.
From: Stand structure of tropical forests is strongly associated with primary productivity
a The explanatory power of individual principal components (PC1-4), explaining the variations of tree height (RH100, mean = 26.38, S.D. = 10.55), total plant area index (PAI, mean = 2.93, S.D. = 0.41), foliage height diversity (FHD, mean = 0.81, S.D. = 0.23), and total canopy cover (CC, mean = 81%, S.D. = 23%) of the GEDI data; the error bars represent one standard deviation. b The relative contributions of RH100, PAI, FHD and CC to the two axes of PC1 and PC2. c Frequency plots of stand structural indicator (SSI) values across all tropical regions. d Spatial distributions of GEDI footprint-level SSI across all tropical regions. The gray inserts show the frequencies of SSI distributions in the tropical regions of America, Africa and Asia, respectively.
