a Spatial distribution of the upper range limit of trees at 1 km2 resolution (left), and longitudinal/latitudinal distribution of treeline elevation and upper range limit of trees elevation (top/right). The solid lines represent the median values for each elevational category, calculated at 1 km intervals longitudinally. The curves have been smoothed using a Gaussian function, with the shaded regions indicating one standard deviation, and the background terrain obtained from ArcGIS basemap dataset. b The relationships between the multi-satellite-derived upper range limit of trees and visual interpretation from Google Earth images, with the 1:1 line (dashed) and the regression line (continuous). R2 and ME indicate the coefficient of determination and the mean error, respectively.
