Paleo-upper range limit of tree elevation from the Last Glacial Maximum (LGM) to 1950 Common Era (CE)

Here, we presented a high-resolution (1 km) reconstruction of paleo changes in the upper range limits of trees across the Tibetan Plateau, at 100-year intervals since the Last Glacial Maximum (~22 kyr BP). This reconstruction was developed by integrating multi-satellite-derived high-resolution map, <i>in situ</i> dendrochronological observation and paleoclimate dataset into a novel climate-driven predictive model. Each row represents a specific location with its corresponding upper range limit of trees, while columns represent temporal intervals at 100-year resolution for past 22 ka. Grid cells marked as NaN indicate areas with no trees.
