“…As the source area of many large Asian rivers, the TP is covered by widespread coniferous forests, which has great potential for dendrochronology research (Peng et al ., 2019; Duan et al ., 2020). During the past decade, some researchers have established many climate‐sensitive tree‐ring chronologies in the river basins of the TP, which have revealed distinct or extensive historical environmental changes (e.g., He et al ., 2012; Lv and Zhang, 2013; Wang et al ., 2014b; Yang et al ., 2014; Gou et al ., 2015; Hochreuther et al ., 2015; Jiang et al ., 2017; Sun et al ., 2018; Chen et al ., 2018; Huang et al ., 2019; Chen et al ., 2019b; 2020). However, there is still a lack of instrumental precipitation data in many river source areas of the TP, and more tree‐ring chronologies are needed to interpret the past hydroclimate variability.…”
