Increased amplitude of the North Pacific Gyre Oscillation (NPGO) towards recent: evidence from tree-ring based reconstruction since 1596

This dataset provides a reconstruction of the NPGO from 1596 onwards from nineteen NPGO sensitive tree-ring chronologies in Himalayan Mountains, Rocky Mountains, Coastal Mountains and Alaskan Mountain Range. This dataset is discussed in a manuscript titled "Increased amplitude of the North Pacific Gyre Oscillation (NPGO) towards recent: evidence from tree-ring based reconstruction since 1596" by "Zhipeng Dong, Feifei Zhou, Zhuangpeng Zheng, Keyan Fang" which is submitted to Journal of Geophysical Research: Atmospheres.
