Short summary

In general, it is not easy to examine unseasonable weather years that have affected human history using a single proxy. In this study, we propose a new method to quantitatively extract drought/long-rainfall events over the past 400 years by integrating tree-ring cellulose oxygen isotope ratios and historical documentary records. The results can be utilized to investigate the relationship between climate and long human history.
