The first study of tree-ring stable carbon isotopes in Thailand has demonstrated that stable carbon isotope in northwestern Thailand represents a promising proxy for the temperature reconstruction of core-monsoon periods. A tree-ring δ 13 C chronology was constructed based on four cores covering the period of 1788-2013. After removing the long-term decreasing trend reflecting atmospheric CO 2 concentrations, the ∆ 13 C chronology was able to capture both temperature and hydro-climate signals. ∆ 13 C chronology showed particularly strong and significant negative correlation (r = -0.62, p
