ECHAM6-wiso和isoGSM2模拟输出的亚洲降水氧同位素时间序列数据集（1979-2017年）

利用嵌入同位素分馏过程的大气环流模式ECHAM6-wiso和isoGSM2模拟输出的降水同位素，对比研究了亚洲不同季风子系统和区域降水同位素的年际变化关系及其潜在的物理机制。研究结果表明在年际尺度上，东亚降水氧同位素与印度季风强度负相关而南亚降水氧同位素与西北太平洋季风指数正相关。其中，东亚研究区域范围为(105–115°E，25–35°N），印度研究区域范围为（75–80°E，13–20°N）。

This study uses precipitation isotope simulation outputs from two atmospheric general circulation models, ECHAM6-wiso and isoGSM2, which embed isotope fractionation processes, to conduct a comparative analysis of the interannual variability relationships of precipitation isotopes across different monsoon subsystems and regional areas in Asia, as well as their underlying physical mechanisms. The results demonstrate that on the interannual timescale, oxygen isotopes in precipitation over East Asia are negatively correlated with Indian monsoon intensity, while oxygen isotopes in precipitation over South Asia are positively correlated with the Northwest Pacific monsoon index. Specifically, the East Asian study region spans (105–115°E, 25–35°N), and the Indian study region covers (75–80°E, 13–20°N).
