小白龙洞石笋氧同位素数据（距今53ka-36ka）

根据云南小白龙洞（24º12’N, 103º21’E, 海拔1500 m）编号为XBL-1的石笋获取了过去53-36ka的氧同位素的数据。该石笋长度约59cm，直径15-19cm。一共获取了747个数据，时间分辨率大约为2-93年，可用于反映5-10月的降水变化。

Oxygen isotope records covering the past 53–36 ka were acquired from stalagmite XBL-1 sampled from Xiaobailong Cave in Yunnan Province, located at 24°12′N, 103°21′E, with an elevation of 1500 m. This stalagmite measures approximately 59 cm in length and has a diameter ranging from 15 to 19 cm. A total of 747 data points were obtained, with a temporal resolution of roughly 2–93 years, which enables reconstruction of precipitation changes from May to October.
