扩扩色勒冰川气温、降水的冰芯记录（1900-2011）

1）数据包含了1900-2011年以来年尺度的冰芯氧同位素和积累量记录，它们分别反映了研究区域的气温和降水变化；2）分析时，首先使用PICARRO测量冰芯样品 δ18O，并按照 δ18O的季节变化特征对冰芯定年；冰芯积累量根据冰芯密度、每年冰芯长度，并结合冰川流动模型计算生成；3）专业实验员和一线科研人员操作、维护仪器，确保分析数据可靠；4）该数据可用于分析青藏高原典型西风区一百余年来的气候环境变化规律，并能用于探讨这一时期的冰川演变，为预测将来冰川演变、水文水资源的变化及其对人类活动的影响提供科学参考。

First, this dataset includes annual-scale ice core oxygen isotope and accumulation records from 1900 to 2011, which respectively reflect the air temperature and precipitation changes in the study area. Second, during data analysis, the δ18O of ice core samples was first measured using a PICARRO instrument, and the ice core was dated based on the seasonal variation characteristics of δ18O; the ice core accumulation was calculated and generated based on ice core density, annual ice core length, combined with a glacier flow model. Third, professional experimentalists and frontline researchers operate and maintain the instruments to ensure the reliability of the analyzed data. Fourth, this dataset can be used to analyze the climate and environmental change patterns in the typical westerly region of the Qinghai-Tibet Plateau over the past century, as well as to explore glacier evolution during this period, providing scientific references for predicting future glacier evolution, changes in hydrology and water resources, and their impacts on human activities.
