东亚季风区中国祁连山地区树轮宽度数据

本数据集由东亚季风区中国祁连山地区树木年轮宽度数据组成。祁连山地区树轮包括52棵树芯，树种为祁连圆柏，测定的宽度数据为17081个，测量精度为0.01mm。树轮的宽度测量使用LINTAB 6树木年轮分析仪测量，并使用COFFCHA程序对交叉定年进行检验，以保证对所有树芯样本的量测和定年都准确无误。实验分析在中国科学院地质与地球物理研究所土壤结构与矿物实验室完成。该数据对对东亚季风边缘区的古气候方面的研究具有一定的意义。

This dataset comprises tree-ring width data collected from the Qilian Mountains area in the East Asian monsoon region of China. The tree-ring samples include 52 tree cores, with the tree species being Qilian juniper (Sabina przewalskii). A total of 17,081 width measurement records were obtained, with a measurement precision of 0.01 mm. The tree-ring width measurements were conducted using a LINTAB 6 tree-ring analyzer, and cross-dating was verified using the COFFCHA program to ensure the accuracy of all tree core measurements and dating procedures. Laboratory analyses were completed in the Laboratory of Soil Structure and Minerals, Institute of Geology and Geophysics, Chinese Academy of Sciences. This dataset has certain scientific significance for paleoclimate research in the marginal zone of the East Asian monsoon.
