东亚季风区中国神农架地区树轮宽度数据

本数据集由东亚季风区中国神农架地区树木年轮宽度数据组成。神农架地区树轮包括128棵树芯，树种为巴山冷杉，测定的宽度数据为18936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 Shennongjia area within the East Asian monsoon region of China. The tree-ring samples from Shennongjia include 128 tree cores, with the tree species being Abies fargesii (Bashan fir). A total of 18,936 width measurements were obtained, with a measurement precision of 0.01 mm. Tree-ring width measurements were conducted using a LINTAB 6 tree-ring analyzer, and cross-dating validation was performed using the COFFCHA program to ensure the accuracy of all measurements and dating for the tree core samples. All experimental analyses were completed at the Laboratory of Soil Structure and Minerals, Institute of Geology and Geophysics, Chinese Academy of Sciences. This dataset holds certain research significance for paleoclimate studies in the East Asian monsoon region.
