本数据集主要包括哈萨克斯坦1个点，吉尔吉斯斯7个点（150、151、152、156、160、kyrg001、kyrg002）的树木年轮宽度数据，数据内容包含采样点坐标、采样起始年份、采样人、样本编号、年份、宽度值。数据以.rwl格式存储，可用记事本打开编辑。

", "ds_process_way": "根据测量系统，选择从树皮到树芯或从树芯到树皮的方向进行测量。测量前，要对测量仪校准，将显微镜的十字线与测量平台调整在一条直线上。测量时，不断调整样本确保年轮测量宽度为两条年轮间的垂直距离，即测量台的移动方向与所测树轮边线的圆心在一条直线上（显微镜十字线的纵线始终与树轮边线相切）。在树轮断裂的位置，避免将开裂空隙计入年轮宽度。
", "ds_quality": "宽度数据测量的精度为0.01mm。\n数据产生过程遵循的是QX/T90-2008《树木年轮气候研究树轮采样规范》。
