本数据是天山乌鲁木齐河源头乌鲁木齐1号冰川的长期物质平衡数据汇编，记录了该冰川自1958年以来的年度质量平衡结果。该流域的乌鲁木齐1号冰川是世界冰川监测服务组织（WGMS）重点监测的10个冰川之一，不仅是中国、中亚地区的代表冰川，也是世界上为数不多的观测时间超过50年的冰川。本数据集的目的是：（1）反映乌鲁木齐一号冰川质量平衡的变化趋势；（2）为从事冰川质量平衡对比验证和模型模拟的同行提供方便。

The purpose of this dataset is to (1) reflect the trends in the mass balance of Urumqi Glacier No. 1 and (2) to provide convenience to colleagues working on comparative validation and modelling of the glacier mass balance.
