This data set is aimed at Glacier No.1 at the headwaters of Urumqi River in Tianshan Mountains. The data set includes balance year and material balance. The dataset contains six records. The observation method of flower stalk was used. At the end of each year's glacier melting, the exposed height of flower stalks at different positions was measured with tape. Combined with the snow pit profile, the amount of glacier melting and accumulation was calculated, and the net material balance in each balance year was obtained, which was expressed in millimeter water equivalent (mm W.E.). During the observation period, some of the flower stalks were toppled or covered by snow, so the effective data could not be obtained, which had a certain impact on the calculation results of the material balance year. Protocol sharing is adopted. The data set contains two fields: balance year (unit: year) and material balance quantity (unit: millimeter water equivalent (mm W.E.)). The data set is measured year by year from August 2012 to August 2017. The accuracy of material balance calculation results is controlled within 5 mm water equivalent (MMW. E.).
Self generated.

The measurement and calculation process should be standardized and strictly reviewed.
The flower rod observation method was used. 43 flower stalks were arranged between 3750 and 4100 above sea level in Glacier No. 1 at the headwaters of Urumqi River. At the end of the glacier melting, the exposed height of the flower stalks at different positions, as well as the height of the measuring rod, the additional ice thickness, the snow profile and the depth of the polluted layer, were measured with a tape measure.
