TY - Data T1 - Mass balance line data of Glacier No.1 at the source of Urumqi River, 1958-1995 A1 - LI zhongqin A1 - Feiteng Wang DO - 10.12072/Tianshan.017.2017.db PY - 2020 DA - 2020-12-22 PB - National Cryosphere Desert Data Center AB - Tianshan No.1 glacier is a two branch ice bucket valley glacier, with a length of 2.2 km, an average width of 500 m, an area of 1.828 square kilometers, a maximum thickness of 140 meters, a maximum altitude of 4476 meters, an average annual velocity of about 5 meters, an altitude of 3734 meters at the end of the ice tongue, and an average snow line height of 4055 meters. The annual mass balance of glaciers is zero. The annual accumulation of glaciers above this line is greater than the annual melting, and the annual melting of glaciers below this line is greater than the annual accumulation. The level of glacier mass balance refers to the average value of the total accumulation and total melting of glaciers. It reflects the role of glaciers in the total water balance and represents the dynamics of glacier changes. This data set is the material balance line data of Glacier No.1 at the source of Urumqi River from 1958 to 1995.
