This data set is the daily meteorological observation data of three hydrological stations from 2003 to 2004, including relative humidity data. This data set can extract the meteorological information of glaciers and study the mass balance of glaciers. The routine hydrological and meteorological observation of Tianshan glacier observation station is carried out at No.1 glacier hydrological point, empty ice bucket hydrological point and general control hydrological point in the source area of Urumqi River. The three hydrological sections are equipped with self gauge water level gauge. The flow measurement is mainly conducted by the current meter method, and the real-time flow is obtained from the water level discharge relationship line. Meteorological observation items mainly include temperature, precipitation, humidity, evaporation, ground temperature, sunshine, etc. All observation data were sorted out according to the standard.
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.
