This dataset collects the day-to-day precipitation data of No.1 glacier No.1 cross section of Urumqi River source in 2002.The hydrological point of No.1 glacier is located in the river channel 300m away from the end of No.1 glacier, and it implements the monitoring of the snow and ice runoff of No.1 glacier.The cross section is at an altitude of 3659m, and the watershed covers an area of 3.34km2, among which the glacier covers an area of 1.74km2.It is a rectangle cross section with concrete (height of 1.0m, width of 1.6m), and the meteorological field is located on the left bank of the cross section. ), the meteorological field is located on the left bank of the section.
The routine hydrological and meteorological observations of the Tianshan Glacier Observation Experimental Station are carried out at the No. 1 glacier hydrological point, the empty ice bucket hydrological point and the general control hydrological point in the source area of the Urumqi River. The three hydrological sections are equipped with self-calculating water level meters, and the flow is measured mainly by the flow meter method, and the instantaneous flow is obtained from the water level-flow relationship line. Meteorological observation items are mainly air temperature, precipitation, humidity, evaporation, ground temperature, sunshine and so on. All observation data are organized according to specifications.
Raw data, unprocessed.
Raw data, good data quality.
