This dataset contains the variation data of glacier meltwater in the Aksu Basin of the Tomur Peak area from 1959 to 2017. The time resolution is monthly, and the spatial resolution is based on the glacier vector map and 90m × 90m digital elevation model (SRTDMEM) in the basin. The glaciers in the Aksu Basin are divided into several elevation zones at 100m elevation intervals, and the glacier meltwater in each elevation zone of the basin is calculated. The total amount of glacier meltwater is obtained through area weighting. This data can provide support for regional water resource management.", "ds_time_res": "月", "ds_acq_place": "Aksu River Basin in the Tuomu'er Peak area of Tianshan Mountains", "ds_space_res": "100", "ds_projection": "", "ds_process_way": "
Based on meteorological station data (daily precipitation and temperature) provided by the National Climate Data Center, combined with the 90 m × 90 m digital elevation model (SRTM DEM) and the second glacier cataloging vector data, the historical evolution characteristics of glacier meltwater and its components in the Aksu Basin of the Tomur Peak area from 1959 to 2027 were reconstructed using the degree day factor model, including rainfall runoff, snowmelt runoff, and meltwater runoff from the glacier area. Firstly, divide the glaciers in the watershed into different height zones at intervals of 100 meters; Secondly, based on data from meteorological stations in and around the Yangtze River and Yellow River basins, monthly temperature and precipitation data at the end of glaciers were obtained through spatial interpolation. Combined with temperature decline rate and precipitation gradient, monthly temperature and precipitation within each elevation zone were calculated. The degree day model was used to output the accumulation, melting, material balance, and meltwater of glaciers in each elevation zone. Finally, the total amount and components of glacier meltwater in the basin (meltwater runoff, rainfall runoff, and snowmelt runoff) were obtained by weighting the meltwater runoff and area of each elevation zone.", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 0, "license_type": "CC BY 4.0", "ds_topic_tags": [ "度日模型", "冰川融水径流", "月尺度", "年际变化" ], "ds_subject_tags": [ "水文学" ], "ds_class_tags": [], "ds_locus_tags": [ "天山托木尔峰地区" ], "ds_time_tags": [ 1959, 1960, 1961, 1962, 1963, 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 ], "ds_contributors": [ { "true_name": "许民", "email": "xumin@lzb.ac.cn", "work_for": "中科院西北生态环境资源研究院", "country": "中国" }, { "true_name": "王鹏寿", "email": "wangpengshou11@163.com", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "许民", "email": "xumin@lzb.ac.cn", "work_for": "中科院西北生态环境资源研究院", "country": "中国" } ], "ds_managers": [ { "true_name": "许民", "email": "xumin@lzb.ac.cn", "work_for": "中科院西北生态环境资源研究院", "country": "中国" } ], "category": "水文" }
