It was established that 26,089 and 28,953 glacial lakes in HMA, with sizes of 0.0054–5.83 km2, covered a combined area of 1692.74 ± 231.44 and 1955.94 ± 259.68 km2 in 1990 and 2018, respectively. The current glacial lake inventory provided fundamental data for water resource evaluation, assessment of glacial lake outburst floods, and glacier hydrology studies in the mountain cryosphere region.","doi":"10.11888/Glacio.tpdc.270919","projection":"Albers","language":"en","share_type":"online","east":104.0,"west":68.0,"south":27.0,"north":55.0,"scale":null,"crs":null,"filesize":63.23,"share_policy":"a","ts_created":"2019-12-31T17:11:04.439570+08:00","doi_type":"拥有自主知识产权","ts_updated":"2021-04-19T10:16:36.846957+08:00","time_description":"1986-07-01 到 1995-08-31, 2016-09-01 到 2019-05-31","datas_group":3,"time_description_en":"1986-07-01 to 1995-08-31, 2016-09-01 to 2019-05-31","data_format":null,"project":[10,11],"specials":[],"cite":null,"review_status":5,"review_invite":[{"user_name":"余武生","username":"isotope","email":"yuws@itpcas.ac.cn","is_cancel_expert":false}],"review_editor":{"id":42421,"last_login":"2022-04-08T15:16:51.670544+08:00","username":"任慧霞","email":"510727846@qq.com","is_active":true,"is_staff":true,"user_name":"任慧霞"},"data_sources":null,"temporal_resolution":"Yearly","spatial_resolution":"10m - 100m","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[264,265,266],"subtopics":{"metadata":"862a34a4-b816-4a49-b218-302db124ca84","three_pole":null,"third_pole":null},"username":"","review_time":"2020-01-02T14:53:29.932221+08:00","protected_duration":null,"protected_describe":null,"is_important":false,"hit_count":2223}
