本数据为论文《Global glacier-free topography reveals large potential for future lakes in presently ice-covered terrain》的研究成果。研究方法详见原文。\n
针对全球每一处冰川，本数据集共生成三类成果数据：冰下地形（Topg）、冰川厚度（Thk）、冰川完全消融后潜在湖泊水深（Lakes）。三类数据分别对应同名压缩包，包内按RGI 冰川分区建立子文件夹，各分区文件夹中存放该区域所有冰川的 GeoTIFF 格式成果文件。\n
连片分布的冰川采用统一网格开展模拟，因此单份成果文件可能对应多座冰川，部分冰川看似缺失文件亦属正常情况。如需查询各冰川对应的成果文件，可查看Glacier_lookup_tables.zip文件。该文件按 RGI 分区整理对照表，将各冰川编号与对应成果文件所属主冰川编号进行关联。\n
举例说明：冰川编号 RGI60-02.17594 关联至编号 RGI60-02.00001，代表前者与后者共用同一模拟网格，二者的冰川厚度、冰下地形、潜在湖泊水深数据，均可在文件RGI60-02.00001_*.tif中查找（后缀*对应 thk、topg、lakes）。", "ds_source": "", "ds_process_way": "", "ds_quality": "", "ds_acq_start_time": null, "ds_acq_end_time": null, "ds_acq_place": "全球", "ds_acq_lon_east": null, "ds_acq_lat_south": null, "ds_acq_lon_west": null, "ds_acq_lat_north": null, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "open-access", "ds_total_size": 1191984662, "ds_files_count": 0, "ds_format": "GeoTIFF", "ds_space_res": "", "ds_time_res": "", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "2d43e434-d207-41d1-8a87-11f850389dd6.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "a4dd5849-78f2-44c5-b0f1-3450e952b2a2", "ds_serv_man": null, "ds_serv_phone": null, "ds_serv_mail": null, "doi_value": "", "subject_codes": [ "170.45", "170.55" ], "quality_level": 0, "publish_time": "2026-06-15 10:31:05", "last_updated": "2026-06-15 10:31:05", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.ncdc.glacier.db7454.2026", "i18n": { "en": { "title": "Global glacier-free topography reveals large potential for future lakes in presently ice-covered terrain", "ds_format": "GeoTIFF", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
This is the output data of the study \"Global glacier-free topography reveals large potential for future lakes in presently ice-covered terrain\". For details on the methods, see the manuscript. \r\n
Three different outputs are produced for each glacier on Earth: - Subglacial topography (Topg) - Ice thickness (Thk) - Lake depth of lakes that could form if all glacier ice were to melt (Lakes) The three .zip files with the above names contain folders for each RGI region, which in turn contain the output files (GeoTiffs) for all glaciers in that region.\r\n
Since connected glaciers were modeled on one grid, one output file may cover several glaciers, whereas other glaciers may be seemingly missing. The latter is not the case. To look up which glacier is covered by which output file, refer to the Glacier_lookup_tables.zip file containing, for each RGI region, a table that links each glaciers RGI ID with the RGI ID of the glacier under which the output can be found. \r\n
For instance, the RGI ID RGI60-02.17594 is associated with the RGI ID RGI60-02.00001. This implies that the former glacier was modeled on the grid of the latter glacier, and that the output for both glaciers is found by locating the file RGI60-02.00001_*.tif where * can be thk, topg, or lakes.", "ds_time_res": "", "ds_acq_place": "global", "ds_space_res": "", "ds_projection": "", "ds_process_way": "", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 0, "recommendation_value": 0, "license_type": "https://creativecommons.org/licenses/by/4.0/", "doi_reg_from": "reg_local", "cstr_reg_from": "reg_local", "doi_not_reg_reason": null, "cstr_not_reg_reason": null, "is_paper_in_submitting": false, "belong_to_nieer": false, "ds_topic_tags": [ "冰川退缩", "冰下地形", "冰川厚度", "湖泊水深" ], "ds_subject_tags": [ "地理学", "水文学" ], "ds_class_tags": [], "ds_locus_tags": [ "全球" ], "ds_time_tags": [], "ds_contributors": [ { "true_name": "T.
