Global Glacier-Free Topography, Ice Thickness, and Potential Future Lake Depth

Output data from the study "Global glacier-free topography reveals large potential for future lakes in presently ice-covered terrain". The dataset contains three GeoTIFF outputs for each glacier on Earth: subglacial topography, ice thickness, and potential lake depth if all ice melted. The data was authored by Thomas Frank and last updated on 2026-05-03.

Use Cases

• Modeling future hydrological systems based on potential lake depth data.
• Analyzing subglacial terrain and bedrock topography for geological studies.
• Estimating global ice volume and sea-level rise contributions based on ice thickness data.
• Mapping the potential location and extent of future proglacial lakes.

Strengths

• Data covers all glaciers on Earth, providing a global scope.
• Includes three distinct modeled outputs: topography, ice thickness, and lake depth.
• Files are provided in the GeoTIFF format, a standard for geospatial data.
• Dataset size is 1.1 GB, indicating substantial spatial detail.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
