IceBridge UAF Lidar: Alaska Glacier Surface Elevation Profiles

Surface elevation profiles of Alaska glaciers were collected by the University of Alaska Fairbanks airborne Glacier Lidar system. The data were gathered as part of NASA's Operation IceBridge funded aircraft survey campaigns. The dataset was last updated on March 5, 2026.

Use Cases

• Model glacier mass balance based on surface elevation profiles.
• Monitor topographic changes in Alaskan glaciers over time based on repeated airborne surveys.
• Validate satellite-derived elevation measurements for glaciers based on high-resolution lidar data.

Strengths

• Data originates from a dedicated airborne lidar system operated by the University of Alaska Fairbanks.
• Dataset is associated with NASA's Operation IceBridge, a major airborne survey campaign.
• Last updated on 2026-03-05, suggesting recent metadata maintenance.

Limitations

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