IceBridge Ku-Band Radar Echo Profiles for Polar Ice Sheets

Radar altimeter data provides elevation and surface measurements over Greenland, the Arctic, and Antarctica. The dataset includes flight path charts and echogram images acquired by the Center for Remote Sensing of Ice Sheets (CReSIS). It is published by the NSIDC and has been updated as recently as 2026.

Use Cases

• Analyzing ice sheet surface elevation changes using geolocated radar echo strength profiles.
• Mapping flight paths and correlating radar measurements with specific geographic locations over polar regions.
• Interpreting subsurface ice layer features from Ku-band radar echogram images.
• Validating satellite-derived ice elevation data with airborne radar measurements.

Strengths

• Data covers major polar ice sheets in Greenland, the Arctic, and Antarctica.
• Includes multiple data types: elevation profiles, flight charts, and echogram images from Ku-band radar.
• Maintained by a recognized organization (NSIDC) with a recent update indicated in 2026.

Limitations

• Specific row counts, file sizes, and a complete column list are unavailable from the provided sources.
• Conflicting 'last updated' dates exist between sources (2012 vs. 2026), creating uncertainty about data currency.
• License information is inconsistent, listed as 'other-license-specified' or 'None', requiring user verification.
