Greenland Ice Sheet Radar Echo Profiles from Operation IceBridge

Radar echograms collected over Greenland by the CReSIS Accumulation Radar instrument during Operation IceBridge campaigns. The dataset provides geolocated radar echo strength profiles for studying ice sheet properties. It is managed by the National Snow and Ice Data Center (NSIDC).

Use Cases

• Analyzing internal ice sheet layers and accumulation rates using radar echo strength profiles.
• Mapping basal topography and conditions beneath the Greenland ice sheet.
• Investigating snow and firn properties through radar signal penetration and reflection.
• Calibrating and validating ice sheet models with observed geolocated radar data.

Strengths

• Data originates from the authoritative Operation IceBridge airborne campaigns.
• Provides direct, instrument-measured radar echo profiles for internal ice structure.

Limitations

• Specific row count, file size, and complete column details are unavailable from all sources.
• Sources conflict on the last updated date, reporting both 2012-05-07 and 2026-03-13.
