NASA 1993_AN_NASA Project: Airborne Topographic Mapper Elevation Measurements of Polar Ice

Arctic, Greenland, Antarctic, and Patagonia spot elevation measurements acquired using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data set contains both raw and resampled, smoothed elevation measurements of sea ice and ice surfaces. It is hosted on AWS Open Data and requires an Earthdata Login account for access.

Use Cases

• Modeling ice sheet mass balance and sea level rise based on surface elevation changes.
• Analyzing sea ice thickness and morphology from spot elevation data.
• Calibrating and validating satellite altimetry measurements over ice-covered regions.
• Studying glacial and ice surface topography for geophysical research.

Strengths

• Data covers multiple critical polar and sub-polar regions: Arctic, Greenland, Antarctic, and Patagonia.
• Measurements are acquired using the specialized NASA Airborne Topographic Mapper (ATM) instrumentation.
• Data is available under a permissive CC-BY-4.0 license.
• Includes both raw spot measurements and a processed, resampled, and smoothed product.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
