NASA 2017_GR_NASA Project: Gravity and Lidar Data Over Greenland and Antarctica

Gravity measurements and surface elevation data collected over Greenland and Antarctica by the Lamont-Doherty Earth Observatory Gravimeter Suite and the NASA Land, Vegetation, and Ice Sensor (LVIS). The data were gathered during NASA Operation IceBridge funded campaigns. Data is hosted on AWS and requires an Earthdata Login account for access.

Use Cases

• Modeling ice sheet mass changes based on gravity anomaly measurements.
• Analyzing surface elevation and ice topography changes based on airborne lidar data.
• Calibrating satellite altimetry data using the high-resolution LVIS lidar measurements.
• Studying glacial isostatic adjustment and bedrock geology from gravity data.

Strengths

• Data originates from authoritative NASA Operation IceBridge campaigns and the Lamont-Doherty Earth Observatory.
• Combines two complementary sensor types (gravimeter and lidar) for a multi-faceted geophysical view.
• Released under a permissive CC-BY-4.0 license.

Limitations

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