Sign in to view source links and access this dataset
Description
Radar depth sounder measurements of ice elevation, surface, bottom, and thickness for Greenland and Antarctica. The data were collected via the Multichannel Coherent Radar Depth Sounder (MCoRDS) during NASA's Operation IceBridge funded aircraft survey campaigns. It is hosted on AWS Open Data and requires an Earthdata Login account for access.
Use Cases
Modeling ice sheet dynamics and sea-level rise projections based on ice thickness measurements.
Analyzing changes in ice surface elevation over time for climate monitoring.
Mapping subglacial topography and bedrock features based on ice bottom data.
Calibrating and validating satellite-based ice thickness estimates with in-situ radar data.
Strengths
Data originates from NASA's Operation IceBridge, a major airborne survey campaign.
Covers two critical polar regions: Greenland and Antarctica.
Includes multiple related ice properties: elevation, surface, bottom, and thickness.
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.
