Ice Temperature and Subglacial Conditions Model for WAIS Divide

A 2000 model study provides spatial variations of ice temperature and subglacial conditions near the Ross and Amundsen flow divide of the West Antarctic Ice Sheet. The data set includes attenuation estimates for individual radar profiles, derived from ice-penetrating radar data collected by the University of Texas and University of Washington. It was published by AMD_USAPDC and last updated in April 2010.

Use Cases

• Model spatial ice temperature variations using radar-derived attenuation estimates.
• Analyze subglacial conditions near the Ross and Amundsen flow divide from the radar profile data.
• Validate ice sheet models with specific attenuation rates and temperature values for the WAIS Divide region.

Strengths

• Data is based on ice-penetrating radar surveys from a major 2000 aerogeophysical campaign.
• Provides model outputs for a key future deep ice coring site in West Antarctica.

Limitations

• Data recency is limited, with a last update in 2010.
• Specific sample size, row count, and column details are unknown.
• Data availability is restricted to MATLAB and PDF formats, which may limit accessibility.
