Sea Ice Elevation in the Western Weddell Sea, Antarctica: Observations From Field Campaign
Sea ice elevation is crucial in the characterization of three-dimensional (3D) sea ice patterns, providing physical insights to advance sea ice dynamic models. Moreover, how sea ice elevation may be related to the ocean geophysical environment is still a significant knowledge gap, especially in Anta...

Sea ice elevation is crucial in the characterization of three-dimensional (3D) sea ice patterns, providing physical insights to advance sea ice dynamic models. Moreover, how sea ice elevation may be related to the ocean geophysical environment is still a significant knowledge gap, especially in Antarctica. A radar theory relating electromagnetic scattering mechanisms to sea ice elevation over old and deformed rough ice has been reported in a prior companion paper. This follow-up paper presents the validated model function and synthetic aperture radar (SAR)-retrieved sea ice elevations based on the field data acquired during the Operation IceBridge and TanDEM-X Antarctic Science Campaign. A high-resolution sea ice digital elevation model (DEM) is generated extensively over a 19 × 450 km sector in the Western Weddell Sea, achieving a good accuracy with a low root-mean-square error of 0.23 m.
