Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Characterizing ICESat‐2 Snow Depths Over the Boreal Forests and Tundra of Alaska in Support of the SnowEx 2023 Campaign

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Recent studies show that the Ice, Clouds, and Land Elevation Satellite‐2 (ICESat‐2) can achieve decimeter‐level accuracy over forested and mountainous sites in the western United States, as well as over the glaciers of Alaska. However, there has yet to be an assessment on ICESat‐2 snow depths over the boreal forests and tundra of Alaska, both ...
