High-resolution Antarctic sea-ice thickness and snow depth from drift-aware multi-mission altimetry

Wide-Swath Mapping of Antarctic Sea-Ice Height and Freeboard From SWOT Ka-Band Interferometry: Comparison Using ICESat-2

The surface water and ocean topography (SWOT) mission provides Ka-band wide-swath interferometric altimetry, enabling two-dimensional (2-D) observations of polar sea ice. This study presents one of the first large-scale Antarctic assessments of SWOT-derived sea-ice surface height and freeboard through near-coincident c...

A long-term wintertime snow depth dataset on Arctic sea ice (1978-2025) derived from multisource passive microwave radiometer data

Altimetric Ku-band Radar Observations of Snow on Sea Ice Simulated with SMRT

Pan-Antarctic evaluation of National Snow and Ice Data Center (NSIDC) sea ice drift product using high-resolution SAR and buoy data

The recent historic minima in Antarctic sea ice extent suggest the possibility of new thermodynamic and dynamic conditions across the Southern Ocean. In investigating these thermodynamic and dynamic sea ice behaviors, it is essential to observe sea ice drift with high quality. However, while the relatively abundant a...

Satellite‐Derived Volume Budget of Antarctic Sea Ice

In recent years, the Antarctic has seen a notable shift in sea ice trends: Where sea ice extent and volume were increasing on average, they have shown an unprecedented decline since 2016. Understanding the drivers of this shift is crucial to determining the impacts of climate change on sea ice and improving modeling...

Variability of internal snow properties over Antarctic late summer sea ice on different spatial scales

Snow on Antarctic sea ice strongly affects thermodynamic processes, sea ice mass balance, and microwave remote sensing, yet its spatial variability and characteristic length scales remain poorly quantified. The aim of this study is to provide a spatially extensive, layer-resolved characterization of Antarctic late-summ...
