Snow–Ice Morphological Relationship under Sea Ice Surface Topographic Control: Evidence from In Situ RTK Measurements

Characterizing Snow Depth and Ice Surface Elevation on Subarctic Lakes Using a Multi-Sensor Approach

Snow on lake ice is highly heterogeneous, which influences ice formation and growth as snow acts as an effective thermal insulator. Despite its significance, spatially resolved snow depth measurements remain challenging, as existing methods are typically limited to point observations. This study presents a multi-sensor...

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...

Inter‐Comparison of Snow Depth Over Antarctic Sea Ice From Ocean Reanalyzes and Observations

Snow depth on Antarctic sea ice is a critical climate variable affecting energy and mass balance, yet its observation and modeling remain challenging. We present a systematic intercomparison of snow depth from six ocean reanalysis products, two satellite retrievals, and ship‐based and airborne observational constrain...

Emulating high-resolution distributions of snow depth and density on Arctic sea ice

Influence of sea ice and Greenland’s topography on polar low cases in the Greenland Sea

This study investigates how sea ice concentration and Greenland’s topography influence the development, structure, and intensity of polar lows along Greenland’s east coast under similar synoptic forcing. As Arctic sea ice declines and maritime activity expands, these short-lived but hazardous mesoscale cyclones pos...

Evaluating the Potential of Multisource Snow Depth for Improving ICESat-2 Arctic Sea Ice Thickness Retrieval

The accuracy of pan-Arctic sea ice thickness (SIT) derived from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) primarily depends on the representation of snow depth during the conversion from ICESat-2 laser freeboard to SIT. Here, we systematically assess ICESat-2 Arctic SIT retrievals by combining multiple...
