Snow is the most reflective, and also the most insulative, natural material on Earth.
Consequently, it is an integral part of the sea-ice and climate systems. However, the spatial …

Spaceborne radar altimeters record echo waveforms over all Earth surfaces, but their
interpretation and quantitative exploitation over the Arctic Ocean is particularly challenging …

We present a first examination of Arctic sea ice snow depth estimates from differencing
satellite lidar (ICESat‐2) and radar (CryoSat‐2) freeboards. These estimates cover the …

Abstract National Aeronautics and Space Administration's (NASA's) Ice, Cloud, and land
Elevation Satellite‐2 (ICESat‐2) mission was launched in September 2018 with the primary …

ESA's CryoSat‐2 has transformed the way we monitor Arctic sea ice, providing routine
measurements of the ice thickness with near basin‐wide coverage. Past studies have shown …

We offer a view of the Antarctic sea ice cover from lidar (ICESat-2) and radar (CryoSat-2)
altimetry, with retrievals of freeboard, snow depth, and ice thickness that span an 8-month …

Abstract The Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL) mission is
one of six high-priority candidate missions (HPCMs) under consideration by the European …

Sea ice thickness is a critical variable, both as a climate indicator and for forecasting sea ice
conditions on seasonal and longer time scales. The lack of snow depth and density …

Arctic sea ice is diminishing with climate warming at a rate unmatched for at least 1,000
years. As the receding ice pack raises commercial interest in the Arctic, it has become more …

A large retreat of sea-ice in the 'stormy'Atlantic Sector of the Arctic Ocean has become
evident through a series of record minima for the winter maximum sea-ice extent since 2015 …
