Comparison of sea-ice freeboard distributions from aircraft data and cryosat-2 [PDF]
, 2012 The only remote sensing technique capable of obtain- ing sea-ice thickness on basin-scale are satellite altime- ter missions, such as the 2010 launched CryoSat-2.

Eddy Kinetic Energy Contribution to Total Ocean Kinetic Energy From Multi‐Satellite Altimetry
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Ocean mesoscale structures play a central role in transporting oceanic properties, accounting for a significant fraction of ocean's total kinetic energy (KE). Using 23 years of a novel multisatellite altimetric estimate, we assess the contribution of eddy kinetic energy (EKE), mean kinetic energy (MKE) and cross terms to the temporal mean and ...

Arctic Sea Ice Thickness Estimation from CryoSat-2 Satellite Data Using Machine Learning-Based Lead Detection [PDF]
, 2016 Satellite altimeters have been used to monitor Arctic sea ice thickness since the early 2000s. In order to estimate sea ice thickness from satellite altimeter data, leads (i.e., cracks between ice floes) should first be identified for the calculation of ...

Long Term Assimilation of Directional Wave Data From CFOSAT in the Wave Prediction Model MFWAM
Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract Recently, satellite wave observations have stepped forward with the innovative measurements from the wave scatterometer SWIM of the CFOSAT mission which provides both the significant wave height (SWH) along‐track at nadir look and the directional wave spectra on off‐nadir incidence angle.

Arctic sea surface height variability and change from satellite radar altimetry and GRACE, 2003–2014 [PDF]
, 2016 Arctic sea surface height (SSH) is poorly observed by radar altimeters due to the poor coverage of the polar oceans provided by conventional altimeter missions and because large areas are perpetually covered by sea ice, requiring specialized data ...

Estimating snow depth over Arctic sea ice from calibrated dual-frequency radar freeboards [PDF]
The Cryosphere, 2018 Snow depth on sea ice remains one of the largest uncertainties in sea ice thickness retrievals from satellite altimetry. Here we outline an approach for deriving snow depth that can be applied to any coincident freeboard measurements after calibration

Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract To satisfy the needs of the Arctic sea ice seasonal prediction in summer, we developed the Arctic Seasonal Prediction System (ArcSPS). This system integrates an Arctic sea ice–ocean–atmosphere coupled model with an ensemble‐based Kalman Filter data assimilation model.

Recent Arctic Sea Level Variations from Satellites [PDF]
, 2016 Sea level monitoring in the Arctic region has always been an extreme challenge for remote sensing, and in particular for satellite altimetry. Despite more than two decades of observations, altimetry is still limited in the inner Arctic Ocean.

Coastal sea level from CryoSat-2 SARIn altimetry in Norway
Advances in Space Research, 2018 Abstract Conventional (pulse-limited) altimeters determine the sea surface height with an accuracy of a few centimeters over the open ocean. Sea surface heights and tide-gauge sea level serve as each other’s buddy check. However, in coastal areas, altimetry suffers from numerous effects, which degrade its quality.
