Evaluating Arctic Thin Ice Thickness Retrieved from Latest Version of Multisource Satellite Products

Remote Sensing
Currently, the performance of sea ice thickness (SIT) data retrieved from multisource satellite products in the Arctic seasonal ice zones remains unclear. This study presented the spatiotemporal intercomparison and evaluation of satellite data, including

Anatomy of Interannual to Decadal Sea Level Changes in the GECCO3 Ocean Synthesis

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The GECCO3 synthesis is used to infer a dynamically consistent decomposition of sea level changes (variability and trends) on interannual to decadal time scales. Over most parts of the global ocean equatorward of 60° latitude, sea level variability and trends can be explained almost completely by the upper ocean (above 2,000 m) steric ...

ANTARCTIC ICE SHEET SURFACE MASS BALANCE ESTIMATES FROM 2003 TO 2015 USING ICESAT AND CRYOSAT-2 DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
An assessment of Antarctic ice sheet surface mass balance from 2003 to 2015 has been carried out using a combination of ICESat data from 2003 to 2009 and CryoSat-2 data from 2010 to 2015.

Anomalous Sea Ice Retreat in the Refreezing Western Arctic by a 30‐Year Record Cyclone in October: Oceanic, Atmospheric, and Wave Influences

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An extreme Arctic cyclone (AC) in October 2022 reached a record‐low pressure of 955 hPa and caused unusual wave‐induced sea‐ice breakup in the Canada Basin, making it the strongest event in the western Arctic in 30 years. Here we examine how this event interrupted freeze‐up by quantifying sea‐ice retreat associated with atmospheric and oceanic

River Levels Derived with CryoSat-2 SAR Data Classification—A Case Study in the Mekong River Basin

Remote Sensing, 2017
In this study we use CryoSat-2 SAR (delay-Doppler synthetic-aperture radar) data in the Mekong River Basin to estimate water levels. Compared to classical pulse limited radar altimetry, medium- and small-sized inland waters can be observed with CryoSat-2

Retracking Cryosat-2 Data in SARIn and LRM Modes for Plateau Lakes: A Case Study for Tibetan and Dianchi Lakes

Remote Sensing, 2021
This paper estimates lake level variations over two small and adjacent lakes in the Tibetan plateau (TP), namely Gemang Co and Zhangnai Co, as well as the inland Dianchi Lake in China using CryoSat-2 SARIn-mode and LRM 20-Hz waveforms over the period of ...

First Assessment of ICESat‐2 Summer Sea Ice Freeboard With Airborne Validation

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract ICESat‐2 has demonstrated solid performance in retrieving sea ice freeboard during winter, when sea ice surface types are well‐defined and leads provide reliable sea surface height references. Summer retrievals are challenging because melt ponds are not explicitly distinguished in the ATL07 surface classification and may be identified as ice ...

CryoSat-2 satellite radar altimetry for river analysis and modelling [PDF]

, 2017
Der findes, på globalt plan, ikke tilstrækkelige observationer af overfladevand og deres dynamikker til at kunne forvalte vandressourcerne. Samtidig er tilgængeligheden af data faldende, grundet manglende in-situ observationer og deling af eksisterende ...

Impact assessment of snow thickness, sea ice density and water density in CryoSat-2-derived sea ice thickness [PDF]

The Cryosphere
Sea ice thickness is an essential climate variable, which is often derived from satellite altimetry freeboard estimates, e.g., by CryoSat-2. In order to convert freeboard to sea ice thickness, assumptions are needed for snow thickness, snow density, sea ...

Variability of Arctic sea ice thickness and volume from CryoSat-2 [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
We present our estimates of the thickness and volume of the Arctic Ocean ice cover from CryoSat-2 data acquired between October 2010 and May 2014. Average ice thickness and draft differences are within 0.16 m of measurements from other sources (moorings, submarine, electromagnetic sensors, IceBridge).
