Tidal Modulation of Waves Around the Aleutian Islands

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Forming a critical part of the North Pacific Great Circle Route, the narrow passes of the Aleutian Islands are considered among the United States' most treacherous waters for maritime navigation. This study investigates the tidal modulation of surface gravity waves throughout the archipelago using a high‐resolution, unstructured‐grid, coupled ...

A Semi-Analytical Model for Delay/Doppler Altimetry and Its Estimation Algorithm [PDF]

open access: yes, 2014
International audienceThe concept of delay/Doppler (DD) altimetry (DDA) has been under study since the mid-1990s, aiming at reducing the measurement noise and increasing the along-track resolution in comparison with the conventional pulse-limited ...

Recent Observations of Thwaites Glacier, West Antarctica Are Consistent With High Rates of Loss in Next 50 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Thwaites Glacier has experienced accelerating mass loss, with rates increasing over fivefold since the 1990s. We apply transient calibration to two independent ice‐sheet models (STREAMICE and ISSM) using time‐varying velocity and surface elevation data from 2004 to 2017 to project future mass loss through 2067.

Arctic High Resolution Sea‐Ice Forecast System on a Heterogeneous Many‐Core Computing Platform

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This study develops an ensemble forecast system for Arctic sea ice with a horizontal resolution of ∼2 km to resolve linear kinematic features (LKFs). The system is designed to run operationally on the Sunway computing architecture, which employs many‐core processors with a distinct programming logic.

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

open access: yesRemote 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 ...

Integrating SWOT With Multi‐Source Satellite Observations for Near‐Daily Reservoir Water Level Monitoring

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Reservoirs play a crucial role in global water resource management. Monitoring reservoir hydrologic dynamics is critical for assessing climate variability and anthropogenic regulation. However, traditional satellite altimetry faces multiple challenges hindering high frequency and accuracy water level monitoring.

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

open access: yesThe 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 ...

Detection and Characterization of Ship Targets Using CryoSat-2 Altimeter Waveforms [PDF]

open access: yesRemote Sensing, 2016
This article describes an investigation of the new possibilities offered by SAR altimetry compared with conventional altimetry in the detection and characterization of non-ocean targets. We explore the capabilities of the first SAR altimeter installed on the European Space Agency satellite CryoSat-2 for the detection and characterization of ships.
