Non-uniform phase filter for Tiangong-2 Interferometric Imaging Radar Altimeter

The Journal of Engineering, 2019
The interferometric imaging radar altimeter (InIRA) on-board Chinese Tiangong-2 space laboratory is a Ku-band interferometric radar whose major aim is to measure the wide-swath ocean topography. Unlike traditional interferometric synthetic aperture radar

Revealing Coastal Storm‐Wave Transformations From SWOT HR Observation: The English Channel Case Study

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.

A Multi‐Scale Probabilistic Machine Learning Model for Balanced and Unbalanced Sea Surface Height Decomposition

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Sea surface height (SSH) reflects a superposition of balanced motions (BM) and unbalanced motions (UBM), which play distinct roles in ocean dynamics and energetics. The Surface Water and Ocean Topography (SWOT) satellite provides two‐dimensional SSH maps at spatial resolutions where BM and UBM coexist, but its 21‐day repeat cycle precludes ...

Remotely Sensed Surface Water Storage Shows Distinct Patterns From SWAT‐Simulated Data

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Quantifying and projecting the downstream benefits of water stored in lakes and wetlands (SWstorage) requires watershed hydrologic models, which often parameterize surface water storage in topographic depressions using static digital elevation model (DEM) data.

Ocean Circulation Modulating the Nutrient Distribution and Fluxes at Regional and Fine Scales: A Case Study in the Northwestern Mediterranean Sea

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract In the oligotrophic ocean, nutrient distribution plays a key role in controlling primary production via upward fluxes. In spring 2023, the BioSWOT‐Med cruise investigated how fine‐scale ocean dynamics influence nutrient availability in the Mediterranean Sea.

CryoSat-2 swath interferometric altimetry for mapping ice elevation and elevation change [PDF]

, 2018
For more than 25 years, satellite radar altimetry has provided continuous information on the state of the cryosphere and on its contribution to global sea-level rise.

Hidden Fine‐Scale Transport Pathways and Biological Connectivity Revealed by SWOT

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Oceanic currents redistribute nutrients, phytoplankton, and other biogenic materials, fundamentally shaping marine biodiversity and ecosystem functioning. Yet, the topology of fine‐scale material transport remains poorly resolved due to limitations in high‐resolution flow observations.
