SWOT-derived high-resolution lake surface topography for enhanced lake water level retrieval

GIScience & Remote Sensing
Lake water level is a fundamental variable for water-resources monitoring and hydrodynamic modeling. Although a lake surface is conventionally assumed to be flat and level, satellite altimetry measurements referenced to the ellipsoidal height system ...

Assessing Dynamical Contributions to SWOT Sea Surface Height in an Internal Tide Hotspot

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission has revealed high‐frequency sea surface height anomaly (SSHA) variability associated with internal gravity waves, yet comparison with in situ observations remains limited. Here, we analyze a mooring array beneath the swaths of SWOT Cal/Val south of New Caledonia, an internal tide (IT ...

Evaluating SWOT in the Coastal Zone: Comparisons With Tide Gauge and Airborne LiDAR in the Bristol Channel and Severn Estuary, UK

Geophysical Research Letters
Traditional nadir altimeters struggle with coastal water surface elevation (WSE) measurement and fine‐scale river‐estuary interactions, due to land‐water signal interference and their wide inter‐track spacing.

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
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 ...
