Block-Circulant Approximation of the Precision Matrix for Assimilating SWOT Altimetry Data

Remote Sensing
The recently deployed Surface Water and Ocean Topography (SWOT) mission for the first time has observed the ocean surface at a spatial resolution of 1 km, thus giving an opportunity to directly monitor submesoscale sea surface height (SSH) variations ...

Unveiling the First Impressions of the Wide‐Swath Altimetry SWOT Mission Over the Ganga River, India

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The Surface Water and Ocean Topography (SWOT) mission offers novel global observations of river hydrodynamics, yet its performance across varied river morphologies remains understudied. We evaluate SWOT node and raster products over a ∼210 km stretch of the Ganga River, India, during the fast‐sampling phase, using GNSS‐based continuous ...

Coastal data accumulation potentials for operational systems using airplanes [PDF]

Potential users of SEASAT for remote sensing of coastal zone phenomena have established a need for resolutions beyond those attainable with SEASAT-A. One method of obtaining higher resolutions would be to fly the instruments aboard airplanes rather than ...

Data-Driven Calibration of SWOT’s Systematic Errors: First In-Flight Assessment

Remote Sensing
The SWOT satellite, carrying the KaRIN first wide-swath onboard altimeter, was launched in December 2022, and has now delivered more than a year of surface water elevation data over the ocean and inland lakes/rivers. These data are affected by systematic
