A breakthrough of radar remote sensing of the ocean: the  Surface Water and Ocean Topography (SWOT) Mission

Remote sensing of Earth’s surface water is crucial to the study of climate change and its impact to society.  Radar remote sensing is particularly important because it penetrates cloud cover, providing observations under all weather conditions.  Forty years ago, Seasat, the first satellite designed for studying the ocean ...

The Surface Water and Ocean Topography Mission (SWOT): the Ka-band Radar Interferometer (KaRIn) for water level measurements at all scales

SPIE Proceedings, 2010
The Surface Water and Ocean Topography (SWOT) mission will study ocean mesoscale and submesoscale phenomena and provide an inventory of storage change and discharge for fresh water bodies and rivers. In this paper, we examine the combination of measurements that will be used by SWOT to achieve a globally consistent data set.

More Than Just Surface Water Topography: Phenomenology Studies for the Surface Water and Ocean Topography (SWOT) Mission

The Synthetic Aperture Radar (SAR) frequency on the Surface Water and Ocean Topography (SWOT) Mission is Ka-band: 35.75 GHz, which equates to an approximately 8mm wavelength. This is a relatively high-frequency system compared with the C-band on the now-ubiquitous Sentinel-1 or the L-band from UAVSAR and soon-to-launch NISAR Mission.

Validation of Surface Water and Ocean Topography (SWOT) river Water Surface Elevation using in-situ gauges in Finnish rivers

Rivers in cold-climate regions are fundamental components of coupled hydrological, cryospheric, and ecological systems by governing water availability, ecosystem functioning, and human activities under strong seasonal constraints. Snow accumulation, river ice processes, and freeze-thaw cycles are major factors for tightly controlling river dynamics ...

Validation of Water Surface Elevation and Extent over French lakes using the Surface Water Ocean Topography (SWOT) mission

Natural lakes and artificial reservoirs—collectively referred to as lakes—are a fundamental component of terrestrial hydrology and play a vital role in supporting ecological processes, sustaining terrestrial biodiversity, regulating biosphere functioning, and facilitating a wide range of human activities (Wang et al., 2025).

Evaluating the potential of Surface Water and Ocean Topography (SWOT) satellite data for detecting water-surface superelevation in meandering rivers

Lateral water-surface superelevation, i.e., the rise in water level along the outer bank, is a common phenomenon in meandering rivers caused by the curvature-induced centrifugal force. Accurate data on water-surface superelevation are critical for modeling the hydrodynamics of meandering rivers, including free surface deformation and prediction of mean

Surface Water and Ocean Topography (SWOT) validation of wide swath interferometry over the lakes in the Pyrénées

The Surface Water and Ocean Topography (SWOT) mission, launched in December 2022 is aiming to produce Water Surface Elevation (WSE) over lakes larger than 250*250 m, globally, with high accuracy better than 25 cm (1σ). Water extent of lakes is also measured with requirements to perform it with a relative accuracy better than 15% of the total lake ...
