Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Monitoring small rivers during extreme events is challenging, especially in remote areas. This study assesses the accuracy of the Surface Water and Ocean Topography (SWOT) mission in characterizing an extreme hydrological event on a narrow river (∼60 m wide), using a landslide‐induced flood on the Chilcotin River (Canada) as a case study. SWOT

SPECTRASAT: A concept for the collection of global directional wave spectra [PDF]
, 1984 The synthetic aperture radar (SAR) imagery from SEASAT revealed a rich tapestry of backscatter patterns from the surface of the ocean. Although still far from being fully understood, these patterns occurred on nearly all spatial scales accessible to the ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

Sensors, 2006 The main limitations of standard nadir-looking radar altimeters have been knownfor long. They include the lack of coverage (intertrack distance of typically 150 km for theT/P / Jason tandem), and the spatial resolution (typically 2 km for T/P and Jason),

Diurnal Temperature Variability at Latitudinally Distinct Sites on the Moon
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract The thermophysical environment of the Moon plays a crucial role for future exploration, resource utilization and also in understanding its geological evolution. While global‐scale surface temperature distributions have been reasonably well constrained through numerical modeling and orbiter observations, recent in situ measurements have ...

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,

Balancing Backscatter and Diffusion in a 1/4° Forced Global Ocean Model
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.Abstract Mesoscale ocean eddies in 1/4° ${}^{\circ}$ global ocean models lie near the grid scale and are overdamped by viscosity, leading to reduced eddy kinetic energy, weak sea surface height variability, and mean‐state biases. Backscatter has been proposed to remedy this problem by re‐injecting dissipated energy, but its diabatic consequences are ...

Monitoring Flood Inundation Dynamics From Space
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.
