Spatial and Temporal Variability in Global River Slopes from the Surface Water and Ocean Topography (SWOT) Satellite

River water surface slope (WSS) is fundamental for hydrologic, hydraulic, and geomorphic modeling. Unlike channel bed slope, often treated as short-term stationary, WSS varies dynamically as flow interacts with bed heterogeneity. We analyze global spatial and monthly patterns of WSS using the SWOT Level 2 River Single-Pass Vector data (within 2023/08 –

Phase‐Resolved Swells Across Ocean Basins in SWOT Altimetry Data: Revealing Centimeter‐Scale Wave Heights Including Coastal Reflection

Geophysical Research Letters
Severe storms produce ocean waves with periods of 18–26 s, corresponding to wavelengths 500–1,055 m. These waves radiate globally as swell, generating microseisms and affecting coastal areas.
