Mapping the spatial structure of storm surges with Swot
Swot can map the spatial structure of storm surges across diverse oceanic regimes

Analyzing Swot data collected during three extreme weather events, a paper published on Geophysical Research Letter demonstrates the capability of Swot to capture the spatial structure of storm surges across diverse oceanic regimes. Results confirm how Swot represents a major advancement in coastal oceanography, with strong potential to improve scientific understanding, risk assessment, and long‐term coastal resilience. An interview with Diego Vega-Giménez, first author of the study.
