Satellite altimetry continues to revolutionize ocean science, enabling precise observations of geocentric sea level with near-global coverage. However, altimetry has traditionally been challenged in the coastal zone (within 20 km of land) due to the presence of land in the altimeter and radiometer footprint. As the oceans further encroach on coastal communities, a more detailed understanding of the physical processes impacting sea-level variability as it propagates landward is needed. State-of-the-art satellite altimeters have the potential...
