Challenges and opportunities for coastal altimetry

Satellite altimetry—long established as an essential tool for open-ocean oceanography and sea level studies—is now also supporting diverse applications in the coastal zone. These applications include monitoring storm surges and mapping coastal dynamics, wind, and waves, information that can be assimilated in coastal models.

Advances in data processing, combined with technological progress such as the advent of synthetic aperture radar (SAR) altimetry from CryoSat-2 and Sentinel-3, have yielded more-accurate retrievals of sea level, wave height, and wind speed in the coastal zone. This improved accuracy showcases the importance of satellite SAR altimetry.

The 10th edition of the Coastal Altimetry Workshop series was organized by the European Space Agency (ESA) with additional support from 10 other institutions. This workshop brought together nearly 120 scientists from 28 countries. A SAR altimetry training course for students and young researchers (also organized by ESA) took place in parallel in Florence.
