Funded by the European Space Agency, EOatSEE aims to provide an advanced reconstruction of the relevant processes included in extreme sea level events and its related coastal hazards. Bringing together the EO data provider and the coastal modelling communities, the project tackled key scientific challenges exploiting the latest available space technology. As the project comes to an end in July 2024, the new methods and solutions benchmarked within it shall foster increased coastal resilience in face of a changing climate.
