The increasing quality and quantity of information provided by Copernicus (the European Union Programme funneling Earth Observation and in situ data into a broad set of information services) offer the possibility to analyse and predict coastal meteooceanographic processes at an unprecedented level. A decisive step in this direction is presently being supported by the launch of the Sentinel satellite constellation started in April 2014 and deemed to be completed in 2020. The overall fleet is composed by a set of six families of devices, each addressing different aspects of atmosphere, ocean and land monitoring. The new resolution in space, coverage in time, combinations of sensors offered by satellite Sentinel family will be providing a unique opportunity to develop the Copernicus coastal dimension and to tackle the pressures of increasing population and activities threatening the sustainability of coastal resources and infrastructures. The combination of ocean/atmosphere/land observations made available in particular from the Sentinel (S) 1/2/3 satellites, aligned with the capabilities of an increasing number of high-resolution numerical systems (more specifically, coupled atmospheric, wave and current ones) within the Copernicus Marine Environment Monitoring Service (CMEMS) catalogue, should then allow users to access improved representations of the coastal environment.
