Coastal altimetry is an important observational resource for a better understanding of coastal oceanographic processes and their dynamic connection between the inland and open ocean. During the last decade significant improvements have been achieved in using satellite radar altimetry near coasts. Advances in processing and new/improved corrections permitted to obtain accurate sea level estimations within few kilometers from the coast. The retrieval of waves and winds in the coastal zone is as yet not as mature as sea level measurements.

The advent of SAR altimetry now permits to achieve higher spatial resolution and better precision than before. However, there is a need to assess the quality and the accuracy of these new data sets in order to gain the proper confidence in their operational usage. HYDROCOASTAL, a project funded by ESA, aims at maximizing exploitation of SAR measurements in the coastal zone and inland waters, by evaluating and implementing new approaches to process SAR data from the CryoSat-2 Sentinel-3 European satellites.

The Northern Adriatic Sea and the area around Venice is a perfect site to test modern altimetry applied to coastal studies in virtue of the favourable location of altimetric tracks as well as the availability of long-term in-situ observations from a number of instruments including tide gauges, wave and wind recorders, that offer clear advantages for comparison purposes.

The aim of this work is the presentation of comparison results of CryoSat-2 and Sentinel-3 data processed with GPOD, in preparation of exploiting HYDROCOASTAL re-processed datasets of sea level, wave amplitude and wind speed in support of regional monitoring.
