Comparison of Cryosat-2 and Sentinel-3 Altimetry with in situ measurements of Sea Level, Significant Wave Height and Wind Speed in the Northern Adriatic and around Venice

摘要: 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 …
