Welcome to AVISO +
The reference portal in altimetry merging the historical AVISO website from Cnes and the CTOH website. Here, you will find data, articles, news and tools to help you discover or improve your skills in the altimetry domain through four key themes: ocean, coast, hydrology and ice.
Release of the regional XTRACK Tidal Constants product
2020-01-17The XTRACK Tidal Constant is a new added-value coastal altimetry product. It provides accurate along-track tidal constant estimates at regional scale and includes all coastal seas in the world. This product usefully completes tide gauge observations for tidal studies, the validation of tidal models or data assimilation into models.
