AVISO+: what’s new on the reference portal in satellite altimetry?

AVISO (Archiving, Validation and Interpretation of Oceanographic Satellite data) is a service set up by the French spatial agency, CNES (Centre National d'Etudes Spatiales) to process, archive and distribute data and derived products from satellite missions. Its web portal AVISO+ (www.aviso.altimetry.fr) is the entry point to freely access more than 40 products from CNES and CTOH (Center for Topographic studies of the Ocean and Hydrosphere) not only for ocean-oriented applications but also for hydrology, coastal, biology and sea ice applications. In addition, the website proposes information (handbooks, use cases, outreach material, etc.) to discover the products and their use. New operational (or demonstration) products are regularly added to the AVISO+ catalogue. In 2022, the catalogue has been for instance enriched with several along-track and gridded SSALTO/DUACS experimental products, simulated SWOT Sea Surface Heights, costal products of Sea Level Anomaly (X-TRACK L2P), the Floating Sargassum detection index and climate indicators for the ocean heat content and earth energy imbalance. In 2023, new versions of the models produced by CNES and CLS for the Mean Sea Surface (MSS CNES-CLS 2022) and for the Mean Dynamic Topography (MDT CNES-CLS 2022) will be available for AVISO+ users, as well as the upcoming SWOT oceanographic products. A visualization tool will also be available online to discover the AVISO+ products, including the KaRIn measurements of the SWOT mission over the oceans. An overview of these new AVISO+ products will be presented.
