About AVISO+
AVISO+ is a website that provides satellite oceanography data and tools for studying sea level and related measurements. Its homepage lists sea surface height products, value-added and wind/wave products, ice products, ocean indicator products, and tide gauge products, grouped by topics such as ocean circulation, tides, mean sea level, ENSO, and ice and cryosphere. Data can be reached through a registration form, FTP, and a THREDDS data server. Users can also find product handbooks, data format information, and mission-specific processing and update notes.
The site also offers software for working with the data, including a Basic Radar Altimetry Toolbox, data reading software, a visualization tool, and a pass locator. Recent entries describe open-source Python libraries for SWOT altimetry data, which can be installed through conda-forge. Use of the products is governed by the AVISO licence agreement, and the site asks users to follow its citation terms.
