Data access





Services



Aviso proposes several ways of accessing data. Some of them need an authentication to get access. If you are not registered and want to access to an authenticated service, we request you to fill in the online form.





New authenticated dissemination services

Since March 26th 2018, the new authentication services are available as described below:

Services	login (=email)/password delivered by Aviso+) (password lost? click here)	specific login/password
My private space "My AVISO+"	click here. For any question, please consult our FAQ
FTP	ftp-access.aviso.altimetry.fr
Thredds Data Server (TDS)	link to the access page
Aviso+ CNES Data Center		https://aviso-data-center.cnes.fr/ Please ask for specific registration directly on the website

Ocean Bulletin
Interface to vizualize Ssalto/Duacs maps for Sea Level Anomalies, Absolute Dynamic Topography, Wind and Waves by  choosing a date and an area. 



Registration form
Register to get access to Aviso product, be informed of all updates, product information and reprocessing


FTP
Aviso FTP is an authenticated FTP. All Ssalto/Duacs product users need an account on FTP, whether for NRT or for DT data, for along-track and gridded products. In NRT, the most recent data are available via FTP.


Aviso+ CNES Data Center
This interface is used by Cnes to archive a wide range of altimetric (including GDRs, SGDRs, etc) and auxiliary data (including Earth rotation parameters, atmospheric correction data...).


Thredds Data Server
The Opendap enables access to remote data sets through familiar data analysis and visualization packages (e.g. Matlab, IDL, Ferret, ncBrowse, Live Access Server), just as if they reside locally on the user's machine. An authentication is required to access it. Get access to the global/regional gridded dataset in NRT (more than one month) and in DT.

Service	Visualization	Download NetCDF	Subscribe to get access	Authenti cated
