The three ESA Envisat ASAR Wave Mode collections have been migrated from simple FTPS access to the ESA (A)SAR Online Dissemination Service.

The ASAR Wave Mode data is now made available to users together with all the ERS SAR and Envisat ASAR imagery data.

The (A)SAR Online Dissemination Service is collection based and allows data browsing and download via treeview, filename or advanced catalogue search.

Users can freely browse and search the available products, while an ESA EO Sign In account is needed to download the data. 

For further information about registration to the ESA EO Sign In Service visit TellUs.

Data download is available via HTTPS, including bulk download functionality.

Dismissal of former FTP service

The old ESA FTPS service hosting the same version of the Envisat ASAR Wave collections will be disabled at the end of January 2025. 

User should complete any downloading activities in due time and start using the new service instead.

Envisat ASAR Wave Mode datasets and access information

The ASAR Wave products were processed operationally using the version of the PF-ASAR available at the time of processing and are available in Envisat format.

Information on the ASAR Wave products, related documentation, and how to access the data can be found on the following data description pages:
