4. Download (via HTTPS or FTPS)

The dissemination service provides data generated within the ESA FDR4ALT project.

The data is collection based and allows data browsing and download via treeview, filename or advanced catalogue search.

Data download is available via HTTPS, including bulk download functionality. ESA internal users can use their ESAAD account to access the HTTPS Dissemination Service.

Envisat products can also be discovered through ESA's Exploring Earth service, which allows users to browse and download products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal).

Access to ftps://hm-lbr-ds.eo.esa.int is available via common FTP clients using “implicit FTP over TLS” and your own EO Sign In credentials. For internal ESA users the ESAAD account cannot be used for FTP access.

New users can register an account on EO Sign In. For further information about the EO Sign In Service you can visit TellUs.

Should you need support to access the data, please contact EOHelp.

This is the Ocean Waves Thematic Data Product (TDP) V1 resulting from the ESA FDR4ALT project and containing Significant Wave Height estimates for the ERS-1, ERS-2 and Envisat missions.

Compared to existing datasets, the Ocean Waves TDP demonstrates notable improvements in several aspects:

• Great improvements for Envisat due to noise reduction from Adaptive retracker and High-Frequency Adjustment (HFA)
• All variables are given at 5 Hz

The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used.
Information for expert altimetry users is also available in a dedicated NetCDF group within the products.

Please consult the FDR4ALT Product User Guide before using the data.

The FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.
