The ESA (A)SAR On-The-Fly (OTF) data processing and dissemination service allows end-users to gain direct access to the (A)SAR archive from the ERS-1, ERS-2 and Envisat Missions.

The ASAR Wave Mode data is collection based and allows data browsing and download via treeview, filename or geographical catalogue search based on area of interest and metadata.

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

For information on the (A)SAR On-The-Fly service please refer to the OTF User Manual.

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).

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.

The ASAR Wave Mode product is created by inverting the cross-spectra which is computed from inter-look processing of the SLC wave imagettes in order to derive the directional ocean product ocean wave spectra. Auxiliary ADSs included with the product remains the same as for the ASAR Wave Mode Cross-Spectra product (ASA_WVS_1P).

The output follows the format of the Envisat ASAR Level 1B Wave Mode Cross-Spectra Imagette (ASA_WVS_1P) product. This is done in order to be compatible with the ground segment products of Envisat ASAR.

This product provides a continuation of the ERS SAR wave mode data.

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

Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps.
