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 data is collection based and allows data browse and download through the treeview as well as via geographical catalogue search based on area of interest and metadata. Interferometric search option is available for relevant collections. Data download is available via HTTPS, including bulk download functionality.

ERS  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).

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

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

For internal ESA users the ESAAD account cannot be used.

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

The SAR SLC product is a single look complex acquired in Image Mode. It is a digital image, with slant range and phase preserved, generated from raw SAR data using up-to-date auxiliary parameters. The products are intended for use in SAR quality assessment, calibration and interferometric applications. A minimum number of corrections and interpolations are performed on the data. Absolute calibration parameters (when available) are provided in the product annotation.
