ERS-1/2 SAR IM L0 [SAR_IM__0P]

ERS-1/2 SAR Raw Image Product Level 0

How to Access Data

Data is available on the ESA Online Dissemination System upon Request Evaluation

The process usually takes up to two weeks and there are no deadlines for submitting a service request.

The products are available for download via the following interfaces:

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.

For information on the (A)SAR On-The-Fly service please refer to the OTF FAQ page

This SAR Level 0 product is acquired in Image Mode. The products consist of the SAR telemetry data and are supplied as standard scenes. It also contains all the required auxiliary data necessary for data processing.

The product serves two main purposes:

  • For testing ERS SAR processors independently from the HDDR system
  • For users interested in full SAR data processing.

Product characteristics:

  • Scene area: 100 km (range - across track) x full segment length (azimuth - along track)
  • Scene size: 5616 samples (range) x full segment length (azimuth)
  • Pixel depth: 10 bits signed integer (5 bits I, 5 bits Q)
  • Projection: Slant range
