All ALOS-1 products are freely accessible in accordance with ESA’s Earth observation data policy. An active EO Sign In account is required to download the products.

In the ALOS PALSAR Online Dissemination Service and catalogue the data is collection based and allows data browse and download through the treeview and offers an interactive map for identifying available products.

ALOS products can also be discovered through ESA's EO Catalogue (EO CAT), 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.

Description

The dataset contains all ESA acquisitions over the ADEN zone (Europe, Africa and the Middle East) plus some products received from JAXA over areas of interest around the world. Further information on ADEN zones can be found in this technical note.

ALOS PALSAR products are available in following modes:

  • Fine Beam Single polarisation (FBS), single polarisation (HH or VV), swath 40-70 km, resolution 10 m, temporal coverage from 02/05/2006 to 30/03/2011
  • Fine Beam Double polarisation (FBD), double polarisation (HH/HV or VV/VH), swath 40-70 km, resolution 10 m, temporal coverage from 02/05/2006 to 30/03/2011
  • Polarimetry mode (PLR), with four polarisations simultaneously: swath 30 km, resolution 30 m, temporal coverage from 26/08/2006 to 14/04/2011
  • ScanSAR Burst mode 1 (WB1), single polarisation: swath 250-350 km, resolution 100 m, temporal coverage from 12/06/2006 to 21/04/2011.

Following processing levels are available:

  • RAW (Level 1.0): Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene
  • SLC (Level 1.1): Slant range single look complex product. Not available for WB1
  • GDH (Level 1.5): Ground range Detected, Normal resolution product
  • GEC (Level 1.5): Geocoded product.

The table summarises the ALOS PALSAR offer.
