How to Access Data

Registration Mode: Fast Approval The collection is worldwide available upon approval of the data access request, authorized after successful identity or eligibility check (within 2 days).

The products are available for download via the following interfaces:

ESA EO Multimission Catalogue (EO CAT) Allows users to discover and search products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal, specific). ESA ALOS PALSAR Dissemination Service

The data is collection based and allows data browse and download through the treeview as well as via geographical search using a clickable zoom map. For further information about the EO Sign In Service you can visit TellUs

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