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.

The table summarises the ALOS PALSAR offer.
