blue arrow DESCRIPTION

The dataset contains all ESA acquisitions over the ADEN zone (Europe, Africa and the Middle East) plus some worldwide products received from JAXA. 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

blue arrow HOW TO ACCESS THIS DATA

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

Discovery and search with various criteria (area of interest, time window, metadata) are offered through the EO-CAT catalogue.

Data browse and download as well as searches based on area of interest and metadata are available through the TPM VOADS Online dissemination server and SO-CAT. RAW data are immediately available, higher level data (GDH, GEC and SLC) are processed on-the-fly and made available to the users.
