PALSAR Products Information
ALOS-1 PALSAR products are available via the ESA PALSAR data On-The-Fly (OTF) processing and dissemination system.
The service currently provides access from ESA's archive to the following PALSAR L1 high-resolution data products.
Note that there are differences between JAXA and ESA ALOS PALSAR CEOS product formats. The ESA L1.1 is in zero-Doppler and not beam coordinates. The signal data record headers also have a different format - the ESA "L1:1" products are basically identical to L1.5 products, aside from slant range projection/pixel dimensions.
ALOS-1 products follow the standard CEOS format convention. 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.

Products Availability
The PALSAR OTF system provides direct online access to ESA's ALOS-1 PALSAR archive for ESA registered users, without the need to interface with the ESA Order Desk.
Data are accessible through the ALOS PALSAR On-The-Fly web interface
To access ESA missions and ESA Third Party Missions data, you need to create an EO Sign In account.
