ALOS PALSAR
To download PALSAR data from the Alaska Satellite Facility L1 Data Pool of PALSAR data files you must sign up with ASF. See the Alaska Satellite Facility ALOS Data Agreement. To order ALOS PALSAR data from JAXA for archiving at ASF, see ALOS orders.

UNAVCO does not archive ALOS data as part of GeoEarthscope, and does not use or maintain ASF user accounts. As a convenience to SAR data users, UNAVCO does provide the WInSAR Search Tool, including the ALOS PALSAR data files in the ASF L1 Data Pool.
