We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

ALOS PALSAR RTC Project
ASF’s Radiometric Terrain Correction Project
RTC removes the geometric and radiometric distortions inherent in synthetic aperture radar (SAR) and the corrected PALSAR data are provided in a GIS-compatible GeoTIFF format. The release of ALOS PALSAR RTC products commenced in October 2014 and was completed a year later. Data used in the RTC project were Fine Beam (FBS, FBD) and Polarimetric (PLR) scenes over all global land areas except Antarctica, Greenland, Iceland, and northern Eurasia.
