alos-2
JAXA L-band SAR satellite. Primary open-data product is the annual global PALSAR-2 mosaic at 25 m GSD (HH + HV). L-band penetrates forest canopy — excellent for above-ground biomass estimation and flood mapping under vegetation. Annual mosaic available free after JAXA AUIG2 registration; non-commercial license caveat. Archive from predecessor ALOS/PALSAR-1 (2006–2011) also available.
