Tropical forests are often under cloud, which hides clearing from ordinary cameras. JAXA's ALOS-4 "DAICHI-4", launched July 1, 2024, carries the L-band PALSAR-3 radar, which sees through clouds and widens the observation swath from 50 km to 200 km at high resolution. Its predecessor's data already powers JAXA's JJ-FAST system, which detects deforestation of a few hectares in 77 countries.
