Abstract

The tremendous potential of ALOS-4/PALSAR-3 for further advancements in forest monitoring from local to global scales are discussed on the basis of the groundbreaking achievements made by its predecessor ALOS-2/PALSAR-2, the first long-term L-band SAR forest observation mission in history. The unprecedented seamless and frequent dual-polarization observation of the entire tropical forest belt between 2016 and 2022 has revolutionized the idea of global forest monitoring. In the upcoming ALOS-4 era, wide-area imaging with greatly improved spatial resolution and image quality at shorter revisit times will further boost the reliability for all kinds of forest remote sensing applications including forest classification, biomass estimation and deforestation detection.
