Mapping of Maximum and Minimum Inundation Extents in the Amazon Basin 2014–2017 with ALOS-2 PALSAR-2 ScanSAR Time-Series Data

open access: yesRemote Sensing, 2020
Seasonal inundation is an important effect that governs the distribution of ecosystems in the tropics. In the Amazon Basin, the seasonal flood pulse causes a difference in high and low water levels that can exceed 15 m.

Monitoring Forest Loss in ALOS/PALSAR Time-Series with Superpixels

open access: yesRemote Sensing, 2019
We present a flexible methodology to identify forest loss in synthetic aperture radar (SAR) L-band ALOS/PALSAR images. Instead of single pixel analysis, we generate spatial segments (i.e., superpixels) based on local image statistics to track homogeneous

Wetland Expansion Reduces CO2‐Equivalent Emissions and Strengthens the Congo Basin's Role as a Net Carbon Sink [PDF]

open access: yesGlobal Change Biology, Volume 32, Issue 2, February 2026.
Congo Basin peat swamp forests are vital carbon sinks, yet climate‐driven shifts in hydrology and wetland greenhouse gas fluxes have not been assessed. Here we quantified changes in swamp forest extents, water table levels, forest productivity and wetland greenhouse gas fluxes between 2007 and 2024.

Application of SAR Interferometry Using ALOS-2 PALSAR-2 Data as Precise Method to Identify Degraded Peatland Areas Related to Forest Fire

open access: yesGeosciences, 2019
Deforestation in peatland areas such as Kalimantan, Indonesia has been going on for decades. The deforestation has indirectly increased peatlands to become degraded and flammable.

Seasonality Analysis of Sentinel-1 and ALOS-2/PALSAR-2 Backscattered Power over Salar de Aguas Calientes Sur, Chile

open access: yesRemote Sensing, 2020
Seasonal changes control the development of salt crust over the Salar de Aguas Calientes Sur located in Andes Highlands, Chile. Precipitations throughout the Altiplanic winter (December to March) and austral winter (June to September) caused ponds to ...

Adaptability Analysis of Sentinel−1A and ALOS/PALSAR−2 in Landslide Detection in the Qinling-Daba Mountains

open access: yesApplied Sciences, 2023
Due to the complex terrain and intense tectonic activity, and harsh climate in the Qinling-Daba Mountains, many landslides occur in the area. Most of these landslides are extremely active, posing a serious threat to the safety and property of local ...
