Uncovering Responses of the Amazon Fluvial Lake System to the 2024 Drought by Fusing SWOT and Sentinel‐1 Observations

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract The 2024 Amazonian drought presented an unprecedented hydroclimatic anomaly. While prior research focused on atmospheric drivers and river impacts, the response of Amazon fluvial lake system (AFLs) has lacked large‐scale quantification. This study investigates the hydrological response of 838 fluvial lakes to the 2024 drought by integrating ...

Erupted Volume During the 2014–2023 Semisopochnoi Unrest and Eruption Constrained by Multi‐Platform InSAR and Volcanic Gas Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Volcano deformation data provide important constraints on magma dynamics during volcanic unrest and eruptions. From these observations, we can estimate subsurface pressure changes and relate them to volume change in the reservoir. However, because magma and rock are compressible, this volume change cannot be directly equated with eruptive ...

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...

Diffusion‐Based Reconstruction of Western North Pacific Surface Winds From CYGNSS for Tropical Cyclone Analysis

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion

Carbon Accumulation in Tropical Dry Forests and Savannas Despite Widespread Land‐Cover Change, Revealed by Radar Remote Sensing

Global Change Biology, Volume 32, Issue 10, October 2026.
We map aboveground carbon density (AGCD) across tropical dry forests and savannas at 100 m for 2015–2024 using ALOS‑2 L‑band radar calibrated with field plots. Aboveground carbon (AGC) stocks total 25.3 ± 2 PgC (13% of global AGC) and net AGC is increasing at 0.43 ± 0.07 PgC yr−1 (20% of the land sink).
