Spatial Heterogeneity and Drivers of Vertical Error in Global DEMs: An Explainable Machine Learning Approach in Complex Subtropical Coastal Zones

Remote Sensing
Digital elevation models (DEMs) are foundational for critical tasks such as flood inundation simulation, disaster risk assessment, and ecosystem monitoring in coastal zones, yet their vertical accuracy is significantly compromised by complex terrain and ...

Physics‐Aware Gated Spatiotemporal Fusion Network for Adaptive Large‐Scale Atmospheric Circulation Guidance in Wind Speed Prediction

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Accurate spatiotemporal wind speed prediction is essential for improving wind energy utilization and ensuring power grid security. However, existing methods often rely on incorporating multiple meteorological variables, which increases model complexity and obscures the role of large‐scale circulation in guiding local wind evolution.

Decadal Erosion Rates and Sediment Buffering Identified Through Enhanced DEM Differencing Using Underutilized Global Satellite DEMs

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.

Multi‐Sensor Spatiotemporal Fusion for 30‐m Daily Gapless Snow Cover Mapping

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract High spatiotemporal resolution remote sensing data is crucial for monitoring heterogeneous mountainous snow cover. Although spatiotemporal fusion presents a promising approach for high‐resolution snow monitoring, cloud contamination and sparse observations remain a critical constraint on its large‐scale and long‐term implementation. To address

DataSheet1_Quantifying Geodetic Mass Balance of the Northern and Southern Patagonian Icefields Since 1976.docx

, 2022
Southern Andean glaciers contribute substantially to global sea-level rise. Unfortunately, mass balance estimates prior to 2000 are limited, hindering our understanding of the evolution of glacier mass changes over time.

Global Hydroclimatic Controls on Multithread River Dynamics

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.
