Integrating Satellite Retrievals, Numerical Models, and Machine Learning for Global Groundwater Recharge Estimation

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Knowledge of the groundwater recharge rate determines whether aquifer use is sustainable. However, accurately measuring recharge globally presents significant challenges due to the complexity of subsurface processes and the lack of direct observational methods.

Soil Moisture Buffers the Impact of Precipitation Variability on Ecosystem Productivity

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Water availability governs ecosystem productivity, yet estimates of vegetation sensitivity to water can differ greatly depending on whether the sensitivity is examined spatially or temporally. In particular, the spatial sensitivity is often reported to be much stronger than temporal sensitivities, leading to highly uncertain projections of ...

Dominance of Ricinus communis in the Semi‐Arid Region Mediated by Allelopathy

Weed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT The introduction of invasive alien species can adversely affect the functioning of natural ecosystems. Ricinus communis L., widely present in the Brazilian semi‐arid region, establishes itself in areas with native species, such as Handroanthus impetiginosus (Mart.

A Modified Hierarchical Vision Transformer for Soil Moisture Retrieval From CYGNSS Data

Water Resources Research
This research introduces a new deep learning (DL) framework, multi‐head self‐attention‐aided vision Transformer (MSA‐ViT), for soil moisture (SM) retrieval using Cyclone Global Navigation Satellite System (CYGNSS) data. We first assess the sensitivity of

Mackenzie River Freshwater Controls Early Sea Ice Formation in the Eastern Beaufort Sea

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Arctic sea ice plays a critical role in Earth's climate system, and as it continues to thin and retreat, understanding the processes driving its variability is increasingly important. Using satellite data and a coupled ocean–sea ice model, we examined how freshwater from the Mackenzie River influences fall sea ice formation in the Beaufort Sea.

Dusty Streets: The Challenge of Dust‐Borne Pollutants in Low‐Income Countries

CLEAN – Soil, Air, Water, Volume 54, Issue 2, February 2026.
Generally, pollution impacts developed and low‐income countries (LICs) to different extents, and the disease burden due to roadway dust is not uniformly distributed across socio‐economic classes. Roadway dust materials from paved and unpaved urban and rural roads were reported to contain organic constituents which are toxic and affect public health ...

Validation Analysis of SMAP and AMSR2 Soil Moisture Products over the United States Using Ground-Based Measurements

Remote Sensing, 2017
Soil moisture products acquired from passive satellite missions have been widely applied in environmental processes. A primary challenge for the use of soil moisture products from passive sensors is their reliability.
