Remotely Sensed High‐Resolution Soil Moisture and Evapotranspiration: Bridging the Gap Between Science and Society

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract This paper reviews the current state of high‐resolution remotely sensed soil moisture (SM) and evapotranspiration (ET) products and modeling, and the coupling relationship between SM and ET. SM downscaling approaches for satellite passive microwave products leverage advances in artificial intelligence and high‐resolution remote sensing using ...

Implications of CMIP6 Models‐Based Climate Biases and Runoff Sensitivity on Runoff Projection Uncertainties Over Central India

International Journal of Climatology, Volume 44, Issue 16, Page 5727-5744, 30 December 2024.
This paper presents a first‐ever assessment of the influence of diverse CMIP6 climate biases and associated runoff sensitivity on regional‐scale runoff projection uncertainty under non‐stationary climate. By employing variance decomposition, the study quantifies the uncertainty contribution of different components in the runoff modelling chain ...

Multi‐Scale Soil Salinization Dynamics From Global to Pore Scale: A Review

Reviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Soil salinization refers to the accumulation of water‐soluble salts in the upper part of the soil profile. Excessive levels of soil salinity affects crop production, soil health, and ecosystem functioning. This phenomenon threatens agriculture, food security, soil stability, and fertility leading to land degradation and loss of essential soil ...

Hydrology on Solid Grounds? Integration Is Key to Closing Knowledge Gaps Concerning Landscape Subsurface Water Storage Dynamics

Hydrological Processes, Volume 38, Issue 11, November 2024.
An increasingly wide and diverse range of observational products of landscape subsurface water storage dynamics is maturing, while new ones are still being added; depicted here from cosmic‐ray neutron sensing (CRNS) to satellite missions such as GRACE‐FO and CYGNSS.
