Evaluating the Operational Application of SMAP for Global Agricultural Drought Monitoring

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
Over the past two decades, remote sensing has made possible the routine global monitoring of surface soil moisture. Regional agricultural drought monitoring is one of the most logical application areas for such monitoring.

Control of Vegetation and Temperature on Topsoil Water Losses

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Due to its location at the interface between land surface and atmosphere, soil moisture (SM) plays an important role in modulating energy, water and carbon fluxes. During periods of decreasing SM, SM loss is dependent on evapotranspiration (ET), drainage and changes in plant water storage. Investigating SM loss can give important insights into

Use of Satellite Soil Moisture to Diagnose Climate Model Representations of European Soil Moisture‐Air Temperature Coupling Strength

Geophysical Research Letters, 2018
Soil moisture‐air temperature coupling (SMTC) strength affects European summer air temperature variability. However, due to a lack of spatially extensive ground‐based soil moisture observations, General Circulation Model predictions of European‐mean SMTC

Assimilating satellite-based soil moisture observations in a land surface model: The effect of spatial resolution

Journal of Hydrology X, 2021
This article focuses on developing a data assimilation system that combines the modeled surface moisture estimates and satellite observations. Specifically, model states simulated by the Noah-MP land surface model are updated using an Ensemble Kalman ...

Fostering Application Opportunites for the NASA Soil Moisture Active Passive (SMAP) Mission [PDF]

, 2010
The NASA Soil Moisture Active Passive (SMAP) Mission will provide global observations of soil moisture and freeze/thaw state from space. We outline how priority applications contributed to the SMAP mission measurement requirements and how the SMAP ...

Depth‐Aware Global Calibration of SM2RAIN‐NWF Using Growing Neural Gas‐Derived Hydroclimatic Clusters Across Heterogeneous Soils

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Accurate rainfall information underpins land‐surface water budgets, extreme‐weather analyses, and climate‐model evaluation. Yet in many regions, rain gauge networks are sparse, making conventional calibration of bottom up rainfall products difficult. To address this, we propose a self calibration framework that removes the need for a dedicated

Tendencies of Soil Microbial NO Emissions During HI‐SCALE as Predicted by a Nitrification/Denitrification Scheme

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Many atmospheric chemical processes, including the formation of secondary organic aerosol (SOA), are strongly modulated by the reactions of NO and NO2NOx ${\text{NO}}_{2}\ \left({\text{NO}}_{x}\right)$. Though NOx ${\text{NO}}_{x}$ is controlled by anthropogenic emissions near urban areas, in rural areas soil microbes can be a significant ...

Modeling soil moisture from rainfall: An evaluation of the diagnostic soil moisture equation

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The diagnostic soil moisture equation (DSME), which estimates soil moisture from antecedent precipitation, can be used to gap‐fill and extend existing in situ records. We train and evaluate the DSME at 157 Soil Climate Analysis Network and 113 US Climate Reference Network (USCRN) stations across the contiguous United States.

Statistical and machine learning for improving the utility of soil moisture networks for satellite‐based soil moisture product assessment in the Upper Missouri River Basin

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Surface soil moisture is essential for understanding energy exchange between land and atmosphere. Mesoscale modeling and remote sensing are two methods that can provide useful surface soil moisture information for helping characterize these exchanges.
