Influx of Bay of Bengal Waters and Stirring Trends in the Arabian Sea Based on Satellite Altimetry

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Freshwater transport and stirring affect air–sea interactions in the Arabian Sea (AS). Using three decades of satellite‐based surface currents, this study examines (a) the volume influx of water masses into southeastern AS from the Bay of Bengal (BoB), and (b) horizontal stirring over seasonal to interannual timescales in the AS.

Improving Air Quality Simulations in California's San Joaquin Valley Using Land Surface Remote Sensing

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Accurate regional air quality modeling is crucial for the development of effective air pollution mitigation plans. Precisely simulating meteorological conditions, especially planetary boundary layer (PBL) properties, is challenging due to complex land surface conditions.

Evaluation of the Bayesian Downscaling Algorithm for Achieving Higher Resolution Soil Moisture Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The NASA-launched Soil Moisture Active Passive satellite mission (SMAP) had the objective to globally characterize soil moisture with an intermediate resolution (9 km), through the integration of radar (3 km) and radiometer (36 km) observations. The SMAP

Environmental factors influencing detection of ring‐necked pheasant broods during August roadside surveys

The Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We evaluated the influence of environmental factors on detection probability of ring‐necked pheasant broods surveyed during roadside surveys across 11 states. Wind speed, cloud cover, morning dew conditions, and soil moisture influenced detection probabilities and should be the focus of methodological or statistical control in future landscape‐scale ...

Capturing Mesoscale and Submesoscale Ocean Fronts in the Gulf of Mexico With Gaussian Mixture Modeling and Satellite Observations

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract This study advances the detection of ocean fronts in the Gulf of Mexico (GoM) by comparing traditional front detection algorithms with a machine learning model. Specifically, we evaluate the performance of three widely used methods, Canny Edge Detection (referred to as Canny), the Cayula‐Cornillon Algorithm (CCA) (referred to as CCA), and the ...

Rapid Flood Progress Monitoring in Cropland with NASA SMAP

Remote Sensing, 2019
Research in different agricultural sectors, including in crop loss estimation during flood and yield estimation, substantially rely on inundation information. Spaceborne remote sensing has widely been used in the mapping and monitoring of floods. However,

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

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 ...
