Marine Heatwave Imprints on Salinity in the Northwest Atlantic

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Marine heatwaves (MHWs) are increasing in frequency and intensity in global boundary current systems such as the Gulf Stream (GS), where ocean circulation regulates upper‐ocean heat and water‐mass properties. We examine temperature–salinity co‐evolution during MHWs in the Northwest (NW) Atlantic using satellite observations and ocean ...

INVESTIGATING THE POSSIBILITY OF PREPARING SMALL SCALE SOIL MOISTURE MAP FROM COUPLED SENTINEL-1 AND SENTINEL-2 DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
With the failure of the radar instrument on NASA's Soil Moisture Active Passive (SMAP) satellite, the Sentinel-1 sensor has been considered as an alternative for replacing the SMAP radar data and restoring the combined radar and radiometer SMC product. A

Uncertainty Quantification of Satellite Soil Moisture Retrieved Precipitation in the Central Tibetan Plateau

Remote Sensing, 2023
SM2RAIN is a well-established methodology for estimating precipitation from satellite or observed soil moisture and it has been applied as a complementary approach to conventional precipitation monitoring methods.

Surface Energy Partitioning Biases in Major Reanalyses Revealed by Soil Moisture Drying Dynamics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Identifying the flux partition regimes between soil moisture (SM) and evaporative fraction (EF, ratio of evapotranspiration to available energy) is important for understanding the hydrometeorological processes as well as the development of Land Surface Models (LSMs).

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

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.

Toward a structured workflow to harmonize soil water content products: A comparative study across different methods

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract This study introduces a structured, multi‐step workflow for harmonizing diverse soil water content (SWC) datasets to improve their meaningful comparability while preserving their intrinsic characteristics. The workflow addresses four components: unit, temporal, vertical, and lateral spatial harmonization, and is applied to point‐scale (PS ...

Streamflow Calibration in Ungauged Basins Using SWOT Discharge and SMAP Surface Soil Moisture Products

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Significant advances have been made in using terrestrial remote sensing to reduce random errors in land surface models (LSMs). However, less progress has been made in dealing with systematic LSM errors that are instead correlated with true system states.

Soil Moisture Active/Passive (SMAP) L-Band Microwave Radiometer Post-Launch Calibration Upgrade [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
The Soil Moisture Active/Passive (SMAP) microwave radiometer is a fully polarimetric L-band radiometer flown on the SMAP satellite in a 6 AM/6 PM sun-synchronous orbit at 685 km altitude. After the SMAP L1B_TB data product version 3 was released in 2016, the radiometer has been undergoing further calibration and validation with the goal of reducing ...
