On the Importance of the Jacobian of a DNN Observation Operator in Land Data Assimilation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract A recent study (Shan et al., 2024, https://doi.org/10.1016/j.rse.2024.114167) showed that using a Deep‐Neural‐Network (DNN)‐based observation operator in land data assimilation (DA) does not guarantee improvements in surface soil moisture (WG2).

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

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

Fall Soil Moisture Modulates Snow‐Streamflow Dynamics in the Colorado River Basin

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The Colorado River Basin (CRB) has experienced a prolonged drought since 2000, with recent years showing a weakened relationship between snowpack conditions and streamflow. In this study, we examined the roles of fall soil moisture and spring weather on modulating snow‐streamflow dynamics in the CRB and its sub‐basins.

Development of low latency, high resolution SMAP soil moisture retrievals in support of near-real-time applications

Frontiers in Earth Science
Soil moisture plays a crucial role in weather forecasting and climate prediction, and provides useful information for flood and drought monitoring, and agricultural irrigation scheduling. In recent decades, soil moisture measurements have been enabled by

Adaptation and Response in Drylands: A Dryland Research Agenda and Campaign Strategy

Global Change Biology, Volume 32, Issue 7, July 2026.
The Adaptation and Response in Drylands (ARID) campaign was selected by NASA as a scoping study to develop a research agenda for a dryland field campaign. Here, we detail our ARID science research agenda and implementation plan that were developed based on an extensive community engagement effort in over 160 events with over a thousand scientists, land

Dynamics off the Congo River and Its Impact on the Water Exchange Between the Coastal and Open Ocean at Different Timescales

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Congo River represents one of the largest freshwater discharges in the Atlantic Ocean. In this study, we investigate the role of mesoscale and submesoscale dynamics in modulating salinity transport, using a 3 km‐resolution realistic numerical simulation.

A Global, Daily Carbon Budget for Terrestrial Ecosystems Constrained by Satellite Observations of Soil Moisture: The SMAP Level 4 Carbon Product at Ten Years

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The capacity of terrestrial ecosystems to retain carbon or sequester more atmospheric carbon is frequently investigated as a potential natural climate solution. However, global carbon inventories, national carbon assessments, and atmospheric inversion studies suffer from key limitations: infrequent estimates, low spatial resolution, or a lack ...

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,
