Updates, Examples and Validation of the Global Ionosphere Thermosphere Model

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study provides an updated description, example simulations, and validation of the Global Ionosphere Thermosphere Model (GITM). The updates to GITM include using an exothermic semi‐implicit chemistry scheme that no longer requires an altitude dependent heating efficiency; an ionospheric wind‐driven dynamo; improved neutral, ion, and ...

Integrating GRACE and InSAR Data to Assess Land Surface Displacement From Managed Aquifer Recharge

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Satellite‐based monitoring of groundwater changes and their surface effects is crucial for understanding hydrological processes and managing water resources in an era of increasing water scarcity. The Gravity Recovery and Climate Experiment follow‐on (GRACE‐FO) mission provides global measurements of terrestrial water storage anomalies, while ...

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Detection and Modeling of Co‐Seismic Ionospheric Disturbances Induced by the 2024 Mw 6.6 Deep‐Focus Earthquake in Brazil

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 20 January 2024, a deep‐focus earthquake (Mw 6.6, depth 607 km) struck near Tarauacá, Brazil, within the subducted South America Nazca Plate. Although it produced no surface damage, the event generated clear co‐seismic ionospheric disturbances (CSIDs) detectable in GNSS‐based Total Electron Content (TEC) data from the Brazilian RBMC network.

Scaling plant hydraulic traits to predict ecosystem fluxes under drought

New Phytologist, Volume 250, Issue 4, Page 2078-2084, May 2026.
Summary Expanding plant hydraulic trait measurements and advances in hydraulic modeling have improved mechanistic predictions of water–carbon fluxes under drought. However, mismatches between individual‐scale traits and ecosystem‐scale model representations introduce prediction uncertainties and obscure how drought impacts propagate across scales. This
