Weak Tropical Tropospheric OH Response to Idealized ENSO

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The hydroxyl radical (OH) is a key oxidant for methane. Previous studies suggest that OH exhibits interannual variability linked to the El Nino–Southern Oscillation (ENSO), but the sign, magnitude, and underlying mechanisms of this response remain uncertain.

Spiky Bursts of Energetic Electron Beams Upstream of Nonstationary Quasi‐Perpendicular Shocks

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Energetic electron beams play a crucial role in collisionless shocks by driving upstream plasma waves and providing seed populations for diffusive shock acceleration. However, the processes responsible for their generation at quasi‐perpendicular shocks remain poorly understood.

Widespread Increase in Global Plant Water Stress Obscured by Greening

open access: yesAGU Advances, Volume 7, Issue 4, August 2026.
Abstract Understanding the vulnerability of plants to more severe and frequent drought events and developing adaptive management strategies requires robust methods for quantifying long‐term changes in plant water stress (PWS). Most data‐driven explorations of long‐term trends in PWS have focused on alterations in canopy structure (e.g., leaf area index)

Can a Persistence‐Based Prediction of GRACE Gravity Field Coefficients Reduce Uncertainties at Finer Temporal Scales?

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Enhancing the applicability of Gravity Recovery and Climate Experiment (GRACE) products poses challenges due to the trade‐off between the temporal and the spatial resolution within limits posed by the mission design. If a Kalman filter framework was adopted to characterize the relationship between monthly and finer temporal scales, it could ...

The Ceiling Height of Wildland Fire Plumes in Quasi‐Steady Stratified and Sheared Boundary Layers

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Radar observations from a prescribed fire experiment reveal a large‐scale, billow‐like vorticity structure associated with the plume head near the onset of plume bending. This bending limits the vertical extent of the plume and defines the characteristic plume ceiling height.

Utilizing NASA's Operation IceBridge Airborne SWE and Precipitation Products to Assess Surface Snow Over Alaskan Glaciers

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...

On the Generation of Pre‐Sunrise Equatorial Plasma Bubbles in Southeast Asia During the Geomagnetic Storm of May 2024

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...
