AGU's Scientific Legacy

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The AGU community is a resource for insights into how past research has influenced today's science and will continue to inform the Earth and Space sciences of the future. To capture the voices and opinions from this community, three interviews were held at the 2024 AGU Meeting and broadcast on AGUTV.

Energetic Ion Losses Observed During Juno's Close Encounter With Europa

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract We present energetic ion observations made by Juno during its close Europa flyby on 29 September 2022. These data show significant reductions in the ion intensities occurring in the moon's geometric wake region. The most significant losses occur for locally mirroring ions with gyrophases on the anti‐Jovian facing side of the wake.

Flux Tube Properties and Interchange Instabilities in Jupiter's Middle Magnetosphere

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract In Jupiter's magnetosphere, the outward transport of Io‐genic plasma and the planetward injection of energetic particles are facilitated by flux tube interchange motion driven by centrifugal instabilities. Flux tube content and entropy are two competing key quantities that determine the behavior of the system.

Plasmaspheric‐Origin Ions as a Major Source of Plasma Sheet Pressure During Storm Early Main Phase

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract The plasmasphere and plasma sheet are physically distinct but dynamically connected through global magnetospheric processes. Using a multifluid magnetohydrodynamic model including solar wind, ionospheric, and plasmaspheric H+ and O+ components, coupled with ring current and polar wind models, we simulate the 8 September 2017 storm. The modeled

Significant Amplification of Turbulent Energy Dissipation Through the Shock Transition at Mars

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Turbulence is fundamental to energy transfer across scales in space and astrophysical plasmas. Bow shock interactions have long been hypothesized to significantly modify turbulence in planetary environments, yet the quantification of such effects and their parametric dependencies remain largely unaddressed.

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.

Uncertainty‐Aware Machine Learning Bias Correction and Filtering for OCO‐2. 2

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Quality filtering of satellite XCO2 retrievals is essential for every downstream science application, yet the community still grapples with the trade‐off between retaining data availability and suppressing biases. For the Orbiting Carbon Observatory‐2 (OCO‐2) record in particular, the long‐standing binary quality flag targets the single use ...

Evidence for Caribbean Plate Subduction Beneath the Isthmus of Panama and Implications for Subduction Initiation and the Closure of the Central American Isthmus During the Miocene

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The evolution of the Isthmus of Panama during the Miocene resulted in climatic shifts leading to global cooling, reorganization of ocean currents, and regional mass extinctions. The causes of this change in ocean circulation between ∼15 and 5 Ma have been debated, with various tectonic scenarios being proposed as explanations for this event ...

Quantifying the Influence of Fault Geometry via Mesh Morphing With Applications to Earthquake Dynamic Rupture and Thermal Models of Subduction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Subsurface geometries, such as faults and subducting slab interfaces, are often poorly constrained, yet they exert first‐order control on key geophysical processes, including subduction zone thermal structure and earthquake rupture dynamics.
