Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'

Investigating the Dependence of Normalized Reconnection Rate on Upstream Plasma Parameters

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We present the results of a multi‐event study of the normalized reconnection rate integrating events spanning the three primary regimes of reconnection observed by the Magnetospheric Multiscale mission. We utilize a new method for determining the normalized reconnection rate with fewer sources of uncertainty by estimating the aspect ratio and ...

Exploring Magnetic Reconnection in the Collisional Ionosphere of Mars With MAVEN

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Magnetic reconnection in collisional plasmas has been widely studied in solar and laboratory plasma disciplines, but in situ measurements in space plasmas have rarely been utilized to explore this reconnection regime. Here we study collisional effects on magnetic reconnection in the Martian ionosphere by analyzing in situ data obtained by the ...

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.
