Interpolating Electron Diffusion Coefficients in Earth's Radiation Belts: A Neural Network Model Inspired by Video Frame Interpolation
1 Introduction The Earth's radiation belts are filled with energetic charged particles trapped by the geomagnetic field. These energetic particles reach a dynamic equilibrium resulting from acceleration, transport and loss processes (Baker et al., 2016; Bortnik & Thorne, 2007; Drozdov et al., 2022; Li et al., 2006; Liu et al., 2022; Ma et al., 2016; Reeves et al., 2003; Tu et al., 2019; Turner et al., 2013; Xiang et al., 2017, 2021; Xiao et al., 2009).
Verifying through involvement: unveiling the potential of anthropomorphism in enhancing users' intentions to verify AI-generated information
ABSTRACT The prevalent use of generative artificial intelligence (AI) in everyday life has caused widespread misinformation. Despite the pressing need for users to verify AI-generated content, factors influencing their intentions to do so have remained underexplored. This study, grounded in the involvement theory, examines how AI anthropomorphism affects users' intentions to verify AI-generated content.
A slot region in the magnetosphere of Jupiter - Nature Communications
Abstract Understanding the balance between charged particle acceleration and loss is central to radiation belt research. Jupiter’s Galilean moons orbit within its intense radiation environment and can act both as sources and sinks of energetic particles. Using observations from the Juno spacecraft, we identify large-scale depletions of energetic electrons along Europa’s orbit. These depletions are too deep to result from direct absorption by the moon alone.
Application of Ensemble Kalman Filter With Covariance Localization in Data Assimilation of Radiation Belt Electrons
1 Introduction Earth's radiation belts consist mainly of high-energy particles trapped by the geomagnetic field. They are typically divided into two regions: the inner and outer belts separated by the slot in between. The inner belt, primarily composed of energetic protons, is located within the L-shell range of ∼1.1–2, while the outer belt, mainly made up of energetic electrons, spans L-shell values from ∼3 to 7 (Baker et al., 2017).
Measurements and Modeling of Electron Precipitation Induced by the Ionospheric Heating Experiment
1 Introduction Various experiments were conducted in the late 1990s to investigate the ionospheric effects due to the transmission of high-frequency waves by ground-based facilities (e.g., Ferraro et al., 1982; Gordon & Carlson, 1974; Hagfors et al., 1983).

Dynamic Responses of Outer Radiation Belt Electron Phase Space Densities to Geomagnetic Storms: A Statistical Analysis Based on Van Allen Probes Observations
1 Introduction The Earth's radiation belts, consisting of energetic (>100 keV) particles, have attracted a great number of scientific attention and interest (Li & Hudson, 2019; Ripoll et al., 2020; Van Allen & Frank, 1959).
Quantifying the Spatiotemporal Evolution of Radiation Belt Electrons Scattered by Lower Band Chorus Waves: An Integrated Model
1 Introduction Since the discovery of the Earth's radiation belt by the Explorer 1 satellite in 1958 (Van Allen & Frank, 1959; Van Allen et al., 1958), the crucial concern in the field of space physics has been to understand and forecast the behavior of energetic electrons in the radiation belts (Baker et al., 1998; Li & Hudson, 2019).
Influences of Solar Wind Parameters on Energetic Electron Fluxes at Geosynchronous Orbit Revealed by the Deep SHAP Method
1 Introduction Hundreds of satellites serving for communication, broadcasting, and navigation operate in the geosynchronous orbit (GEO, with an altitude of ∼36,000 km). These satellites are exposed to a potential hazard environment filled with energetic electrons. The energetic electron fluxes can vary over several orders within a short period during geomagnetic activity times (Baker et al., 1997; Guo et al., 2021, 2023; Shin et al., 2016; Thorne, 2010; Wang et al., 2023; Xiang et al., 2021).

Measurements and Modeling of the Responses of VLF Transmitter Signals to X‐Class Solar Flares at the Great Wall Station in Antarctica
Solar Flare 1: 30 March 2022 Figure 3 shows modeling results of the solar flare event occurred on 30 March 2022. Figure 3a shows GOES XRS measurements of solar X-ray fluxes with wavelengths of 0.1–0.8 nm. This flare event started at 17:21 UT, peaked at 17:37 UT, and ended at 17:46 UT. According to GOES measurements, this event has a maximum flux of 1.3 × 10−4 W/m2 and is labeled as an X1.3 event. Figure 3b shows the energy spectra of solar X-rays as calculated using the FISM2 model.

Resonant Scattering of Radiation Belt Electrons by Off-equatorial Magnetosonic Waves
Fast magnetosonic (MS) waves are commonly regarded as electromagnetic waves that are characteristically confined within ±3o of the geomagnetic equator.
Hot plasma effects on the cyclotron-resonant pitch-angle scattering rates of radiation belt electrons due to EMIC waves
To investigate the hot plasma effects on the cyclotron-resonant interactions between electromagnetic ion cyclotron (EMIC) waves and radiation belt electrons in a realistic magnetospheric environment, calculations of the wave-induced bounce-averaged pitch-angle diffusion coefficients are performed using both the cold and hot plasma dispersion relations.
Bounce resonance scattering of radiation belt electrons by low-frequency hiss: Comparison with cyclotron and Landau resonances
Bounce-resonant interactions with magnetospheric waves have been proposed as important contributing mechanisms for scattering near-equatorially mirroring electrons by violating the second adiabatic invariant associated with the electron bounce motion along a geomagnetic field line. This study demonstrates that low-frequency plasmaspheric hiss with significant wave power below 100 Hz can bounce-resonate efficiently with radiation belt electrons.
Competition between Outer Zone Electron Scattering by Plasmaspheric Hiss and Magnetosonic Waves
We quantify the electron scattering effects of simultaneous plasmaspheric hiss and magnetosonic waves that occurred in two neighboring time intervals but with distinct wave intensity profiles on 21 August 2013. Their combined scattering is found capable of causing electron distribution variations largely distinguishable from the consequences of individual waves.
