Comparison of ring current proton losses between contributions from scattering by field line curvature and EMIC waves

, 2023
   Although both the field line curvature (FLC) and electromagnetic ion cyclotron (EMIC) waves are recognized to contribute importantly to the loss of energetic protons in the Earth’s ring current, their quantitative differences in scattering ring ...

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

Effects of EMIC wave-driven proton precipitation on the ionosphere

, 2021
This archive contains data files from two simulations of the coupled ring current-ionosphere model (the Ring current Atmosphere interactions Model with Self Consistent magnetic and electric field (RAM-SCBE) and the GLobal airglOW model (GLOW)). These simulations and observations were performed for and used in the paper “Effects of EMIC wave-driven ...

Energy Dependence of Energetic Electron Precipitation Rates Near the Foot of Electron Isotropy Boundary

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We report a rare quiet‐time observation by NOAA‐18 spacecraft flying nearly along the electron isotropy boundary (IBe). Complemented by data from four nearby meridional IBe crossings of other POES spacecraft, this case study provides a novel quantitative information concerning the regular energy dependence of the loss‐cone filling ratio (Jprec/

Generation of Electromagnetic Ion Cyclotron (EMIC)Waves in a Compressed Dayside Magnetosphere

, 2010
Electromagnetic Ion Cyclotron (EMIC) waves are believed to play an important role in the dynamics of energetic particles (both electrons and ions) trapped by the Earths magnetic field causing them to precipitate into the ionosphere via resonant ...

Determining Spatial Scale Size of EMIC Waves

, 2020
Earth’s atmosphere becomes increasingly thin with increasing altitude. Above 100 miles charged particles such as electrons and charged atoms called ions begin to fill the atmosphere. The atmosphere gradually transitions into the thin plasmas that make up

Exploratory Graph Analysis Failed to Reproduce the Hypothesized Functional Zoning Framework in the OECD Survey on Social and Emotional Skills

PsyCh Journal, Volume 15, Issue 3, June 2026.
ABSTRACT The OECD's first Survey on Social and Emotional Skills (SSES) in 2019 assessed 10‐ and 15‐year‐olds across ten cities, employing a framework of 15 skills organized into five dimensions aligned with the Big Five personality traits. While this adult‐derived model offers a parsimonious structure for measuring social–emotional skills, its ...
