Accurate Spectral Fitting in the Upper F‐Region Using the Randomly Coded Data of the Arecibo 430 MHz Radar

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Accurately resolving the ion composition in the upper F2 region and topside ionosphere remains a challenge due to temperature‐composition ambiguity and measurement limitations. This study presents a hybrid fitting algorithm that combines exhaustive dictionary search with gradient descent to improve the estimation of incoherent scatter spectrum

Enhanced Radiation at Aviation Altitudes and Plasmaspheric Hiss Waves—A Time Shift Analysis

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Increased radiation levels in Earth's atmosphere can present significant risks to airline pilots, passengers, and commercial space travelers. Recent findings have revealed a strong statistical link between radiation dose rates detected at aviation altitudes (>9 ${ >} 9$km) and plasmaspheric hiss wave power observed along the same magnetic ...

A Specification Model of Saturn's Plasma Environment

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present the first empirical‐based specification model of Saturn's plasma environment based on the analysis of all publicly available plasma moment data sets derived using multiple techniques from Cassini observations made by the Cassini Plasma Spectrometer and the Radio and Plasma Wave Science instrument.

A Global Map of Average Electron Densities in the Magnetosphere of Saturn

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Measurements from the Cassini Radio and Plasma Wave Science (RPWS) experiment obtained during the entire orbital phase of the Cassini mission around Saturn (13.2 years) are processed into a meridional map of plasma densities, comprising the innermost region of the ring ionosphere, the Enceladus plasma torus, and the outer magnetosphere, up to ...

Searching for Universality of Turbulence in the Earth's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Turbulence in space plasmas remains a fundamental challenge, and Earth's magnetosphere (MSP) offers a natural laboratory for its study. Using high‐resolution magnetic field data from the Magnetospheric Multiscale (MMS) mission, we extend a stochastic Markovian framework to analyze turbulence across 10 diverse magnetospheric regions, including ...

Determining the Axial Orientations of a Large Number of Flux Transfer Events Sequentially Observed by Cluster during a High-Latitude Magnetopause Crossing

Atmosphere
Flux transfer events (FTEs) are magnetic structures generally believed to originate from time-varying magnetic reconnection at the Earth’s magnetopause.

Occurrence Rates and Variability of Whistler‐Mode Waves in the Plasma Trough

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Numerical models of energetic electron behavior in the outer radiation belt require descriptions of the wave‐particle interactions across the inner magnetosphere. Quasilinear diffusion coefficients describe gyro‐resonant wave‐particle interactions over large time‐ and length‐scales but these must be constrained by observations to construct ...
