Soft Proton Environment Modeling for SMILE Using XGBoost and Solar Cycle–Informed Synthetic Data Sets

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Soft proton contamination presents a persistent threat to the performance of space‐based X‐ray observatories such as ESA's upcoming Solar‐wind Magnetosphere Ionosphere Link Explorer (SMILE). This study develops a machine‐learning framework for modeling soft proton fluxes in the 92.2–159.7 keV range, tailored to SMILE's elliptical, highly ...

Geoeffectiveness of Magnetosheath Jets

, 2019
In this report we present spacecraft and ground-based observations of magnetosheath jets impacting the magnetosphere, both as a case study and a statistical study. In the case study, jets were detected in the magnetosheath by the Magnetospheric MultiScale mission, MMS.

Contrasting Space Weather Drivers of Two Geomagnetically Induced Current Events in Alberta, Canada During the May 2024 Superstorm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Strong geomagnetic disturbances (GMDs) caused by intense space storms induce geomagnetically induced currents (GICs) in the Earth and within long conductive infrastructure, potentially posing risks to electricity transmission systems. Here, we investigate the solar wind conditions and magnetospheric processes responsible for two significant ...

Spatial distribution of plasma density and magnetic field amplitude in the dayside magnetosheath as a function of the IMF orientation

Frontiers in Astronomy and Space Sciences
The properties of the magnetosheath are of pivotal importance in determining the coupling between the magnetosphere and interplanetary medium. In particular, the magnetic flux pileup and plasma depletion layer (PDL) modify the boundary conditions of ...

Experimental and numerical investigation of plasma parameters in the magnetosheath

MATEC Web of Conferences, 2018
We investigate the behaviour of the plasma parameters in the magnetosheath in a case when Interball-1 satellite stayed in the magnetosheath, crossing the tail magnetopause.

Thick escaping magnetospheric ion layer in magnetopause reconnection with MMS observations

Geophysical Research Letters, 2016
The structure of asymmetric magnetopause reconnection is explored with multiple point and high‐time‐resolution ion velocity distribution observations from the Magnetospheric Multiscale mission.

Kinetic evidence of magnetic reconnection due to Kelvin‐Helmholtz waves

Geophysical Research Letters, 2016
The Kelvin‐Helmholtz (KH) instability at the Earth's magnetopause is predominantly excited during northward interplanetary magnetic field (IMF). Magnetic reconnection due to KH waves has been suggested as one of the mechanisms to transfer solar wind ...

A case study of the plasma in the magneto-sheath using the numerical magnetosheath-magnetosphere model and THEMIS measure-ments

MATEC Web of Conferences, 2018
This paper presents a case study of the plasma parameters in the magnetosheath, based on THEMIS measurements. As a theoretical tool we apply the self-consistent magnetosheath-magnetosphere model.

Anisotropy of the Spectral Index in Ion Scale Compressible Turbulence: MMS Observations in the Magnetosheath

Frontiers in Physics, 2019
Turbulence in the Earth's magnetosheath at ion kinetic scales is investigated with the Magnetospheric MultiScale (MMS) spacecraft. The multi-point measurements allow the three dimensional power spectra in wave-vector space to be determined.

Evolution of Turbulence in the Kelvin–Helmholtz Instability in the Terrestrial Magnetopause

Atmosphere, 2019
The dynamics occurring at the terrestrial magnetopause are investigated by using Geotail and THEMIS spacecraft data of magnetopause crossings during ongoing Kelvin−Helmholtz instability.
