S P Moraes-Santos et al.
This study investigates the Brazilian low-latitude ionospheric response to CIR/HSS-driven geomagnetic storms during the declining phase of solar cycle 24, from 2016 to 2017. In this period the geomagnetic storms were mostly moderate, SymHmi...
Super-Intense Geomagnetic Storm on 10-11 May 2024: Possible Mechanisms and Impacts [0.03%]
2024年5月10-11日超强地磁暴的可能机制及影响
S Tulasi Ram,B Veenadhari,A P Dimri et al.
S Tulasi Ram et al.
One of the most intense geomagnetic storms of recent times occurred on 10-11 May 2024. With a peak negative excursion of Sym-H below -500 nT, this storm is the second largest of the space era. Solar wind energy transferred through radiation...
The Growth and Decay of Intense GNSS Amplitude and Phase Scintillation During Non-Storm Conditions [0.03%]
非 storm 条件下 GNSS 幅值闪烁和相位闪烁的增强与减弱
Mahith Madhanakumar,Andres Spicher,Juha Vierinen et al.
Mahith Madhanakumar et al.
A multi-instrument study is conducted at the dayside polar ionosphere to investigate the spatio-temporal evolution of scintillation in Global Navigation Satellite System (GNSS) signals during non-storm conditions. Bursts of intense amplitud...
Interhemispheric Asymmetry in the High-Latitude Neutral Density Variations During the 13-14 March 2022 Storm [0.03%]
2022年3月13日至14日磁暴期间高纬度中性密度东西差异的半球不对称性研究

Qingyu Zhu et al.
During the second recovery phase of the 13-14 March 2022 storm, intense high-latitude neutral mass density spikes are detected by satellites at ∼500 km in both hemispheres. These density spikes, accurately modeled by the Global Ionospheric...
Evaluation of CME Arrival Prediction Using Ensemble Modeling Based on Heliospheric Imaging Observations [0.03%]
基于日球成像观测的集成模型CME到达预测评估
Tanja Amerstorfer,Jürgen Hinterreiter,Martin A Reiss et al.
Tanja Amerstorfer et al.
In this study, we evaluate a coronal mass ejection (CME) arrival prediction tool that utilizes the wide-angle observations made by STEREO's heliospheric imagers (HI). The unsurpassable advantage of these imagers is the possibility to observ...

Galactic cosmic rays enter Earth's atmosphere after interacting with the geomagnetic field. The primary galactic cosmic rays spectrum is fundamentally changed as it interacts with Earth's atmosphere through nuclear and atomic interactions. ...
Spectral Analysis of the September 2017 Solar Energetic Particle Events [0.03%]
2017年9月太阳高能粒子事件的谱分析研究进展
A Bruno,E R Christian,G A de Nolfo et al.
A Bruno et al.
An interval of exceptional solar activity was registered in early September 2017, late in the decay phase of solar cycle 24, involving the complex Active Region 12673 as it rotated across the western hemisphere with respect to Earth. A larg...
