The basic structure and dynamics of the primary electric current systems in the Earth's
magnetosphere are presented and discussed. In geophysics, the word current is used to …

One of the definitions of space weather describes it as the time-varying space environment
that may be hazardous to technological systems in space and/or on the ground and/or …

The composition of the inner magnetosphere is of great importance for determining the
plasma pressure and thus the currents and magnetic field configuration. In this study, we …

Solar eruptions cause geomagnetic storms in the near‐Earth environment, creating
spectacular aurorae visible to the human eye and invisible dynamic changes permeating all …

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 …

Based on comprehensive measurements from Helium, Oxygen, Proton, and Electron Mass
Spectrometer Ion Spectrometer, Relativistic Electron‐Proton Telescope, and Radiation Belt …

Oxygen (O+) enhancements in the inner magnetosphere are often observed during
geomagnetically active times, such as geomagnetic storms. In this study, we quantitatively …

Electromagnetic ion cyclotron waves have long been recognized to play a crucial role in the
dynamic loss of ring current protons. While the field‐aligned propagation approximation of …

Deep penetration of energetic electrons (10s–100s of keV) to low L‐shells (L< 4), as an
important source of inner belt electrons, is commonly observed during geomagnetically …

Our investigation of the long‐term ring current proton pressure evolution in Earth's inner
magnetosphere based on Van Allen Probes data shows drastically different behavior of the …
