The terrestrial ring current is an electric current flowing toroidally around the Earth, centered
at the equatorial plane and at altitudes of∼ 10,000–60,000 km. Changes in this current are …

Abstract Space weather effects arise from the dynamic conditions in the Earth's space
environment driven by processes on the Sun. While some effects are influenced neither by …

Local acceleration is required to explain electron flux increases in the outer Van Allen
radiation belt during magnetic storms. Here we show that fast magnetosonic waves …

We study the effect of electromagnetic ion cyclotron (EMIC) wave scattering on radiation belt
electrons during the large geomagnetic storm of 21 October 2001 with minimum Dst=− 187 …

Abstract The Extreme Ultraviolet Imager (EUV) of the IMAGE Mission will study the
distribution of He+ in Earth's plasmasphere by detecting its resonantly-scattered emission at …

Our numerical model of the ring current‐atmosphere coupling (RAM) is further developed in
order to include wave‐particle interaction processes. The model calculates the time …

Fast magnetosonic waves can lead to the local acceleration of electrons from∼ 10 keV up to
a few MeV on a timescale of 1–2 d and may play an important role in radiation belt …

A time‐dependent kinetic model is used to investigate the relative importance of various
mechanisms in the early phase decay rate of the ring current. It is found that, for both the …

Geomagnetic indices are convenient quantities that distill the complicated physics of some
region or aspect of near‐Earth space into a single parameter. Most of the best‐known …

The development of the ring current ions in the inner magnetosphere during the main phase
of a magnetic storm is studied. The temporal and spatial evolution of the ion phase space …
