Abstract Using the Cluster/Composition and Distribution Function (CODIF) analyzer data set
from 2001 to 2013, a full solar cycle, we determine the ion distributions for H+, He+, and O+ …

Magnetospheric ions have the potential to affect magnetic reconnection at the
magnetopause. The results of a survey of magnetospheric ions near the magnetopause are …

The two full precessions in local time completed by the Van Allen Probes enable global
specification of the near‐equatorial inner magnetosphere plasma environment …

Ionospheric heavy ions play an important role in the dynamics of Earth's magnetosphere.
The greater mass and gyroradius of ionospheric oxygen differentiates its behavior from …

Abstract On 17 March 2013, the Van Allen Probes measured the H+ and O+ fluxes of the
ring current during a large geomagnetic storm. Detailed examination of the pressure buildup …

We present cross‐scale magnetospheric observations of the 17 March 2015 (St. Patrick's
Day) storm, by Time History of Events and Macroscale Interactions during Substorms …

We present a statistical study of nose‐like structures observed in energetic hydrogen,
helium, and oxygen ions near the inner edge of the plasma sheet. Nose structures are …

We investigate the spatial distributions and composition of contributing energies, which we
term an energy range that makes the dominant contribution to energy density, in the inner …

Ground and space-based observations of the geomagnetic field are usually a superposition
of different sources from the Earth's core, lithosphere, ocean, ionosphere, and …

This study presents observations of the large‐scale electric field and H+ fluxes over the
entire Van Allen Probes mission duration. These observations are used to determine the …
