Transpolar voltage and polar cap flux during the substorm cycle and steady convection events [PDF]

open access: yes, 2009
Transpolar voltages observed during traversals of the polar cap by the Defense Meteorological Satellite Program (DMSP) F-13 spacecraft during 2001 are analyzed using the expanding-contracting polar cap model of ionospheric convection.

Initial POLAR MFE observation of substorm signatures in the polar magnetosphere [PDF]

open access: yes, 1997
This paper studies substorm influences in the polar magnetosphere using data from the POLAR magnetic field experiment (MFE). The POLAR spacecraft remains in the high altitude polar magnetosphere for extended periods around apogee.

Space Weather: From solar origins to risks and hazards evolving in time

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Space Weather is the portion of space physics that has a direct effect on humankind. Space Weather is an old branch of space physics that originates back to 1808 with the publication of a paper by the great naturalist Alexander von Humboldt (Von Humboldt,

Posteruptive phenomena in coronal mass ejections and substorms: Indicators of a universal process? [PDF]

open access: yes, 2008
[1] We examine phenomena associated with eruptions in the two different regimes of the solar corona and the terrestrial magnetosphere. We find striking similarities between the speeds of shrinking magnetic field lines in the corona and dipolarization ...

Electron Energization Signatures in Traveling Kinetic Alfvén Waves at Storm Time Injection Fronts

open access: yesGeophysical Research Letters, 2022
The properties of traveling kinetic Alfvén waves (KAWs) and their role in energizing electrons in the inner magnetosphere during a geomagnetic storm are examined using measurements from the Van Allen Probes and Gyrofluid‐Kinetic Electron (GKE) model ...

The effects of particle injections on the ring current development during the 7-8 September 2017 geomagnetic storm

open access: yesFrontiers in Astronomy and Space Sciences, 2023
In this study we investigate the role of particle injections on the ring current development during the 7-8 September 2017 geomagnetic storm by applying a temporally and spatially varying data-driven outer boundary condition in numerical simulations of ...

Relationship Between Relativistic Electron Events Magnetic Storms, and Magnetic Substorms [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
This paper reports a statistical study on the relationship between relativistic electron events(REE), magnetic storms, and substorms. We have used magnetic storm events that occurred between 1996 and 1998, and have classified them into two groups, (i ...

Lessons from a career in space physics

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Frameworks for describing magnetospheric substorms are as good as the data on which they are based. While disturbances in the ionosphere are well described by existing data bases, the plasma and field data acquired by satellites in the magnetosphere are ...
