Magnetotail total pressure and lobe magnetic field at onsets of sawtooth events and their relation to the solar wind
(American Geophysical Union, 2009-04-01)
Sawtooth events in the Earth's magnetosphere are global, large-amplitude oscillations of energetic plasma particle fluxes at geosynchronous orbit and represent periodic magnetospheric substorms with a typical period of ...
Anomalously low geomagnetic energy inputs during 2008 solar minimum
(American Geophysical Union, 2012-09-01)
The record-low thermospheric density during the last solar minimum has been reported and it has been mainly explained as the consequence of the anomalously low solar extreme ultraviolet (EUV) irradiance. In this study, we ...
Storm time meridional wind perturbations in the equatorial upper thermosphere
(American Geophysical Union, 2013-05-01)
We present observations from the Coupled Ion Neutral Dynamics Investigation (CINDI) of storm time meridional winds in the neutral atmosphere near the magnetic equator at 400km altitude. Observations near the magnetic equator ...
Temporal and spatial dynamics of the regions 1 and 2 Birkeland currents during substorms
(American Geophysical Union, 2013-06-01)
We use current density data from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) to identify the location of maximum region 1 current at all magnetic local times (MLTs). We term this ...
