Comparative study of a substorm event by satellite observation and model simulation

Ridley, A. J.; Wang, Hui; Ma, ShuYing

A substorm event has been simulated for the first time by using SWMF (Space Weather Modeling Framework) developed by the University of Michigan. The model results have been validated using Geotail and Cluster satellite observations. The substorm onset occurs at 22:08 UT on September 28 2004, as identified from FUV WIC observations on the NASA IMAG…

Cluster observations of high-altitude cusp during multiple fast-turning IMF

Pitout, F.; Davies, J. A.; Dunlop, M. W. +3 more

Using coordinated observations from the Cluster, DMSP and ESR radar, high-altitude cusp was investigated for a time period characterized by four fast reversals of the IMF BZ. On February 12, 2003, Cluster was flying sunward at duskside over the Northern Hemisphere, across the high-altitude northern cusp twice. Both the two crossings are during ste…

Statistical survey on the magnetic field in magnetotail current sheets: Cluster observations

Balogh, A.; Lucek, E.; Zhao, Jin Rong +2 more

The distribution properties of the magnetic field in magnetotail current sheets have been explored statistically with the magnetic measurement data of the Cluster mission from June to November of the years 2001-2005. It is found that, on average, the strength of the magnetic field and its Bz component in the current sheet are weaker in the region …
