Azimuthal plasma pressure gradient in quiet time plasma sheet
[1] We have investigated the quiet-time azimuthal plasma pressure gradient in the plasma sheet at a radial distance of 10 RE to 12 RE using two THEMIS spacecraft that were in overlapping orbits during the 2008 THEMIS tail season. The equatorial plasma pressure is estimated by using the insitu measurement of the plasma pressure and magnetic pressure based on pressure balance assumption. The resu...
متن کاملLocalized fast flow disturbance observed in the plasma sheet
An isolated plasma sheet flow burst took place at 22:02 UT, 1 September 2002, when the Cluster footpoint was located within the area covered by the Magnetometers-Ionospheric Radars-All-sky Cameras Large Experiment (MIRACLE). The event was associated with a clear but weak ionospheric disturbance and took place during a steady southward IMF interval, about 1 h preceding a major substorm onset. Mu...
متن کاملSubstorm inner plasma sheet particle reduction
[1] Geotail measurements from within the equatorial inner plasma sheet at r 10–13 RE are used to show that a reduction in equatorial plasma pressure within the current wedge is a general feature of substorms and that this decrease is simultaneous with the wellknown expansion phase increase in energetic particle fluxes. The decrease in pressure is found to be due to a decrease in particle fluxes...
متن کاملThe statistical studies of the inner boundary of plasma sheet
The penetration of plasma sheet ions into the inner magnetosphere is very important to the inner magnetospheric dynamics since plasma sheet ions are one of the major particle sources of ring current during storm times. However, the direct observations of the inner boundary of the plasma sheet are fairly rare due to the limited number of satellites in near equatorial orbits outside 6.6RE. In thi...
