Plasmapause Position And Proton Density Obtained In The Plasmasphere
Plasmapause Position And Proton Density Obtained In The Plasmasphere The plasmapause position (in pink) and proton density obtained with the model in the plasmasphere during halloween’s event on 31 october 2003. figure 1: plasmapause position and proton density obtained in the plasmasphere during halloween’s event on 31 october 2003. To predict the plasmapause position, we analyze 7 years of van allen probes data to find the plasma density in two different ways, using both the 100 cm −3 density and the density gradient. we look at how their locations change with the level of geomagnetic storm activity and deduce new plasmasphere boundaries models for space weather codes.
Plasmapause Black Circles And Electron Number Density Color Scale We investigated the structure and dynamics of the plasmapause using electron density data from the arase (erg) satellite between 2017 and 2019. by fitting the electron density profile to a hyperbolic function using the least squares method, 1,891 plasmapause events were identified. the hyperbolic function’s fitting parameters were used to. In the inner magnetosphere, the steep plasmapause boundary separates the cold dense plasmasphere, which corotates with the planet, from the hot ring current plasma sheet outside. Density within the plasmasphere and plasmatrough falls off with radial distance as r −4, the inner boundary of the plasmapause is at 4.5 r e and the plasmapause width is 0.2 r e. a similar l dependence in mass density was observed by chi et al. (2013) , while equatorial electron densities exhibit an l −3.07 dependence ( ozhogin et al. 2012 ). The code calculates the positions of the plasmapause versus mlt every hour ut during that given day using the successive values of kp. 3. example of simulations [37] an example of the plasmaspheric density obtained in the geomagnetic equatorial plane with the kinetic model on 8 june 2001 is illustrated on figure 4a. this date has been chosen.

The plasmapause is a highly dynamic boundary between different magnetospheric particle populations and convection regimes. some of the most important space weather processes involve wave particle interactions in this region, but wave properties may also be used to remote sense the plasmasphere and plasmapause, contributing to plasmasphere models. The plasmapause position at the selected instants (0, 1, 2, 6, 10 h) in the equatorial plane r lt after a sudden increase in the dawn dusk electric field from 0.28 to 0.58 mv m 1 [grebowsky, 1970].
