In Part 2 the system will be expanded to include a far wider set of models of the solar corona the interplanetary medium the Earth s magnetosphere plasmasphere
radiation belts ionosphere and thermosphere.
Another scenario is that the giant cloud of cold, electrically charged gas called the plasmasphere
, which begins about 600 miles above Earth and stretches thousands of miles into the outer Van Allen belt, is scattering the electrons at the boundary with low frequency, electromagnetic waves that create a plasmapheric "hiss," said Baker.
The report said that for the first time in human history, a telescope will also be set up on the moon to observe the plasmasphere
over the Earth and survey the moon surface through radar.
Discoveries: plasmaspheric shoulders and notches, proton auroras in unexpected places, surprisingly slow plasmasphere
rotation, a hot oxygen geocorona and a secondary interstellar neutral atom stream.
Another IMAGE device has taken the first global picture of the electrically charged layer, called the plasmasphere
, that extends into space from Earth's upper atmosphere.
Goldstein, 35, is a space physicist specializing in the structure and dynamics of the Earth's plasmasphere
TOPCAT, a project from the University of Bath, will be the first GPS device aimed at measuring space weather conditions in the plasmasphere
(the areas of space just beyond the eartha s atmosphere).
By analysing data from the European Space Agency's Cluster spacecraft, researcher Iannis Dandouras detected this plasmaspheric wind, so-called because it contributes to the loss of material from the plasmasphere
, a donut-shaped region extending above the Earth's atmosphere.
Coupled with the high energy of the solar wind, the Earth's atmosphere trapped in the magnetic field creates an enormous, 7000 (Degree)C, multimillion-ampere electrically-charged gas cloud surrounding the Earth, called the plasmasphere
By performing a "quantitative treatment of the scattering of relativistic electrons by electromagnetic whistler-mode waves inside the dense plasmasphere
," the investigators were able to account for the "distinctively slow decay of the injected relativistic electron flux" and demonstrate why this unusual third radiation belt is observed only at energies above 2 mega-electron-volts.
is a plasma cloud surrounding Earth above the ionosphere.
Extrapolating this mechanism to the terrestrial magnetosphere, Kronberg and colleagues propose that under certain conditions, periodic magnetospheric substorms at Earth may be driven internally by plasma eroded from the plasmasphere
, a region of Earth's magnetosphere.
