Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth.
Understanding the ionosphere high in the Earth’s atmosphere is important due to its effects on communications systems, satellites and crucial chemical features including the ozone layer. New insights into the activity of high energy electrons have come from a simulation study led by geophysicist Yuto Katoh at Tohoku University, reported in the journal Earth, Planets and Space.
“Our results clarify the unexpected role of the geomagnetic field surrounding the Earth in protecting the atmosphere from high energy electrons,” says Katoh.
The ionosphere is a wide region between roughly 6...
