Web1 day ago · During storms, the radiation environment around Earth can disappear, and return more intensely in minutes. Here, our goal is to develop new understanding to describe why and how geomagnetic storms are so different, in particular in Earth’s radiation environment the Van Allen Radiation Belts, where much modern technology resides. WebIn this letter, we examine the chain of events illustrated in Figure 1 in order to test which mechanism is primarily responsible for the outer belt relativistic electrons to reach their maximum fluxes during geomagnetic storms. Especially, we will focus on the region at L = 4.5–5.0, which is close to the peak of the radial profile of the maximum fluxes of …
