GEM: Relativistic Electron Losses from the Radiation Belts

这个项目将研究拉伸的磁力线作为辐射带中相对论电子损失的机制的作用。进入电离层的相对论电子沉淀可分为两类，持续不到一秒的短暂微爆发和持续一秒以上的沉淀带。微暴已被广泛研究，但降水带背后的物理机制并未受到太多关注。本项目将侧重于磁力线的伸展对降水带的形成所起的作用。将使用SAMPEX卫星的降水数据统计数据库。为了考察磁力线拉伸的影响，将使用Tsyganenko磁场模型。

This project will investigate the role of stretched magnetic field lines as a mechanism for the loss of relativistic electrons from the radiation belts. Relativistic electron precipitation into the ionosphere can be divided into two categories, brief microbursts lasting for less than a second and precipitation bands lasting for more than a second. Microbursts have been extensively studied, but the physics behind the precipitation bands have not received much attention. This project will focus on the role that the stretching of magnetic field lines has on the creation of the precipitation bands. A statistical database of precipitation data from the SAMPEX satellite will be used. In order to examine the effect of magnetic field line stretching, the Tsyganenko magnetic field models will be used.
