This program will utilize a combination of two computational techniques to investigate the penetration of high energy particles from the solar wind into the Earth's magnetosphere. Magnetohydrodynamic (MHD) simulations will be used to determine the general interior structure and dynamics of the magnetosphere and a large-scale kinetic (LSK) code will be used to trace test particles to determine where, how, and when energetic particles penetrate the magnetopause and enter the magnetosphere. Particle tracing will then also be used to determine how these energetic particles are transported within the magnetosphere

该方案将利用两种计算技术的组合来研究太阳风高能粒子穿透地球磁层的情况。 磁流体动力学模拟将用于确定磁层的一般内部结构和动态，大尺度动力学代码将用于追踪试验粒子，以确定高能粒子在何处、如何以及何时穿透磁层顶并进入磁层。 然后还将使用粒子追踪来确定这些高能粒子如何在磁层内传输
