The project will investigate the role of ULF waves in the energization and diffusion of highly energetic radiation belt particles. It will extend a previously existing two-dimensional model of energetic particles in the Earth's radiation belts to three dimensions, which will allow the model to include effects such as losses of energetic particles to the upper atmosphere. It will couple the model to a more realistic model of the magnetic field and electric field produced by Magnetohydrodynamic modeling of the global magnetosphere.

该项目将研究超低频波在高能辐射带粒子的扩散和扩散中的作用。 它将把以前存在的地球辐射带高能粒子二维模型扩展到三维，使模型能够包括高能粒子损失到高层大气等影响。 它将把该模型与全球磁层的磁流体动力学模型所产生的更现实的磁场和电场模型耦合起来。
