This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project will improve our ability to predict the access of solar energetic protons to Earth's magnetosphere and ionosphere. Solar energetic particle (SEP) events have strong space weather impacts and can change the radiation environment in the radiation belts and can modify the ionosphere. The project will make use of state-of-the-art empirical models of Earth's magnetic field as well as physics-based models of the coupled ionosphere and magnetosphere. The project will compare the different models with ground-based observations to determine the errors incurred by the various assumptions made by the different models. The project will involve research done by undergraduate students.

该奖项由2009年美国复苏和再投资法案（公法111-5）资助。该项目将提高我们预测太阳高能质子进入地球磁层和电离层的能力。 太阳高能粒子（SEP）事件具有强烈的空间天气影响，可以改变辐射带内的辐射环境，改变电离层。 该项目将利用最先进的地球磁场经验模型以及电离层和磁层耦合的物理模型。该项目将把不同的模型与地面观测进行比较，以确定不同模型所作的各种假设造成的误差。 该项目将涉及由本科生完成的研究。
