This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project will develop an advanced 3-D hybrid simulation code (fluid electrons + kinetic ions) that included the coupling of the magnetosphere to the ionosphere. The hybrid magnetosphere model will be coupled an ionospheric model developed at the Naval Research Laboratory. The existing code (H3D) will be enhanced for petascale application with advanced techniques such as multi-zone asynchronous time-stepping and particle splitting. The resulting code, called H3DM ("M" for multi-zone) will be validated by comparing model results with observational data from a variety of NASA missions.The successful development of a 3-D global, hybrid simulation of the magnetosphere with realistic coupling to the ionosphere has the potential to be transformative in our abilities to model and predict how the solar wind couples to Earth's magnetosphere and ionosphere.The project has societal benefits because of its relevance to space weather and space technology. The project has educational benefits and includes both undergraduates an graduate students in the research.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目将开发一个先进的三维混合模拟代码（流体电子+动力离子），其中包括磁层到电离层的耦合。 混合磁层模型将与海军研究实验室开发的电离层模型耦合。 现有的代码（H3 D）将增强千万亿次的应用与先进的技术，如多区异步时间步进和粒子分裂。 生成的代码称为H3 DM（“M”代表多区域）将通过将模型结果与美国航天局各种飞行任务的观测数据进行比较来加以验证。磁层与电离层真实耦合的混合模拟有可能改变我们对太阳风如何耦合到地球磁层和电离层的建模和预测能力。该项目由于其与空间气象和空间技术的相关性，因此具有社会效益。 该项目具有教育效益，包括本科生和研究生的研究。
