Space Weather refers to conditions in the near-Earth space environment that can negatively impact the performance and reliability of technological systems or can endanger human life or health. Significant space weather impacts can be both costly and dangerous. The impacts of space weather include satellite memory errors, phantom commands, loss of communication with deployed troops and aircraft that are over the horizon, significant errors in GPS position determination, and failures of power grids. The development of a reliable space weather forecast capability is a high national priority for both civilian and national security purposes. Overcoming the limited availability of in situ and remote sensing data sources and finding ways to compensate for missing physics even in the most advanced Sun-to-Earth space weather models are fundamental challenges that must be solved to make advances to space weather forecasting models. This project employs computational thinking to carry out transformative research that addresses both of these challenges. It will pioneer new methods for space weather modeling that will be transformational and eventually lead to a reliable space weather forecast capability. The project is highly interdisciplinary and will pursue these important goals in space weather modeling by developing and utilizing frontier image reconstruction ideas from theoretical computer science together with novel adaptive model correction methodologies from control systems engineering. The results of this project will aid in establishing a reliable space weather forecasting capability for the nation. Present methods have very limited reliability beyond now-casting. This project would help achieve approximately 18-hour forecast capability, which would constitute a tremendous advance. Through collaboration with the NASA/NSF Community Coordinated Modeling Center the project will enable validation and transfer of the resulting knowledge, systems and tools to real space weather operations. Computer codes, algorithms, and tools will also be made freely available to other researchers, allowing the broader research community to utilize the tools that are developed for their own research needs. Four graduate students will be employed and trained under this project. In addition, the research results will be incorporated in undergraduate and graduate curricula at University of Michigan. The project will also strengthen and expand an ongoing collaboration with a local children's museum by creating exhibits about space exploration and space weather.

空间气象是指近地空间环境中可能对技术系统的性能和可靠性产生负面影响或可能危及人类生命或健康的条件。重大的空间气象影响可能既昂贵又危险。空间天气的影响包括卫星存储器错误、幻影命令、与部署的部队和飞机失去通信、GPS定位的重大错误以及电网故障。发展可靠的空间气象预报能力是国家民用和国家安全的高度优先事项。克服现场和遥感数据源的有限可用性，并设法弥补即使在最先进的日地空间气象模型中缺失的物理学，是推进空间气象预报模型必须解决的根本性挑战。 该项目采用计算思维来进行变革性研究，以解决这两个挑战。它将开创空间气象建模的新方法，这些方法将是变革性的，并最终导致可靠的空间气象预报能力。 该项目具有高度的跨学科性，将通过开发和利用来自理论计算机科学的前沿图像重建思想以及来自控制系统工程的新型自适应模型校正方法来实现空间气象建模中的这些重要目标。 该项目的成果将有助于为国家建立可靠的空间气象预报能力。目前的方法在即时预报之外的可靠性非常有限。 这一项目将有助于实现大约18小时的预报能力，这将是一个巨大的进步。 通过与美国航天局/国家科学基金会社区协调建模中心合作，该项目将能够验证所产生的知识、系统和工具，并将其转移到真实的空间气象业务中。 计算机代码、算法和工具也将免费提供给其他研究人员，使更广泛的研究界能够利用为自己的研究需要开发的工具。 四名研究生将在该项目下就业和培训。此外，研究成果将纳入密歇根大学的本科和研究生课程。 该项目还将通过举办有关空间探索和空间气象的展览，加强和扩大与当地儿童博物馆正在进行的合作。
