Collaborative Research: SHINE--Automated System for Observation-Based Real-Time Simulation of the Solar Corona and Inner Heliosphere at the Community Coordinated Modeling Center

研究人员将在社区协调建模中心（CCMC）开发一个自动化系统，用于持续运行基于研究、观测驱动的太阳日冕和内日球层实时模拟。每天，或者更频繁地，系统将自动重新启动一个新的模拟太阳日冕的状态，使用最新的太阳磁图作为输入，之前的模拟结果作为新模拟的初始条件。预测整个日冕和内日球层的行星际磁场和太阳风参数的真实三维分布和随时间变化的分布是空间物理学中最具挑战性的科学问题之一。如果将最新的磁图数据作为模型的输入，并使用连续的观测数据流来验证模型，那么每天常规地进行实时模拟，任务就会变得更加困难。这项工作将使用CCMC已经提供的空间天气模拟框架（SWMF）太阳日冕模型。为了验证该模型，将生成合成的极紫外图像，与NASA卫星仪器观测到的图像进行比较。结合ACE卫星实测的太阳风参数，对耦合模式预测进行持续验证。这项研究的智力价值在于开发了一个基于研究的模型，可以用来更好地理解日冕物质抛射（CME）的传播，既可以实时地在日冕图像中观察到CME特征，也可以用于历史分析和有趣事件的研究。该项目的更广泛的影响是，新一代太阳-日球层系统的全球模型将被交付给CCMC，使太阳-日物理社区能够广泛使用。该项目将包括培训一名初级女性博士后研究员，并将加强研究和教育的基础设施。

The investigators will develop an automated system for continuously running a research-based, observation-driven, real-time simulation of the solar corona and inner heliosphere at the Community Coordinated Modeling Center (CCMC). Every day, or more frequently, the system will automatically restart a new simulation of the state of the solar corona using the latest solar magnetogram as the input and the result of the previous simulation as the initial condition for the new one. A prediction of the realistic three-dimensional (3D) and time-dependent distributions of the interplanetary magnetic field and solar wind parameters throughout the solar corona and inner heliosphere is one of the most challenging scientific problems in space physics. The task becomes even more difficult if the simulation is routinely performed in real-time, on a daily basis, with the latest magnetogram data incorporated as an input for the model together with the capability to validate the model using a continuous flow of observational data. The Space Weather Modeling Framework (SWMF) model of the solar corona, already available in the CCMC, will be used for the effort. To validate the model, synthetic extreme ultraviolet images will be produced to compare with the images as observed with NASA satellite instruments. The coupled model prediction will be continuously validated with the solar wind parameters measured by the ACE satellite. The intellectual merit of the research is the development of a research-based model that can be used to better understand the propagation of Coronal Mass Ejections (CMEs), both in real-time when CME signatures are observed in coronograph images, and for historical analysis and research of interesting events. The broader impact of the project is that a new generation of global models of the Sun-heliosphere system will be delivered to the CCMC to enable broad use by the solar-heliophysics community. The project will involve the training of a junior female postdoctoral researcher and will enhance infrastructure for research and education.
