SHINE: Systematic Evaluation of the Coronal and Heliospheric Models Installed at the Community Coordinated Modeling Center (CCMC)

首席调查员(PI)和她的合作者将评估目前在NASA戈达德太空飞行中心的社区协调建模中心(CCMC)托管的几个模型的成功，以确定如何最好地使用这些模型，以及如何改进它们。这项工作将特别侧重于Wang-Sheeley-Arge(WSA)日冕模式、磁流体绕A球日冕模式(MAS)、ENLIL日球层/太阳风模式(“Enlil”是苏美尔风神)和空间天气模拟框架(SWMF)，以便系统地评估它们在2007-09年太阳活动最短期间模拟太阳日冕和太阳风结构的能力。为了将模型输出与多航天器观测进行比较，Pi的团队将测试每一次太阳卡林顿自转和每个可用作观测源的航天器的大约246个模型运行，以便全面评估不同航天器测量的不同太阳边界条件造成的模型输出差异，而不是不同模型中不同物理或数值处理造成的差异。由于这些团队成员不参与特定模型的开发，因此他们可以对每个模型的优缺点进行公正的评估，并通过这种方式帮助原始开发人员进行模型验证和增强。这一努力将提高社区使用CCMC的模型准确模拟内日光层中的太阳风演变并将太阳上发生的现象与太阳风结构联系起来的能力。对CCMC的日冕和太阳风模型的评估是验证在空间物理研究和空间天气预报方面取得进一步进展所需工具的必要步骤。PI是一名年轻的女性博士后，她将通过这个项目接受指导和职业发展，从而加强代表不足的群体在自然科学领域的参与。该合作伙伴还将把这些成果纳入他教授本科生和研究生的课程。该小组将通过参加年度科学会议和讲习班广泛传播这些研究成果。

The Principal Investigator (PI) and her collaborator will evaluate the success of several models now being hosted at the Community Coordinated Modeling Center (CCMC) at NASA's Goddard Space Flight Center, to determine how these models can best be used and how they could be improved. This effort will specifically focus on the Wang-Sheeley-Arge (WSA) coronal model, the Magnetohydrodynamics-Around-A-Sphere (MAS) coronal model, the ENLIL heliospheric/solar wind model ("Enlil" was the Sumerian wind god), and the Space Weather Modeling Framework (SWMF), in order to systemically evaluate their capabilities in simulating the solar corona and solar wind structure for the solar minimum period of 2007-09. To compare model output with multi-spacecraft observations, the PI's team will test about 246 model runs for each solar Carrington rotation and for each available spacecraft as an observation source, in order to fully assess the differences in model output caused by the varying solar boundary conditions measured by different spacecraft, as opposed to variations caused by different physics or numerical treatments in the various models. Because these team members are not involved in developing specific models, they can provide an unbiased evaluation of the advantages and disadvantages of each model and in this way, assist the original developers with model validation and enhancement. This effort will advance the community's ability to use the models at the CCMC to accurately simulate solar wind evolution in the inner heliosphere and to connect phenomena occurring on the Sun with solar wind structures. This evaluation of the CCMC's solar corona and solar wind models is a necessary step in validating the tools needed for further advances in space physics research and in space weather forecasting. The PI is a young female postdoc who will receive mentoring and career development through this project, thereby enhancing the participation of underrepresented groups in the physical sciences. The Co-PI also will incorporate these results into his courses teaching undergraduate and graduate students. The team will disseminate these research results broadly through participation at annual scientific meetings and workshops.
