Collaborative Research: A Next-Generation Model of the Corona and Solar Wind

提出者将通过将上汽的MAS代码与科罗拉多州的ENLIL代码相结合来开发太阳物理建模的战略能力，这两个代码是当今可用的最复杂的模型之一。将MAS和ENLIL结合起来，将提供用于得出依赖时间的光球磁场数据的尖端技术，并产生一种图形用户界面驱动的产品，将广泛吸引太阳和日球层科学界。提出建议的团队包括太阳磁力测量、表面通量演变模拟、日冕和太阳风模拟以及计算物理方面的专家。他们的新模型将封装MAS和ENLIL的能力，以及将在这项工作过程中开发和纳入的重要改进。观测到的光球层磁场是MAS和ENLIL模拟的主要边界条件，它们的太阳风解强烈依赖于这些边界条件。因此，拟议的工作包括详细研究，以提高这一观测投入的质量。提出者打算用通量传输代码的时间相关输出来驱动他们的新模型，从而能够产生一个实时的太阳风模型，该模型将被交付给社区协调建模中心(CCMC)。最终，这个模型可能会取代科罗拉多州博尔德市国家气象局空间环境中心目前的Wang-Sheeley-Arge模型。虽然全球磁流体力学(MHD)模型必然是复杂的，但提出者计划通过提供统一的图形用户界面来启动模型运行，从而将不必要的复杂情况降至最低。这里的合作者还将提供一组用于模型输出的后处理、分析和可视化的图形用户界面工具，因为这些工作中的大部分已经作为以前和正在进行的计划的一部分完成了。

The proposers will develop a strategic capability for solar physics modeling by combining SAIC's MAS code with Colorado's ENLIL code, which are among the most sophisticated models available today. Coupling MAS and ENLIL will deliver cutting-edge techniques for deriving time-dependent photospheric magnetic field data, as well as result in a GUI-driven product that will appeal broadly to the solar and heliospheric scientific community. The proposing team includes experts in solar magnetometry, surface flux evolution modeling, coronal and solar wind modeling, and computational physics. Their new model will encapsulate the capabilities of both MAS and ENLIL, as well as important improvements that will be developed and incorporated during the course of this work. Observed photospheric magnetic fields are the primary boundary conditions to the MAS and ENLIL simulations, and their solar wind solutions are strongly dependent on these boundary conditions. Thus the proposed work includes detailed studies to improve the quality of this observational input. The proposers intend to drive their new model with time-dependent output from flux transport codes, allowing production of a real-time model of the solar wind which would be delivered to the Community Coordinated Modeling Center (CCMC). Ultimately, this model might replace the current Wang-Sheeley-Arge model at the National Weather Service's Space Environment Center in Boulder, Colorado. While global magnetohydrodynamic (MHD) models are, by necessity, complex, the proposers plan to minimize unnecessary complications for users by providing a uniform GUI interface with which to initiate model runs. The collaborators here will also provide a set of GUI tools for post-processing, analysis, and visualization of model output, since much of this work has already been done as part of previous and ongoing programs.
