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.

提议者将通过将SAIC的MAS代码与科罗拉多州的Enlil Code相结合，这是当今可用的最复杂的模型之一，来开发用于太阳能物理建模的战略能力。耦合MAS和ENLIL将提供最先进的技术，以推导时间依赖时间的光电磁场数据，并导致GUI驱动的产品，该产品将广泛吸引太阳能和地球科学界。提议的团队包括太阳能磁力测定法，表面通量演化建模，冠状和太阳风建模以及计算物理学的专家。他们的新模型将封装MAS和ENLIL的能力，以及在本工作过程中将开发和合并的重要改进。观察到的光球磁场是MAS和ENLIL模拟的主要边界条件，它们的太阳风解决方案在很大程度上取决于这些边界条件。因此，拟议的工作包括详细的研究，以提高该观察性输入的质量。提议者打算通过通量传输代码的时间依赖的输出来推动其新模型，从而产生将交付到社区协调建模中心（CCMC）的太阳风的实时模型。最终，该模型可能会替代科罗拉多州博尔德国家气象服务部太空环境中心的当前Wang-Sheeley-Arge模型。虽然全球磁水动力学（MHD）模型是必要的，但建议者计划通过提供均匀的GUI界面来启动模型运行，以最大程度地减少用户的不必要并发症。这里的合作者还将提供一组GUI工具，用于后处理，分析和可视化模型输出，因为这项工作的大部分已经作为以前和正在进行的程序的一部分完成。
