Space Weather Operations-to-Research (O2R): Physics-Based Extension of the Wang-Sheeley-Arge (WSA) Model Capabilities

这是一项为期一年的试点研究计划，旨在扩展目前预测太阳风的业务能力，太阳风是地球环境中空间天气的驱动因素。这项研究将加强对太阳风基本过程的理解，并使进一步的研究向业务(R2O)过渡到模拟和预报动态空间天气事件的预测工具。该研究项目还将为空间天气的学生提供教育和培训机会。这是一个为期一年的试点研究计划，旨在扩大目前预测太阳风环境状态的业务能力。Wang-Sheeley-Arge(WSA)模型目前用于太阳风的业务预报。基于最新的太阳磁场天气图，半经验WSA模式提供了日冕(SC)和内日球层(IH)之间球面上太阳风参数的分布。这项研究将开发一个基于物理的自洽模型，以了解和预测日冕(SC)的环境状态。这项研究将(1)加强对基本过程的理解，(2)提高我们在SC和IH中模拟和预测环境状态的能力，以及(3)允许进一步的研究到业务(R2O)过渡到模拟和预测动态空间天气事件的预测工具。基于阿尔芬波湍流的SC的新模型将被交付给社区协调建模中心(CCMC)，以使太阳物理界能够广泛使用。观测者可以在CCMC实时运行模式，他们可以使用这些模式的结果来解释观测数据。该研究项目还将为学生提供教育和培训机会。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This is a 1-year pilot research program to extend the current operational capability of forecasting the solar wind, which drives space weather in the Earth's environment. The research will enhance understanding of the fundamental processes in the solar wind and allow the further Research to Operation (R2O) transition to a predictive tool to simulate and forecast dynamical Space Weather Events. The research project will also provide education and training opportunities for students in Space Weather.This is a 1-year pilot research program to extend the current operational capability of forecasting the ambient state of the solar wind. The Wang-Sheeley-Arge (WSA) model is currently used for operational forecasts of the solar wind. The semi-empirical WSA model provides a distribution of the solar wind parameters at a spherical interface between the Solar Corona (SC) and Inner Heliosphere (IH) based on the latest synoptic map for the solar magnetic field. The research will develop a physics-based, self-consistent model to understand and forecast the ambient state of the Solar Corona (SC). The research will (1) enhance understanding of the fundamental processes, (2) improve our capability to model and forecast the ambient state in both SC and IH, and (3) allow the further Research to Operation (R2O) transition to a predictive tool to simulate and forecast dynamical Space Weather Events. The new model for the SC based on the Alfven wave turbulence will be delivered to the Community Coordinated Modeling Center (CCMC) to enable broad use by the heliophysics community. Realtime runs of the model at CCMC will be available to observers, who can use these models results to interpret the observational data. The research project will also provide education and training opportunities for students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
