Collaborative Research: The Community-Based Whole Magnetosphere Model (CWMM)

该项目将开发和验证一个以社区为基础的全磁层模型，该模型模拟太阳风和行星际磁场与近地空间环境的相互作用。该模型将从地球表面上方100公里延伸到磁层弓激波之外。基于社区的全磁层模型(CWMM)将模拟磁场和电场、中性和等离子体成分、压力和速度以及高能粒子环境。将使用数据同化，使模式与数据更一致。为实现这一目标，空间科学界各小组开发的个别区域模型将用作CWMM的组成部分。这些模型将使用空间天气建模框架(SWMF)耦合在一起。由此产生的耦合模型将通过社区协调建模中心提供给空间科学界和空间气象界。严格的验证过程将量化模型的准确性随着更多组件的添加而发生的变化。该项目将使耦合模型进入运行状态，供空军气象局和NOAA空间环境中心(SEC)使用。该项目的成果也将用于密歇根大学正在开发的空间气象课程。该项目由美国宇航局和美国国家科学基金会共同资助。

This project will develop and validate a community-based whole magnetosphere model that simulates the interaction of the solar wind and interplanetary magnetic field with the near-Earth space environment. The model will extend from 100km above the Earth's surface to outside of the magnetospheric bow shock. The Community-based Whole Magnetosphere Model (CWMM) will model the magnetic and electric fields, neutral and plasma composition, pressure, and velocities, and energetic particle environment. Data assimilation will be used to make the model more consistent with the data. To achieve this goal, models of individual regions developed by various teams in the space sciences community will be used as components in the CWMM. The models will be coupled together using the Space Weather Modeling Framework (SWMF). The resulting coupled model will be made available to the space science and space weather communities through the Community Coordinated Modeling Center. A rigorous validation process will quantify how the accuracy of the model changes as more components are added. The project will move the coupled model toward operational status for use by the Air Force Weather Agency and NOAA's Space Environment Center (SEC). Results from this project will also be used in the Space Weather curriculum that is being developed at the University of Michigan. This project is jointly funded by NASA and NSF.
