A combined global magnetohydrodynamic (MHD) model of the solar corona and inner heliosphere will be used to interpret SOHO and Yohkoh solar observations in addition to ACE and Ulysses in-situ measurements of coronal mass ejections (CMEs). SAIC's global model will be employed to initiate the CME disturbance and follow its evolution out to 20 solar radii. NOAA/SEC's heliospheric model will subsequently pick up these structures at 20 solar radii and propagate them out to 5 AU. Thus a global context will be constructed wherein one may connect the disparate solar and in situ observations. A unique and powerful perspective is thus provided to address fundamental issues concerning the origin, magnetic topology, and space weather evolution of CMEs. The events identified for simulation are to be selected by the SHINE community, and the simulation results will be available to the community on-line, in order to enhance the scientific return of this investigation.

除ACE和ulysses的冠状质量射出（CMES）外，还将使用太阳能电晕和内层的整体磁流体动力学（MHD）模型来解释Soho和Yohkoh太阳能观测值。 SAIC的全球模型将用于启动CME干扰，并遵循其演变至20个太阳半径。 NOAA/SEC的Heliosperic模型随后将在20太阳半径上拾取这些结构，并将它们传播到5 AU。因此，将构建一个全球环境，其中一个人可以连接不同的太阳能和原位观察。因此，提供了一个独特而有力的观点，以解决有关CME的起源，磁性拓扑和太空天气演变的基本问题。 Shine社区将选择用于模拟的事件，并将在线向社区提供仿真结果，以增强该调查的科学回报。
