The investigators will produce a three dimensional reconstruction of solar wind structures that interact with the Earth. The focus will be on the shape of the structures, the interaction of the structures with the ambient solar wind plasma, and the effect of the structures in modifying embedded solar magnetic fields. Their approach is to upgrade a tomographic technique now in use to investigate the structure of the quiet solar wind in three dimensions. Several remotely sensed datasets will be incorporated in the analysis, and the results will be checked against densities, velocities, and magnetic fields measured in situ by spacecraft where data are available.

研究人员将对与地球相互作用的太阳风结构进行三维重建。重点将放在结构的形状，结构与周围太阳风等离子体的相互作用，以及结构在修改嵌入式太阳磁场中的作用。 他们的方法是升级目前使用的层析成像技术，以研究三维空间中安静太阳风的结构。将把几个遥感数据集纳入分析，并将在有数据的情况下对照航天器现场测量的密度、速度和磁场对分析结果进行核对。
