The team will apply a three-dimensional (3D) tomographic technique they have developed to analyze real-time heliospheric plasma observations obtained by ground-based interplanetary scintillation (IPS) instruments and the Solar Mass Ejection Imager (SMEI) instrument on the Coriolis spacecraft. This team will also use observations from the Solar Terrestrial Relations Observatory (STEREO) spacecraft to determine its ambient heliospheric environment, to reconstruct the shapes of plasma structures observed remotely and in situ by STEREO, and to evaluate and refine their existing tomographic models and techniques. The Principal Investigator (PI) will continue collaborations in making IPS observations with the Solar-Terrestrial Environment Laboratory (STELab) in Japan and with the Ooty Radio Telescope in India, in anticipation of assisting the ongoing deployment of the NSF-funded Murchison Widefield Array (MWA) being constructed in Western Australia.The PI plans to perform more complete analyses of existing IPS radio data and SMEI Thomson-scattering data that are of specific interest to the Solar, Heliospheric, and INterplanetary Environment (SHINE) community for campaign events and collaborative studies. The team will test both ground-based and space-based remote-sensing observations to determine the extent to which these can best be used to provide global 3D heliospheric density and velocity measurements. The team also plans to incorporate solar wind models that include solar wind magnetic fields into their tomographic reconstructions of solar wind velocity and density. The analyses provided by the PI's team make visible a region between the Sun and Earth that is otherwise difficult to depict. Their tomographic model is currently available at the Community Coordinate Modeling Center at NASA Goddard Space Flight Center for "runs-on-request," allowing use by researchers worldwide. As part of this effort, the images and animations produced by the PI's 3D tomography technique will be made available via the internet as an archival data set at the University of California-San Diego. This archive will be a valuable education tool, as well as a space weather forecasting tool, for the study of the global properties of Coronal Mass Ejections (CMEs), co-rotating plasma structures, and solar wind interactions.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

该团队将应用他们开发的三维(3D)层析技术来分析由科里奥利斯航天器上的地面行星际闪烁(IPS)仪器和太阳质量抛射成像仪(SMEI)获得的日球层等离子体实时观测。该小组还将利用日地关系天文台(STEREO)航天器的观测来确定其周围的日光层环境，重建STEREO远程和现场观测到的等离子体结构的形状，并评估和改进其现有的断层成像模型和技术。首席调查员(PI)将继续与日本的日地环境实验室(STELab)和印度的Ooty射电望远镜合作进行IPS观测，以期协助正在西澳大利亚建造的由NSF资助的Murchison Widefield阵列(MWA)的持续部署。PI计划对现有的IPS无线电数据和SMEI汤姆森散射数据进行更全面的分析，这些数据是太阳、日球层和星际环境(SISH)社区特别感兴趣的，用于宣传活动和合作研究。该小组将测试地面和空间遥感观测，以确定这些观测在多大程度上可以最好地用于提供全球3D日光层密度和速度测量。该团队还计划将太阳风模型纳入他们对太阳风速度和密度的断层重建中，其中包括太阳风磁场。PI的团队提供的分析显示了太阳和地球之间的一个区域，否则很难描绘出来。他们的断层摄影模型目前可以在NASA戈达德太空飞行中心的社区坐标建模中心获得，供世界各地的研究人员使用。作为这项努力的一部分，PI的3D断层成像技术产生的图像和动画将作为加州大学圣地亚哥分校的档案数据集通过互联网提供。该档案将是研究日冕物质抛射、共转等离子体结构和太阳风相互作用的全球性质的宝贵教育工具和空间气象预报工具。
