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).

该团队将采用他们开发的三维（3D）层析成像技术，以分析通过地面际闪光闪烁（IPS）仪器获得的实时地球层等离子体观测值和Coriolis Spacecraft上的太阳能质量射击成像器（SMEI）仪器。该团队还将使用太阳陆地关系天文台（立体声）航天器的观察结果来确定其环境地球环境，重建由立体声远程和原位观察到的等离子体结构的形状，并评估和改进其现有的西班牙造影模型和技术。首席研究者（PI）将继续合作，与日本的太阳能环境实验室（Stelab）以及印度的Ooty射电望远镜进行观察，以期预计将有助于持续部署NSF资助的NSF资助的Murchison广场阵列（MWA）在澳大利亚的PROVINEDERS。对于竞选活动和协作研究的太阳能，地球际和星际环境（Shine）社区，汤森散落的数据具有特定的兴趣。该团队将测试基于地面和空间的遥感观测值，以确定这些观察结果最佳地提供了全局3D地震密度和速度测量的程度。该团队还计划将太阳能磁场包括的太阳风模型合并到其太阳能速度和密度的整体扫描重建中。 PI团队提供的分析使否则难以描绘的太阳和地球之间的区域可见。他们的层析成像模型目前可在NASA Goddard太空飞行中心的社区坐标模型中心提供，用于“重新运行”，允许全球研究人员使用。作为这项工作的一部分，PI的3D断层扫描技术制作的图像和动画将通过Internet作为加利福尼亚大学迭戈大学的档案数据集提供。该档案将是一种有价值的教育工具以及太空天气预报工具，用于研究冠状质量弹药的全球性能（CMES），共旋转等离子体结构和太阳能风相互作用。这项奖项是根据2009年的《美国恢复和重新投资法》（公共法律111-5）资助的。
