SHINE: Imaging and Analyses of Heliospheric Structures for Using InterPlanetary Scintillation (IPS) and Solar Mass Ejection Imager (SMEI)

该团队将应用他们开发的三维（3D）层析成像技术来分析由地面行星际闪烁（IPS）仪器和Coriolis航天器上的太阳质量喷射成像仪（SMEI）仪器获得的实时日光层等离子体观测。该小组还将利用日地关系观测站航天器的观测结果确定其周围日光层环境，重建由日地关系观测站远程和现场观测到的等离子体结构的形状，并评价和改进其现有的层析成像模型和技术。首席研究员（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，预计将有助于正在西澳大利亚州建造的NSF资助的Murchison宽场阵列（MWA）的持续部署。PI计划对现有的IPS无线电数据和SMEI Thomson进行更全面的分析，太阳、日光层和行星际环境（SHINE）社区特别感兴趣的散射数据，用于活动活动和合作研究。该团队将测试地基和天基遥感观测，以确定这些观测在多大程度上可以最好地用于提供全球三维日光层密度和速度测量。该团队还计划将包括太阳风磁场的太阳风模型纳入其太阳风速度和密度的层析重建中。PI团队提供的分析使太阳和地球之间的一个区域变得可见，否则很难描绘。他们的层析成像模型目前可在美国宇航局戈达德太空飞行中心的社区坐标建模中心“按需运行”，允许世界各地的研究人员使用。作为这项工作的一部分，PI的3D断层扫描技术产生的图像和动画将通过互联网作为加州大学圣地亚哥分校的档案数据集提供。这个档案将是一个有价值的教育工具，以及空间天气预报工具，用于研究日冕物质抛射（CME）的全球性质，同向旋转等离子体结构，和太阳风的相互作用。这个奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。

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).
