The main goal of this 3-year SHINE project is to apply the tomographic analysis to heliospheric data from available remote-sensing observations of interplanetary scintillation (IPS), archival white-light observations from SMEI (Solar Mass Ejection Imager), and extend this technique to the HI-2 (Heliospheric Imager-2) instruments onboard the STEREO spacecraft. This research effort will allow the project team to discover the differences between their own robust measurements of the kinematic propagation of these parameters near the Earth and the physical processes governing the propagation of features from near the solar surface using three-dimensional (3D) magnetohydrodynamic (MHD) models. The project contributes to broader societal activities, such as advancing the participation of women in science and improving the scientific literacy of the general public. The project team will present the results of this research project at national scientific meetings and will publish them in peer-reviewed scientific journals. The research and EPO agenda of this SHINE project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.The research agenda of this SHINE project consists of four main tasks, namely: (i) compare the University of California in San Diego (UCSD) tomographic modeling with MHD modeling to learn the physical differences between these two very different types of remote sensing analyses; (ii) pursue inter-comparison of 3D MHD modeling techniques that all use the same boundary conditions in order to learn the best physical parameters needed to propagate time-dependent structures; (iii) perform analysis of these interplanetary structures in order to determine and provide the lacking magnetic field inputs required for the tomographic kinematic model propagation; and, (iv) perform new analyses using iterative 3D MHD codes that refine remote sensing observations from solar heliospheric observations and IPS measurements. The outcome of this research project is expected to yield new improved boundary inputs, based on multiple data sets (that incorporate both remote-sensing observations and in-situ measurements), for various 3D MHD models, and especially for Space Weather models, and an analysis that displays the global properties of heliospheric structures. The project would provide new physical insight on "the solar cycle dependence of CMEs, including their propagation through and their interaction with the background solar wind, including the linking of interplanetary and near-Sun phenomena," as stated in the goals of the NSF's SHINE program.

这个为期三年的光泽项目的主要目标是将层析成像分析应用于可用的星际闪烁（IPS）的可用遥感观察结果（IPS），SMEI（太阳能质量射击成像仪）的档案白灯观察结果，并扩展此技术，并扩展此技术立体声航天器上的HI-2（Heliospheric Imager-2）仪器。 这项研究工作将使项目团队能够发现他们自身对地球附近这些参数的运动学传播的稳健测量和使用三维（3D）磁性磁性流动学（ MHD）模型。 该项目有助于更广泛的社会活动，例如推进妇女参与科学的参与并提高公众的科学素养。 项目团队将在国家科学会议上介绍该研究项目的结果，并将在经过同行评审的科学期刊上发布。 该Shine项目的研究和EPO议程支持AGS分部在发现，学习，多样性和跨学科研究方面的战略目标。该Shine项目的研究议程包括四个主要任务，即：（i）比较该大学通过MHD建模的圣地亚哥（UCSD）层析成像建模的加利福尼亚，以了解这两种非常不同类型的遥感分析之间的物理差异； （ii）追求3D MHD建模技术的相互比较，这些技术都使用相同的边界条件，以了解传播时间相关结构所需的最佳物理参数； （iii）对这些星际结构进行分析，以确定和提供层析成像运动模型传播所需的缺乏磁场输入； （iv）使用迭代3D MHD代码进行新的分析，从而优化了来自太阳能地球层观测值和IPS测量值的遥感观察结果。 该研究项目的结果有望基于多个数据集（包括遥感观测值和原位测量值），对于各种3D MHD模型，尤其是对于太空天气模型，以及一个基于多个数据集（包含遥感观测值和原位测量值），以及一个基于多个数据集，预计该研究项目的结果将产生新的改进的边界输入。分析显示地球结构的全局特性。 该项目将提供有关“ CMES的太阳周期依赖性，包括它们通过其传播以及与背景太阳风的互动，包括星际际和近似现象的联系”的新物理见解，如NSF Shine的目标中所述程序。
