A tomographic technique will be used to map solar wind structures, determine the extent of their interactions with the Earth, and locate their origins in the solar corona. The basic input data are interplanetary radio scintillation measurements supplied by the Solar Terrestrial Environment Laboratory of the Nagoya University (Japan). These are combined with a sophisticated numerical magnetohydrodynamic model of the heliosphere in order to reconstruct the trajectories of propagating interplanetary disturbances. This technique will be applied in real-time to ground and space-based data, and the results will be made available to the international community through the NOAA web-site. This study will allow the visualization of the extensive region between the Sun and the Earth with a novel level of completeness.

层析成像技术将用于绘制太阳风结构，确定其与地球相互作用的程度，并将其起源定位在太阳电晕中。基本的输入数据是纳戈亚大学（日本）太阳陆地环境实验室提供的星际无线电闪烁测量。这些结合了Heliosphere的复杂数值磁流失动力学模型，以重建传播行星际障碍的轨迹。该技术将实时应用于地面和空间数据，结果将通过NOAA网站提供给国际社会。这项研究将允许以新颖的完整水平来可视化太阳和地球之间的广泛区域。
