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.

将使用层析成像技术绘制太阳风结构图，确定其与地球相互作用的程度，并确定其在日冕中的起源。基本输入数据是由（日本）名古屋大学日地环境实验室提供的行星际无线电闪烁测量数据。这些都结合了一个复杂的数值磁流体动力学模型的日光层，以重建传播行星际扰动的轨迹。这一技术将实时应用于地面和空间数据，其结果将通过诺阿网站提供给国际社会。这项研究将使太阳和地球之间的广阔区域的可视化具有新的完整性。
