The investigators will produce a comprehensive picture of the coronal mass ejection (CME) phenomenon as viewed at radio wavelengths from lift-off at the sun through the response of the terrestrial magnetosphere to its passage. The main effort is to continue to synthesize radio data from the Wind and Ulysses spacecraft, SOHO coronagraph data, ground-based data, and corollary measurements from instruments monitoring the solar wind and energetic particle environment. The work builds on several significant advances made in a previous award from NSF. The investigators developed triangulation methods that permit investigators to track the sources of radio waves (CMEs and finite regions along their boundaries) as they move out from the sun long after they cease to be visible to SOHO instruments. With this technique, regions where the radio waves originate are identified to allow detailed study, using the multiple supporting datasets, of the physical processes that produce the waves.

研究人员将通过陆地磁层的响应到其通道的响应，从射线波长中观察到冠状质量弹出（CME）现象的全面图片。主要的工作是继续从风和尤利西斯航天器，SOHO CORONAGRAPH数据，基于地面的数据以及从监控太阳风和能量粒子环境的工具中综合无线电数据。这项工作是基于NSF先前奖项取得的几项重大进步。研究人员开发了三角剖分方法，使研究人员可以跟踪无线电波（CMES和有限区域沿其边界）的来源，因为他们在停止后很长一段时间从阳光下迁出，因此可以看到Soho仪器。使用此技术，确定无线电波的区域可以使用产生波浪的物理过程的多个支持数据集进行详细研究。
