Space Weather: Characteristics and Dynamics of CME Induced Radio Emissions

研究人员将通过地球磁层对日冕物质抛射现象的反应，绘制从太阳升空到无线电波长观测到的日冕物质抛射现象的全面图像。主要的工作是继续综合Wind航天器和近地天体航天器的无线电数据、SOHO日冕数据、地面数据以及监测太阳风和高能粒子环境的仪器的必然测量结果。这项工作建立在NSF以前的奖项中取得的几项重大进展的基础上。研究人员开发了三角测量方法，使研究人员能够跟踪无线电波的来源（CME及其边界沿着的有限区域），因为它们在SOHO仪器不再可见之后很久才从太阳移动。通过这种技术，可以识别无线电波起源的区域，以便使用多个支持数据集对产生电波的物理过程进行详细研究。

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.
