The objective of this proposal is to use radio, white-light, and X-ray observations of the Sun, as well as in-situ plasma and particle data, to provide temporal and dynamic constraints that will lead to a better physics-based understanding of the origin, nature, dynamics, and interrelationship of individual solar transient phenomena (such as CMEs and solar energetic particles) that affect the near-Earth space environment. The PI's goal is to determine how the interpretation of solar radio data can benefit from the constraints imposed by complementary solar observations, and vice versa. The PI will focus on three interrelated areas: Coronal Mass Ejection (CME) origin and dynamics, the origin and propagation of accelerated solar energetic particles, and solar cycle comparisons of CME-generated radio emissions. To carry out these investigations, the low frequency radio data from the Wind, Ulysses, ISEE-3, and eventually STEREO spacecraft will be augmented with ground-based radio observations, as well as with soft and hard X-ray data, CME height-time and density data, solar images, and in-situ solar wind plasma and particle data. These various observations will be analyzed, within the context of appropriate physical models, to achieve a quantitative understanding of the interrelation of these solar transient phenomena and their relevance to space weather. These comprehensive analyses will advance the knowledge needed to track CMEs and solar energetic particle events to improve space weather predictions, as well as to quantify the characteristics and dynamics of these solar transients over the 11-year sunspot cycle.Contributing to broader impacts, the PI will establish and maintain a web-based public database of observed type II/IV radio events. He will also analyze individual type II events as these data are received. The results of these preliminary analyses will be e-mailed to other researchers and space weather forecasters. In addition to predicting the velocity profiles and Earth arrival times of CMEs, the PI's analyses will also help correlate particular solar events with space weather events. The PI will continue his participation in interdisciplinary conferences and workshops [e.g., SHINE, International Solar Cycle Studies (ISCS), and the Elmau/ISSI CME Workshops] and he will maintain and strengthen his collaboration with the theory group at the University of Sydney, including their Ph.D. students.

该建议的目的是使用对太阳的无线电，白光和X射线观测以及原位血浆和粒子数据，提供时间和动态的约束，从而使对个体，性质，动力学和相互关系的基于物理学的理解更好地理解单个太阳现象（例如CMES和SOLAR ENRAR ENRAR ENRICTIC），从而影响了附近的环境。 PI的目标是确定太阳无线电数据的解释如何受益于互补太阳观测的约束，反之亦然。 PI将集中于三个相互关联的区域：冠状质量弹药（CME）起源和动力学，加速太阳能颗粒的起源和传播以及CME生成的无线电排放的太阳周期比较。为了进行这些调查，将通过基于地面的无线电观测值以及软X射线数据，CME高度和密度和密度和密度数据，太阳能图像以及Situ Solar Wind Plasasma和颗粒数据和粒子数据和粒子数据和粒子和粒子数据，将增强来自风，Ulysses，ISEE-3的低频无线电数据。在适当的物理模型的背景下，将分析这些各种观察结果，以实现对这些太阳瞬态现象的相互关系及其与太空天气的相关性的定量理解。这些全面的分析将促进跟踪CME和太阳能颗粒事件所需的知识，以改善空间天气预测，并在11年的Sunspot循环中量化这些太阳瞬变的特性和动态。对更广泛的影响造成了更大的影响，PI将建立和维持基于Web的II IIV型无线电广播事件的基于Web的公共数据库。他还将在收到这些数据时分析单个II型事件。这些初步分析的结果将通过电子邮件发送给其他研究人员和太空天气预报员。除了预测CME的速度曲线和地球到达时间外，PI的分析还将有助于将特定的太阳事件与太空天气事件相关联。 PI将继续他参加跨学科会议和研讨会[学生。
