Reading solar system science

该提案中的项目推进了我们在太阳大气层、地球磁层和日光层内高能粒子的影响和性质的共同研究领域。来自太阳和银河系的高能粒子的调制决定了它们在日地环境中的丰度和能量，再加上辐射带内的波粒相互作用，确定了这些粒子在辐射带内的寿命。高能粒子辐照是航天器仪器系统可靠性的一个重要参数。与太阳风的短期和快速变化有关的日光层磁场的特征变化，如日冕物质抛射和同向旋转相互作用区，对于确定这些大的空间天气扰动影响地球空间环境的有效性非常重要。

The projects within this proposal advance our common research area of effects and nature of energetic particles within the sun's atmosphere, the earth's magnetosphere and the heliosphere. Modulation of energetic particles from both the sun and galactic sources determines their abundance and energies in the Sun-earth environment, which, together with wave-particle interaction within the radiation belts establishes the longevity of such particles within the radiation belts. Exposure to energetic particles is an important parameter in the reliability of spacecraft instrument systems. Characterising changes in the Heliospheric Magnetic Field associated with short and rapid variations in the solar wind, such as Coronal Mass Ejections and Co-rotating Interaction Regions, are important in determining the effectiveness with which these large Space Weather disturbance impact the Earth's space environment.
