摘要: The ERG (Exploration of energization and Radiation in Geospace) project explores the acceleration, transport, and loss of relativistic electrons in the radiation belts. Radiation belts are regions of enhanced populations of energetic electrons and protons surrounding the Earth in the magnetosphere. For the first time, Taiwanese participate in a magnetospheric exploration mission － JAXA‐led ERG mission. Through years of efforts, Taiwan team has successfully delivered the LEP‐e (Lowenergy particle experiments–electron analyzer) for deployment on the ERG satellite. The ERG satellite has been successfully launched on December 20, 2016 from the Uchinoura Space Center. Besides the ERG satellite, spacecraft missions conducted by several countries have begun to work synergistically to explore the science associated with space weather. In addition, ground‐based network observatories also work closely together for revealing the complex dynamics of the Earth’s magnetosphere, which is strongly associated with the variability of space weather. To integrate the data from all the space‐borne and ground‐based assets can be daunting. The ERG project adopts the SPEDAS (Space Physics Environment Data Analysis System) as the project data analysis software. The development of SPEDAS is a key to efficiently study the space physics data in the golden era of space research.
