The ERG (Exploration of energization and Radiation in Geospace) project is a mission to elucidate acceleration and loss mechanisms of relativistic electrons around Earth during geospace storms. The project consists of the satellite observation team, the ground-based network observation team, and the integrated data analysis/simulation team.
The ERG Science Center is operated by Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA) and Institute for Space-Earth Environmental Research (ISEE), Nagoya University as a Joint Research Center for Space Science. The science center archives data related to the ERG project, releases the data to the public, develops integrated analysis tools for the data, and promotes studies related to the ERG project.
