abstract. In order to investigate acceleration mechanisms of relativistic particles of the radiation belts and dynamics of geospace during space storms, the ERG (Energization and Radiation in Geospace) project is now under preparation. The project consists of satellite observation team, ground-network observation team, and simulation/integrated studies team. The satellite ERG (SPRINT-B) of ISAS/JAXA will be launched around 2014-2015, and is currently designed to have a comprehensive set of plasma/particle sensors as well as field and wave instruments. Coordinated observations with the ground-network observations such as magnetometer networks, SuperDARN HF radar networks, optical imager networks, and VLF wave networks are essential for the comprehensive understanding the dynamic of the inner magnetosphere. For the integrated data analysis using various kinds of data sets, the ERG science center develops the CDF of the project-related data as well as the plug-in tools for the THEMIS data analysis software (TDAS) in collaborating with the THEMIS project. As the pre-launch activity of the ERG-SC, the CDF files and the TDAS procedures for Japanese SuperDARN fitacf data (SYE, SYS, KSR and HOK) have been developed and are now available for Japanese STP researchers for the performance test. In this presentation, we will discuss about the possible collaborations between ERG and SuperDARN radar networks and show examples how the SuperDARN data can be analyzed in the TDAS.
