A large observation network with the SuperDARN radars and other ground-based instruments at manned and unmanned stations is currently developed in the Antarctic area from sub-auroral latitudes to polar cap region and from nightside to dayside hours under international collaboration. Such a widespread circumpolar observation network is very unique and powerful for studies on the phenomena which occur due to the Sun-Earth interaction, e.g., direct entry of solar wind energy and momentum into the cusp and polar cap regions, explosive energy dissipation during substorm-time, highly energetic particle precipitation into the atmosphere during storm-time. Coordinated observations with several low-altitude satellites (e.g., NOAA, DMSP, etc.) and magnetospheric satellites (e.g., THEMIS/ARTEMIS, Geotail, MMS, ERG, etc.) can be also expected In our presentation, current status and future plan of NIPR-related project will be introduced, and importantce of such a widespread ground-based observation network in Antarctica will be explained and discussed.
