arnoldyuki@serc.kyushu-u.ac.jp One purpose of Solar Terrestrial Physics (STP) research in the twenty-first century is to support human activities in Space from the aspect of basic research. The scientific aim of the STP community is the creation of new physics: (1) couplings of the complex and composite systems and (2) macro-and-micro-scale couplings in the Solar-Planetary system. The intention is to construct a new Network of Stations for ground-based observations and for simulations/empirical modeling. The Space Environment Research Center (SERC), Kyushu University, is currently deploying a new ground-based magnetometer network, in cooperation with about 30 organizations around the world, in order to study the complex Sun-Earth system for space weather. SERC conducts MAGDAS (MAGnetic Data Acquisition System) observation at 50 stations in the CPMN (Circum-pan Pacific Magnetometer Network) region, and conducts frequency modulated continuous wave (FM-CW) radar observation along the 210° magnetic meridian during the IHY/IPY/eGY/ ILWS/CAWSES periods. From these network observations, we will clarify: (1) The dynamics of plasmaspheric changes during space storms and substorms, (2) Electromagnetic responses of magnetosphere-ionosphere-thermosphere complex system to various solar wind changes, and (3) penetration mechanisms of DP2-ULF range disturbances from the solar wind into the equatorial ionosphere. In the present paper, we will first introduce our real-time data acquisition and analysis system of MAGDAS/CPMN, which was deployed in 2005 and 2006, and preliminary results from the MAGDAS project. This project is actively providing the following: (1) Monitoring the global 3-dimensional current system to know the electromagnetic coupling of high-latitude and Sq current systems, and (2) Monitoring of the plasma density to understand space plasma environment change during space storms. We will also present our FM-CW radar system at L=1.26 to deduce the electric field from the ionospheric plasma drift velocity. From 24hr monitoring of the ionospheric drift velocity with 10-sec sampling by the FM-CW radar observation, we can understand how the polar electric field penetrates into the equatorial ionosphere.
