| Research Abstract |
Multinationally coordinated observations have been conducted along the 210 deg. magnetic meridian from high latitudes through middle and low latitudes to the equatorial region, spanning L=8.50-1.00, and along the magnetic dip equator, in cooperation with more 30 organizations in Australia, Brazil, Canada, Indonesia, Japan, Micronesia, Papua New Guinea, Peru, Philippines, Russia, Taiwan, Vietnam, and the United States. During the period of 2003-2005, the following multi-nationally coordinated observations and research project were performed ;
(1)In order to clarify the relationships of magnetospheric phenomena in the polar and equatorial regions, we conducted magnetic and electric field observations in Siberia, Alaska, Philippines, Guam, and Yap in the 210 MM network, and negotiated with the institutes in Canada, Brazil and Peru for collaborative magnetic observations.(2)Optical and magnetic equipments in Canada were re-used for the global network observations. (3)Magnetic observations a

t middle- and low-latitude stations in Hawaii, Papua New Guinea, Indonesia, and Australia in the Pacific region were also carried out to study the propagation and transfer processes of magnetospheric phenomena from the polar to equatorial regions. (4)Especially, electromagnetic observations along the dip equator in the west Pacific region at Cebu and Davao in Philippines, at Yap, Guam and Christmas Island, were started to investigate dynamics of the equatorial electro-jet current and the associated phenomena. (5)For effective data analyses and exchanges with the satellites and the other ground-based networks, the investigators of this project were dispatched to the international meetings. (6)Summary report of research results was published in March, 2006.
From the multinationally coordinated observations along the 210 deg. magnetic meridian from high latitudes to the equatorial region, and along the magnetic dip equator, we could get important network data to study the geospace environment change by energy and momentum transfer from the solar wind into the equatorial Ionosphere.
