与澳大利亚、巴西、加拿大、中国、印度尼西亚、日本、韩国、密克罗尼西亚、巴布亚新几内亚、秘鲁、菲律宾、俄罗斯、台湾、越南、美国等30多个组织合作，沿210度磁子午线，从高纬度经中低纬度至赤道地区，跨越L=8.50-1.00，开展了多国协同观测。有组织的地面磁场网数据可以(1)研究太阳风能量向地球磁-电离层-大气系统的传递过程，(2)阐明磁层现象从极地到赤道的全球传播、传递和耦合过程。2000-2002年期间，开展了以下多国协调的观测和研究项目；(1)为了明确极地和赤道地区磁层现象之间的关系，我们在西伯利亚、阿拉斯加、菲律宾、关岛和雅浦等地进行了210 MM台网的磁场和电场观测，并与加拿大、巴西和秘鲁等国的研究所协商开展了协同磁层观测。(2)东京大学和名古屋大学在STEP期间在加拿大安装的光学和磁性设备（即全天候电视摄像机、感应和磁通门磁强计）重新用于全球网络观测。(3)在韩国、夏威夷、巴布亚新几内亚、波纳佩、印度尼西亚和澳大利亚等太平洋地区的中低纬度站进行了磁观测，研究了磁层现象从极地到赤道的传播和传递过程。(4)特别是在菲律宾的宿务和达沃，密克罗尼西亚的波纳佩、雅浦、关岛和圣诞岛等西太平洋地区沿倾角赤道的电磁观测，研究了赤道电喷流的动力学及其相关现象。(5)为了有效地分析数据，并与国际空间研究计划卫星和其他地面网络交换数据，本项目的调查人员被派往2001年在河内举行的国际空间研究所会议和2002年在旧金山举行的亚洲空间研究所会议。(6) 2003年3月发表研究成果总结报告。从高纬度到赤道地区沿210°磁子午线和沿磁倾角赤道的跨国协调观测，可以获得研究磁层对各种太阳风变化响应的重要网络数据，阐明从极地到赤道地区DP 2 - pc3频率范围内磁层现象的全球传播和传递特征。少

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, China, Indonesia, Japan, Korea, Micronesia, Papua New Guinea, Peru, Philippines, Russia, Taiwan, Vietnam, and the United States. The organized ground network data of magnetic fields make it possible (1) to study solar wind energy transfer process into Earth's magneto-ionos-Atmosphere system, and (2) to clarify the global propagation, transfer, and coupling processes of magnetospheric phenomena from the polar to equatorial regions.During the period of 2000-2002, the following multinationally 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 ele … More ctric 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 (I.e., all-sky TV camerain, induction and fluxgate magnetometers) in Canada, which had been installed by University of Tokyo and Nagoya University during the STEP period, were re-used for the global network observations.(3) Magnetic observations at middle- and low-latitude stations in Korea, Hawaii, Papua New Guinea, Pohnpei, 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 Pohnpei, Yap, Guam and Christmas Island in Micronesia, were started to investigate dynamics of the equatorial electrojet current and the associated phenomena.(5) For effective data analyses and exchanges with the ISTP satellites and the other ground-based networks, the investigators of this project were dispatched to the IAGA Meeting, held at Hanoi in 2001, and the AGU meeting, held at San Francisco in 2002.(6) Summary report of research results was published in March, 2003.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 magnetospheric responses to various changes in the solar wind, and clarify the global propagation and transfer characteristics of magnetospheric phenomena in the frequency range of DP 2 - Pc 3, from the polar to equatorial regions.
