THE STEP 210 MAGNETIC MERIDIAN CHAIN DATA - 1-MIN AND 4-SEC DATA PLOTS K. Yumoto Space Environment Research Center, Kyushu University K. Shiokawa Solar-Terrestrial Environment Laboratory, Nagoya University, and The 210 MM Magnetic Observation Group
The coordinated ground-based magnetic observations during the STEP (Solar-Terrestrial Energy Program) period (1990-1995) were carried out to study energy and plasma transfer processes and global auroral dynamics. Topical Group 2.2 (Project Leader: Prof. S. Kokubun, Japan) set up by Working Group No. 2 for the STEP, was concerned with Coordinated Ground-Based Magnetic Observations for Studies on Response of the Magnetosphere an Magnetosphere-Ionosphere Coupling (COMOSM). Japanese ground-based observation teams participated the COMOSM programs. In order to organise the observations efficiently, working plans in Japan were grouped into four regional categories, i.e., the polar region, high-latitude conjugate region, middle and low lattitudes, and the equatorial zone.
During the STEP period (1990-1995), the STEL, Nagoya University (Y. Tanaka, K. Yumoto, K. Shiokawa) conducted multinationally coordinated magnetic observations along the 190, 210, and 250 (deg) magnetic meridians (MMs) in cooperation with and/or courtesy of the following institutes and organizations (co-investigator and cooperator names are in parentheses): University of Newcastle (B.J. Fraser, F.W. Menk), Electronics Research Laboratory, DSTO, Salisbury (K.J.W. Lynn, D.M. Sutton, Trevor Harris), Learmonth Solar Observatory (J. A. Kennewell) and Canberra Observatory of IPS Radio and Space Services (D.G. Cole, P. Wilkinson, R. Marshall), Mt. Stromlo Observatory (Vince O'Connor, Emanuel Vassiliadis), CSIRO Tropical Ecosystems Research Centre (L.K. Corbett, Tony Hertog), Weipa North State School (Michael and Chrisella Sbrizzi, Kath Newman, Pam Diggins), Albatross Hotel (Ron Doherty), Birdsville Police Station (W.J. Guan, Owen T. Harms), Dalby Agriculture College (G.K. Smith, Merv McGilchrist, L.R. Harris), Katanning Research Station, Great Southern Agriculture Research Institute (J. Montgomery, D. H. Ryall, Trevor Bell) and Australian Antarctic Division (R.J. Morris, R. Brown, P. Mantel, D, Lehmann, P. Jansen) in Australia; National Institute of Aeronautics and Space (LAPAN) (S.L. Manurung, Wilson Sinambela, Obay Sobari, Mamat Ruhimat, Sukmadradjat) in Indonesia; Tohoku University (T. Saito, T. Takahashi, T. Tamura, T. Sakanoi, H. Fukunishi), Tohoku Institute of Technology (M.

Krymsky, S.I. Solovyev, N. Molochushkin), Institute of Physics of the Earth (IFZ) (V.A. Pilipenko, L. Baransky), and Pacific Oceanological Institute(POI) (V.A. Akulichev, V.M. Nikiforov) in Russia; Lunping Observatory, Telecommunication Training Institute (Y.-H. Huang, S.-W. Chen) and Institute of Space Science, National Central University (J.K. Chao, J.Y. Liu) in Taiwan; and U.S. Geological Survey (A.W. Green, D.C. Herzog), Guam Magnetic Observatory (P. Hattori), Pacific Tsunami Warning Center (G.D. Burton, F. Takenouchi, M. Blackford,W.J. Mass, R.K. Nygard, Chip McCreery), Koror Observatory of the U.S. National Weather Service (Hirao Kloulchad), and University of Alaska, Fairbanks (S.-I. Akasofu, J. V. Olson, D. Osborne) in the United States.
* After the Principal Investigator, K. Yumoto, moved from the Solar-Terrestrial Environment Laboratory (STEL) to Kyushu University on February 1, 1996. The 210 MM magnetic observations are being conducted by Kyushu University and the database and archives are being maintained by STEL, Nagoya University. The contact person at STEL is K. Shiokawa.
