Ground Geomagnetic Field Data Along the 210”EMagnetic
Meridian (one-minute averages) 2002-2003
OB0057


This CD-ROM contains ASCII files and gif plots of the one-minute averaged magnetic field data obtained from ground-based stations along the 210”Emagnetic meridian. The data in this CD-ROM are most suitable for use on WINDOWS 95/98/2000/XP.

1. Data Plots

Please see index.html using some WWW browser, e.g., Netscape, Internet Explorer, etc. The plot files are available in xbm (gif) format (one file/day/all stations). A list of the stations and other remarks are also available.

2. Digital Data in ASCII Format

The data file is in ASCII format (one file/day/station) with a name of a5yymmdd.stn where yymmdd represents the year, month, and day for the data and stn represents the three-digit abbreviation of the station name.

Please consult the README.TXT file for the file format.

3. Notes

* Please contact the principal investigator, Professor K. Yumoto, Kyushu University, before using the data at any publication and/or presentation. If the data are essential to your research, the PI will require coauthorship, acknowledgements, and related references. These collaborations are very important for the continuation of the 210 MM project.

4. The 210 MM Magnetic Observation Group

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.

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.
