Magnetometer Arrays by Region

Low Latititude Arrays

• Two-dimensional array of fluxgate magnetometers in China. First established in 1998. Magnetometers constructed by the UCLA magnetometer group.

• Two-dimensional array of fluxgate magnetometers in China. First established in 1998.

• An integration of the 210 MM Magnetic Observation Network (1990-1995) and Equatorial Magnetometer Network (1985-1995). First operated in 1996.

• Standard Observatories(AGSO)
• Research Observatories (Newscastle)

• One search coil magnetometer and one fluxgate magnetometer in Italy

Mid-Latititude Arrays

• Seven stations in the contiguous United States. Five of them form a line roughly at 55 degrees corrected geomagnetic latitude (cgm), and the other two are located at 40 degrees cgm. (1 sec)

• Standard Observatories(AGSO)
• Research Observatories (IPS Magnetometer Network)

    IGPP/LANL

• Two dimensional array of fluxgate magnetometers in the American continent. First established in 1997. (1 sec)

• A magnetometer array operated in N. W. Europe during the International Magnetospheric Study (IMS) (2.5 sec)

• An International Real-time Magnetic observatory Network started in 1989. More than 70 geomagnetic observatories are members of INTERMAGNET. (1 min)

• Three sites are at Tuckerton, New Jersey (since 1989), Pt. Arena, California (since 1992?), and Makaha, Hawaii (since 1995).

• A meridional array of paired magnetometers along the east coast of the United States. Begun in 1998.

Subauroral Arrays

    CPMN

    French Magnetometer Program

• Lead investigator: Jacques Bitterly, (jbitterly@ipgp.jussieu.fr)

Institute de Physique du Globe de Paris, Observatorire Magnetique,
Carrefour des 8 routes, 45340 Chambon La Foret, France

    INTERMAGNET

    The UK Sub-Auroral Magnetometer NETwork (SAMNET)

• SAMNET began taking data on the 1st of October, 1987. It has stations in the UK, the Faroe Islands, Sweden, Norway , Finland, Iceland and Russia. For the first 8 years of operation the sampling interval was 5 seconds, but since mid-november 1995 the stations have been recording at 1 second intervals.

Auroral Arrays

• CANOPUS consists of a network of automatic data collection stations in West-Central Canada, including the MARIA (MAgnetometer & RIometer Array) experiment that consists of thirteen stations. (5 sec)

    Geophysical Institute Magnetometer Array (GIMA)

• Originally established as the Alaskian Meridian Chain, the GIMA magnetometer array now has sites across Alaska and Western Canada

• Consists of 17 magnetometers Operated by Danish Meteorological Institute (DMI). Instruments are double-core tri-axial fluxgates. Data are sampled every 20 seconds (1-sec system has been installed at Sondrestromfiord).

• As a part of the MIRACLE ground-based network, the IMAGE magnetometer array consists of 27 magnetometers maintained by 9 institutes from Finland, Germany, Norway, Poland, Russia and Sweden. The stations cover geographic latitudes from 60 to 79 degrees. Its predecessor, EISCAT, started from 1982, and it is continued by IMAGE in 1991.

    MAGIC (Magnetometer Array on the Greenland Ice Cap)

• Consists of 4 tri-axis fluxgate variometer stations centered around the summit of the Greenland ice sheet. The data are sampled every 15 seconds.

High-Latitude Arrays

• AGO (Remote Site)
• Australian Antarctic Stations
• AAIMNET Searchcoils (IPS and Newcastle)
• Japanese
• SCAN Project: proposing 30 magnetometer stations (see map -- the stations will be placed along the two red dashed lines)
• French Antarctic Program
• Instruments are mu metal core search coils with magnetic flux feedback.

Pass band is .0007 Hz to 0.1 Hz. Data are sampled every 2 seconds.
• Italian
• Lucent Technologies
• U.K.
• Magnetometers at Halley and 4 AGOs
• Plan to deploy 10 more AGOs between Halley and South Pole

    MACCS (Magnetometer Array for Cusp and Cleft Studies)

• A high latitude array of 8 high time resolution magnetometers supplemented with high time resolution data from 4 standard observatories in northeastern Canada. The array was installed between August 1992 and August 1995. (5 sec)
