GLOBAL MAGNETOMETERS

GLOBAL MAGNETOMETERS

The following tables identify 111 worldwide magnetometer sites intended to provide global coverage. These sites have been identified as part of the activities of STEP Project 6.4 Ground-Based Magnetometers. The contact points for this project are M. Teague, V. Papitashvili and E. Friis-Christensen. Descriptions of STEP Project 6.4 have been given in STEP International Volume 2, Number 10 and Volume 3, Number 1. There are approximately 200 magnetic observatories worldwide and the following stations have been determined by adopting an elementary cell of approximately 2000 km square and endeavoring to locate at least one station within each cell. The cell size in the Magnetic Latitude/Magnetic Local Time coordinate system is shown in Table 1.

The stations have been grouped into the 5 key regions shown in Table 1 and defined by various ranges in Corrected Geomagnetic (CGM) Latitude. Statistical boundaries between the different geomagnetic regions have been used which provide data to solve quite different geophysical problems and determine certain magnetic indices: a) polar cap - directly-driven processes of the "solar wind - magnetosphere" interaction; b) auroral zone - storage of the energy from this interaction in the magnetospheric tail and its release during magnetic storms and substorms; c) middle latitudes - magnetosphere-ionosphere coupling and ionospheric processes, and; d) low latitudes and equatorial region - ring current, magnetic storms, equatorial electrojet, and ionospheric anomaly. The magnetometer sites selected for each of these regions are shown in Tables 2 through 6. Certain of these sites are associated with various projects and networks and these are indicated in the right-hand column of these tables.

Certain data from these sites are available through the NOAA/NGDC
