Variations of geomagnetic H, D, and Z field intensities on quiet days at west african latitudes

In the framework of the French participation to the International Equatorial Electrojet Year (IEEY), a network of ten electro-magnetic stations was installed at African latitudes. These stations measured digitally the three components of the magnetic field and the two components of the telluric...
