A movie of the variation of the geomagnetic field at the surface of the Earth due to the ionsopheric current systems. The equatorial intensification of the magnetic field is due to the Equatorial Electrojet (EEJ). UT = universal time. The unit is nT (nano-Tesla). The movie was generated using a geomagnetic field model (CM4) . This was presented in a meeting in Potsdam, Germany in 2006. http://en.wikipedia.org/wiki/Equatorial_electrojet
