SuperMAG is a global collaboration that provides ground magnetic field perturbations from a long list of stations in the same coordinate system, identical time resolution and with a common baseline removal approach. For decades ground based magnetometers have proven to be the workhorse of magnetosphere- ionosphere physics and their importance is indisputable. This unique high quality dataset provides a continuous and nearly global monitoring of the ground magnetic field perturbation. This talk will focus on three topics associated with SuperMAG: 1) Motivation for SuperMAG. 2) Complications associated with global studies utilizing ground based magnetometer data. Focus will be on the automated procedure for determination of the undisturbed daily variations of the magnetic field observed by ground based magnetometers. The technique is validated by the use of data from published quiet days and our automated quiet day curve. The full-width-at-half-max (FWHM) of this difference varies from component to component and it depends on the magnetic latitude. We find that below 60 deg magnetic latitude the RMS error is <10nT. 3) The utilization of the unique near-global and continuous dataset. I illustrated this by showing results from two studies of the spatiotemporal behavior of the global auroral electrojet system. One of classical auroral substorms while the other investigates the response to an abrupt southward turning of the IMF.
