AB: Global MHD simulations have shown increasing accuracy at reproducing magnetic storm features. One important feature that is necessary to predict, and which in fact can be used as a metric for accuracy of the simulation, is the geosynchronous magnetic field. In this paper we will present several comparisons of geosynchronous magnetic field measurements from the GOES spacecraft and results from the global Lyon-Fedder-Mobarry magnetohydrodynamic code for periods when it is driven by solar wind observations.
