Highly accurate magnetometers on recent satellite missions have made it possible to detect small ionospheric currents on a global scale. During the night-time, the ionosphere is typically very quiet, however, there are still F-region currents driven by the gravitational field and by magnetic pressure gradients. The signature from these currents have historically been difficult to detect, but magnetic data from the CHAMP satellite mission can be processed to recover these small signals. In this work, we use the TIEGCM electrodynamic solver along with empirical density and wind inputs from the International Reference Ionosphere (IRI), the MSIS neutral atmosphere model, and Horizontal Wind Model (HWM), to provide a solution for the currents and electric fields in the global ionosphere. The gravity and magnetic pressure driven components are then extracted and compared with CHAMP observations. This work aims at extending the TIEGCM ionospheric modeling capability to analyze and interpret satellite magnetic field measurements from CHAMP, C/NOFS and the upcoming Swarm mission.
