1 AU results of the EEGGL simulation of the 12 July 2012 CME event simulated at CCMC. Shown are the simulated and observed plasma quantities plotted with dashed and solid lines, respectively. From top to bottom are the magnetic field component B_x, B_y and B_z, the mass density, and the Earth-directed velocity V_x. Simulation results are shifted 10 h to match the shock arrival. We find good agreement, with the exception of the B_x–B_y rotation and the excessive trailing velocity.
