Maps of time-averaged magnetic variability, dB/dt (nT/s), of the radial magnetic field component obtained directly above the planetary surface. Co-latitude and longitude are shown on the Y and X axes, respectively. Upstream direction is at longitude below 180 degrees. Model results are shown in the left column for the DP and in the right column for the FR case. We show maps for B_p = 0 (top), 0.05 (middle) and 0.15 G (bottom).
