Effect of IMF Variability

As shown by the solid line in Figure 4b, the IMF is responsible for much of the short time variation in the model magnetic field residuals as well as some of the longer lasting trends such as positive dBx and negative dBz on Jan 10. In the T96_01 model the IMF inputs affect both tail and field aligned currents as well as the interconnection fields in the boundary layer. Thus in the observed MFE residuals in Figure 3 a good portion of the short time variability is most likely due to tail and field aligned currents controlled by the changing IMF.
