DMSP F16 observations of Poynting flux (blue) and ion temperature, T_i (red) along the satellite orbit track for the same four orbits as shown in Figure 6. Poynting flux is plotted with maximum positive values toward the dayside, i.e. upward from the orbit track. T_i is plotted with maximum positive values toward the nightside, i.e. downward from the orbit track In each panel, the hemisphere and time of F16 crossing the highest latitude are indicated at top left. The location of the CRBs is shown by gray lines perpendicular to the orbit track. The scale for Poynting flux and T_i are shown to the right of each NH panel.
