Modelled UT-F sensitivity patterns for aa′ = 88.15 nT and so corresponding to the data shown in Figure 3. Sensitivities are modelled for the year 1988 at the same times as each 3-hourly aa data point and the data then processed exactly as are the data in Figure 3 and plotted using exactly the same scales and colour scales: (a) ; (b) ; (c) S aa; and (d) .
