Comparison of conductivity-corrected and modelled UT variations for (red) northern hemisphere, (blue) southern hemisphere, and (black) global indices. Each panel compares the conductivity corrected values (solid lines) and the modelled values (dot-dash lines) on the same plot, as in Figure 18d. (a) For dawn, Ncc(dawn), Scc(dawn) and cc(dawn) compared with Nm(dawn), Sm(dawn) and m(dawn); (b) for noon, Ncc(noon), Scc(noon) and cc(noon) compared with Nm(noon), Sm(noon) and m; (c) for dusk, Ncc(dusk), Scc(dusk) and cc(dusk) compared with Nm(dusk), Sm(dusk) and m(dusk); and (d) for midnight, Ncc(midn), Scc(dusk) and cc(dusk) compared with Nm(midn), Sm(midn) and m(midn).
