Scatter plots of the Rankin Inlet \( N_{\text{m}} F2 \) estimates versus CADI-based \( N_{\text{m}} F2 \) for matched moments and four local time sectors: a night \( 0 \pm 3\,\text{LT} \); b dawn: \( 6 \pm 3\,\text{LT} \); c noon \( 12 \pm 3\,\text{LT} \); d dusk \( 18 \pm 3\,\text{LT} \). Radar data in 2008–2017 at all operating frequencies were considered. The total number of available points n is shown at the bottom of each panel (yellow). In all panels, the solid lines are the lines of best linear fit
