Fig. 10From: Comparison of SuperDARN peak electron density estimates based on elevation angle measurements to ionosonde and incoherent scatter radar measurementsScatter plot of the F region peak electron density \( N_{\text{m}} F2 \) inferred from Rankin Inlet (RKN) radar measurements (beams 4–6) versus \( N_{\text{m}} F2 \) inferred from CADI measurements. All dusk sector observations in 2008–2017 were considered. The white line is the linear fit line to the data, as described in the textBack to article page
