Fig. 4From: Comparison of SuperDARN peak electron density estimates based on elevation angle measurements to ionosonde and incoherent scatter radar measurementsA contour plot of the F region peak electron density versus local time a for the Rankin Inlet (RKN) radar measurements in beams 2–6 and gates 15–40 and b according to CADI measurements at Resolute Bay. Solar local time was counted for the radar location, LT = UT − 6.5. Data at all RKN radar operating frequencies were consideredBack to article page
