Fig. 1From: Ionospheric irregularities and scintillations: a direct comparison of in situ density observations with ground-based L-band receiversExamples of \(N_e\) variations for Swarm A, B, and C passes near Mbarara longitude of about \(\mathrm 30.8^{\circ }\). The dashed gray vertical line represents the quasi-dipole latitude of Mbarara GPS-SCINDA (\(\approx \text{-10.1 }^{\circ }\)). The dashed blue horizontal line in panel (b) represents the threshold applied for the detection of ionospheric irregularitiesBack to article page
