Auroral streamers in low-elevation northward-looking EISCAT VHF data. Streamers start from the vicinity of the polar cap boundary (solid continuous near-horizontal line) and propagate equatorward. Panels from top to bottom: beam-aligned ion velocity, T e, N e, and T i (Pitkänen et al. 2011). Volumetric multi-static observations are needed to resolve the widths and orientations of the N e structures as well as associated plasma flows
