Coincident multi-point observations of the E- and F-region decametre-scale plasma waves at high latitudes

► The E-region backscatter observed by the PolarDARN radars is presented. ► Most echoes are detected at locations where geometric magnetic aspect angles are in excess of 10°. ► The spectral echo types are very similar to that detected by the auroral SuperDARN radars. ► A new radar setup that has coverage of the E and F regions on the same magnetic field lines is used. ► The E-region phase velocity dependence on the electric field strength and the flow angle is studied.
