Fig. 2From: Polarization measurements of unusual cases of medium frequency burst emissions extending below 1.5 MHzSpectrograms of intensity (bottom panel) and polarization (top panel) of MFB emission observed at Toolik Lake on October 19, 2017, showing that the component of MFB below 1.5 MHz is left-polarized, like the bulk of the MFB emission, and unlike the right-polarized whistler mode auroral hiss emissionBack to article page
