From: Measuring small-scale plasma irregularities in the high-latitude E- and F-regions simultaneously
Spectral properties binned by geomagnetic activity, in the nightside aurora. Panel (a) shows the small-scale spectral index, while panel (b) shows the total integrated power (rms), both binned by sme-index, and both showing the F-region density spectra in black circles and the E-region clustering spectra in red filled hexagrams, with errorbars denoting upper and lower quartile distributions. The rms in panel (b) is obtained by integrating psd over a similar frequency/wavenumber interval for both instruments. It is integrated between 1 and 25 km for Swarm A, and between 1.5 and 25 km for icebear 3D.
