Two-dimensional imaging of plasma density structures in auroral ionosphere
We present multi-instrumental observation of auroral ionosphere by using the EISCAT UHF radar, all sky imager, GNSS satellites and Synthetic Aperture Radar (SAR) satellite. Plasma irregularities generated by auroral precipitating particles are imaged by SAR phase data in high resolution (less than k...

The observed localized density irregularities are aligned in east-west direction near the location of 558-nm optical emission. The results suggest that highly structured plasma density gradients exist primarily near the edge of the precipitation region.
