On the horizontal distribution of high-latitude plasma density irregularities under particle precipitation
We present small-scale plasma density irregularities simultaneously observed by L-band Synthetic Aperture Radar (SAR) and European Incoherent Scatter (EISCAT) radar in Tromsø, Norway. The irregular electron density is characterized by tens of kilometers of band-like structures aligned in the east–we...

We present small-scale plasma density irregularities simultaneously observed by L-band Synthetic Aperture Radar (SAR) and European Incoherent Scatter (EISCAT) radar in Tromsø, Norway. The irregular electron density is characterized by tens of kilometers of band-like structures aligned in the east–west direction with small patch-like structures. We estimate the local change of total electron content (TEC) and the height of ionospheric irregularities. This event occurred under high levels of ionization of up to approximately 300 km in height triggered by nighttime particle precipitation. The observed structures are likely to be caused by precipitating electrons and may have been cascaded into smaller scales.
