Abstract

Vertical ionograms often contain traces of reflections that cannot be attributed to any type of the sporadic Es layer and are classified as anomalous reflections. Vertical sounding data at middle latitudes (Irkutsk) for 2012–2016 are used to study the morphological features of anomalous ionospheric reflections displayed in ionograms at virtual heights of 130–200 km. Characteristic daily, seasonal, and year-to-year variations are identified.
