Vertical plasma density distribution (converted to plasma frequency) over Dourbes, as reconstructed by the LIEDR system (5-min resolution), during the eclipse day (A) and the control day (B). True-height contours for frequencies ranging from 2.8 MHz (bottom curve) up to 5.0 MHz (top curve) in steps of 0.2 MHz as obtained from Digisonde measurements at Dourbes during the eclipse day (C) and the control day (D). The shading indicates the eclipse time period, red arrows point at TID effects.
