Fig. 3From: Inter-hemispheric imaging of the ionosphere with the upgraded IRI-Plas model during the space weather stormsObservations of the F2-layer critical frequency at source stations (left panel) and model reconstruction at the conjugate hemisphere (right panel) during the ionosphere-plasmasphere storm on 12–13 August, 2000, at solar maximum. The solid line indicates the median values, and the dashed line denotes the instant values.Back to article page
