hmF2 prediction combining both models (red line bottom panel). Red points correspond to experimental values for the corresponding geomagnetic storm. Black points correspond to averaged representative profile data. Black line corresponds to quiet-time hmF2 prediction using the SHA model. Gray dashed line corresponds to IRI-2007 prediction. White sun indicates the sunrise and black sun the sunset. IMF Bz and Dst index are indicated. Vertical gray dashed line indicates the triggering time.
