Short summary
Many studies carried out for model validation are realised under geomagnetically quiet conditions. For climatological models this is not an issue. But for models like NeQuick, which plays a crucial role in daily human activities, it has to be evaluated under different conditions. Our study, which is probably a preliminary study, shows the advantage of the ingestion of ionospheric data. Thus, through this technique, a model could be assessed regardless of the geomagnetic activity.
