The comparison of three types ionosonde data from Europe during an Interplanetary Coronal Mass Ejection (ICME) and a Stream Interaction Regions (SIRs) / Corotating (CIRs) -driven geomagnetic storm event is detailed in this study. selected events are 16-20 March 2015 for the ICME-driven 30 May to 04 June 2013 SIR/CIR-driven one. Ionospheric European stations, namely Pruhonice (PQ), Sopron (SO) Rome (RO), investigated. ionospheric F2-layer responses these analyzed with foF2 h’F2 parameter, calculated deltafoF2 deltahF2 values, ratio Total Electron Content (rTEC) Thermosphere, Ionosphere, Mesosphere, Energetics Dynamics (TIMED) satellite Global Ultraviolet Imager (GUVI) thermospheric [O]/[N2] measurement data. storm-time quiet day mean values also compared, it can be concluded that curves similar at all stations while ones showed latitudinal dependence development storm. As result electron density comparison, two SSC characterized ICME induced Travelling Atmospheric Disturbance (TAD) seen not storm, which stronger more prolonged negative effect probably due season.
