I. U. Observatorio del Ebro, Universitat Ramon Llull Center for Atmospheric Research, University of Massachusets Lowell Concluding Remarks ► The results presented suggest that the main driver of this ionospheric response is neutral wind and composition change bulge supporting the storm development model suggested by Prölss, [1993]. ► In our study we were able to reconstruct the local time dependence of the storm effects ► Other storms effects do not manifest themselves systematically (GW, + or - f 0 F2 effect, shock effects, … ). ► IRI model does not reproduce the observed uplifting of the ionosphere during the storm time. ► Digisonde worldwide network offers an excellent tool for studying spatial effects of the magnetic storms. It provides an advantage of looking into the altitude distribution of the ionospheric reaction. IRI/COST 296 WORKSHOP; July 2007, Prague, Czech Republic 17
