Spatial correlations of total electron content (TEC) variability are compared among two SAMI3 model runs and Jet Propulsion Laboratory Global Ionospheric Maps (JPL/GIM). Individual monthly correlation maps constructed with Equatorial reference points at 12 evenly spaced longitudes universal times. TEC composite (TCCs) then calculated by averaging the individual maps, shifted zonally to synchron...

Global Navigation Satellite System (GNSS) measurements of the Total Electron Content (TEC) from local (Dourbes, 50.1oN, 04.6oE) and European IGS (International GNSS Service) stations were used to obtain the TEC changes during the geomagnetic storms of the latest solar activity cycle. A common epoch analysis, with respect to geomagnetic storm intensity, season, and latitude, was performed on dat...

Modeling and forecasting of Total Electron Content (TEC) values by an Artificial Neural Network model (ANNm) have high agreement on November 2003, 2004 superstorms. The work discusses Solar Wind Parameters (SWp) from OMNI (Operating Missions as a Node the Internet) TEC (TECU) data (International Reference Ionosphere) IRI-2012, IRI-2016 20, 2003 (Dst = –422 nT) 08, –374 Geomagnetic Storms (GSs)....
