Map of the EMMA stations (square markers) used for the plasmasphere analysis. Green squares identify the station pairs used to describe in detail the plasmasphere dynamics at three different latitudes. Red circles are the positions of the global navigation satellite system receivers nearest to the considered station pairs and used for the ionospheric analysis described in “Ionospheric response in terms of vertical, top, and bottom TEC.” Coordinates are geographic. See Table 1 for additional info about the EMMA stations used in the analysis
