Interhemispheric comparison of the ionosphere and plasmasphere total electron content using GPS, radio occultation and ionosonde observations

We present a comparison of the ionosphere and plasmasphere total electron content over nearly geomagnetic conjugate locations Pruhonice (50.0°N, 14.6°E; 45.7°N geomagnetic), Czech Republic and Hermanus (34.4°S, 19.2°E; 42.3°S geomagnetic), South Africa during the low solar activity period of 2009–2010. The bottomside ionosphere, topside ionosphere and plasmaspheric contributions to the total electron content (TEC) derived from the Global...
