Fig. 8From: Global distribution of magnetic ripples and electron density fluctuations as observed by the Swarm satellites on the dayside and their relation to the rainfall estimated by the GSMaPSame as Fig. 6a and b, but in Apex coordinate system. The blank area within ± 10º Apex latitudes appears because the geomagnetic lines of force in this area cannot reach satellite altitudes. The Apex latitudes of the coast-lines are calculated at 120 km altitudes assuming that the magnetic ripples are generated in the ionospheric dynamo layerBack to article page
