Fig. 9From: 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 GSMaPLongitudinally averaged amplitude of each component in a heavy rain cases (> 5 mm/h), and b in weak rain (< 5 mm/h). The GSMaP data at the footprints traced to 120 km altitude, i.e., P1 and P2 in Fig. 1, are used. The blank area within ± 10゜appears because the geomagnetic lines of force cannot reach satellite altitudes in this areaBack to article page
