Fig. 7From: 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 GSMaPNumber of data points in a 10° × 10° mesh used to obtain Figs. 6, 8 , 9 and 11. a No-rain at the satellite footprints at 120 km altitude along geomagnetic field in both hemispheres, i.e., at P1 and P2 in Fig. 1. b Weak rainfall (< 5 mm/h) at least one of the footprints but no heavy rainfall. c Heavy rainfall (> 5 mm/h) at least one of the footprints, P1 and/or P2. About 130 data points correspond to one satellite path. Note that the color scale for c is 10 times smaller than that for a and bBack to article page
