Fig. 3

a and b present in gray the number of Swarm orbits with available electric field data between 1800 and 0600 magnetic local time (MLT) from 10 January 2013 to 4 November 2021. In green are the number of equatorial plasma depletions (EPDs) used in this study. In a, the counts are organized by months with pixel dimensions of 10 days per 30 min. b shows the counts as a function of geographic longitude with pixel dimensions of 10\(^{\circ }\) per 30 min. Histograms in gray and green on the top and on the right of the plots are for reference purposes
