All detections collected from Swarm A data have been assigned based on the inferred current strength using the SLC method at QD coordinate system. The detections are shown for both the Northern and Southern Hemispheres, with 95,462 in the Northern Hemisphere and 87,349 in the Southern Hemisphere. An approximate 90-minute interval is allocated each hemisphere for collecting each peak dataset, while each detection phase takes about 20 min to analyze data points above 50° QD latitude. Negative values represent westward electrojets, while positive values represent eastward electrojets.
