Abstract
This chapter describes how the Spherical Elementary Current Systems (SECS) are applied to analyze the magnetic and electric field measurements provided by the Swarm spacecraft. The Swarm/SECS method produces two-dimensional (latitude–longitude) maps of the ionospheric horizontal and field-aligned currents around the satellite paths. If also electric field data are available, similar maps of the electric field and conductances can be obtained.
