Interpolation of externally-caused magnetic fields over large sparse arrays using Spherical Elementary Current Systems

A physically-based technique for interpolating external magnetic field disturbances across large spatial areas can be achieved with the Spherical Elementary Current System (SECS) method using data from ground-based magnetic observatories. The SECS method represents complex electrical current syst...
