Determining ULF Wave Contributions to Geomagnetically Induced Currents: The Important Role of Sampling Rate

Abstract Past studies found that large‐amplitude geomagnetically induced current (GIC) related to magnetospheric Ultra Low Frequency (ULF) waves tend to be associated with periods >120 s at magnetic latitudes >60°, with comparatively (a) smaller GIC amplitudes at lower latitudes and shorter wa...
