Abstract Three new methods for estimating a ratio of the ultra-low frequency (ULF; 1–100 mHz) wave equatorial electric field amplitude in the Earth’s magnetosphere to ground magnetic field amplitudes for field line resonances are described. These methods use ratios of the time series extrema, ratios of the envelope waveform and the ratio of the spectral amplitude at the field line resonance frequency. These methods were applied to four ULF resonance intervals; three detected by the Van Allen Probe A spacecraft and one de ...

The power spectrum of the compressional component of magnetic fields observed by the Van Allen Probes spacecraft near the magnetospheric equator in the dayside plasmasphere sometimes exhibits regularly spaced multiple peaks at frequencies below 50 mHz. We show by detailed analysis of events observed on two separate days in early 2014 that the frequencies change smoothly with the radial distance of the spacecraft and appear at or very near the frequencies of the odd harmonics of mutiharmonic toroidal mode standing Alfv\ en wa ...
