Figure 3From: Polarization analysis of VLF/ELF waves observed at subauroral latitudes during the VLF-CHAIN campaign Polarization parameters and PSD for chorus band emission starting at 18:30 UT on 18 February. Thirty-minute plot of polarization parameters (a-c) and power spectrum density (d) of a chorus band emission (f = 3 kHz) observed at ATH on 18 February 2012 from 18:30 to 19:00 UT. Blue and red arrows indicate the half-gyrofrequency calculated at the magnetospheric equatorial plane of the L-shell of ATH, using T96 and T01 models, respectively.Back to article page
