jgrb50143-sup-0001-Supplemenray FiguresRS.pdfPDF document57KThis material includes filtered records at four regional stations for the time interval of 5400 s (90 min) to show the arrival of coherent low-frequency signals in the respective time intervals. More detailed figures are shown in Figures 3a and 3b.
jgrb50143-sup-0002-SupplementaryFiguresGS.pdfPDF document120KThis material includes filtered records at eight global IMS stations for the time interval of 5400 s (90 min) to show the arrival of coherent low-frequency signals in the respective time intervals. More detailed figures are shown in Figures 4a–4h.
jgrb50143-sup-0003-Auxially Material2.pdfPDF document955KArnold Research and Development Center (ARDC) standard atmosphere and its approximation by isothermal layers (taken from [Harkrider, 1964, Figure 1]). (a) Phase and group velocities dispersion curves for S0,1,2 and GR0,1 modes of ARDC standard atmosphere with half-space beginning at 220 km. Stippled region indicates where the singular value of F occurs, whereas hatched region indicates cutoffs (taken from [Harkrider, 1964, Figure 5]). (b) Same as Figure 2 but with different scales (taken from [Harkrider, 1964, Figure 6]). Spectral amplitude of AA(ω) for the ARDC standard and Arctic winter atmospheres. Spectral amplitude of the barograph is superimposed (taken from [Harkrider, 1964, Figure 7]).
