Estimation of Seismic Attenuation of the Greenland Ice Sheet Using 3‐D Waveform Modeling

We estimated the seismic attenuation (Q factor) of the Greenland Ice Sheet (GrIS) by comparing observed and theoretical Rayleigh waveforms. Observed waveforms are obtained by interfering noise waveforms in vertical‐component seismograms between stations belonging to the latest broadband seismic netw...
