Observed and synthetic seismic waveforms used to constrain anelastic attenuation (Q factor) of Greenland Ice Sheet
These data are observed and synthetic RAW waveforms used to constrain seismic anelastic attenuation (Q factor) of the Greenland Ice Sheet (Toyokuni, Komatsu, & Takenaka, 2021, JGR). ### Observed waveforms ### ./OBS: Folder containing observed waveforms ./OBS/years_(station1)_(station2).dat: A 4....
