Dataset and Model Files for Full Waveform Inversion Seismic Earth Model WUS324

Dataset and Model Files for Full Waveform Inversion Seismic Earth Model WUS324 Arthur Rodgers Geophysical Monitoring Program, Lawrence Livermore National Laboratory, Livermore CA 94551, USA; and Department of Earth Sciences, Eidgenössische Technische Hochschule Zürich, Zürich, Switzerland [e-mail] 10.5281/zenodo.11619519 Summary This data set includes the metadata and model for the three-dimensional (3D) seismic Earth model WUS324 (Rodgers et al., 2024). This model describes seismic wavespeeds, density and attenuation for the 3D volume spanning the surface to 400 km depth, latitudes from Mexico to Canada (28 to 52) and longitudes from the Pacific Ocean to the Great Plains (-132 to -100). The metadata tabulates the earthquakes and seismic networks and stations used in the creation and validation of 3D seismic Earth model WUS324. The WUS324 model is provided in NetCDF format (readable by for example, xarray, Hoyer & Hamman, 2017) and HDF5 format for viewing with ParaView (Ahrens et al., 2005) and interaction with Salvus (Afanasiev et al., 2019).
