Dataset for "WUS256: An Adjoint Waveform Tomography Model of the Crust and Upper Mantle of the Western United States for Improved Waveform Simulations"

This dataset contains the WUS256 seismic model and auxiliary data used in the creation of the model (Rodgers et al., 2022).  WUS256 is a three-dimensional model of the seismic properties of crust and upper mantle of the western United States.  The WUS256 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).

Also included are the earthquake source parameters for the 72 inversion events and 18 validation events in ASCII text format.  Lastly, we include a list of all waveforms used in the creation of WUS256.  This is a simple ASCII file with the event name and receiver name (composed of the network_code and station_code).

This effort was support by Lawrence Livermore National Laboratory’s Laboratory Directed Research and Development project 20-ERD-008.  This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-MI-833624
