The dataset consists of synthetic seismograms recorded using the SPECFEM3D wave propagation software. Data from 8 isotropic earthquake sources were recorded at 630 stations while data from 8 realistic earthquakes were recorded at 520.

The dataset is consisted of travel-time records in SEG2 format recorded using multi-station arrays near 6 seismographic stations located in southern California. A table in the spreadsheet (vs30data.SCE.FINAL01.xlsx) summarizes the data collection. Included in the dataset are figures showing incremental results supporting the resultant modeled shear-wave velocity (Vs) profile and estimated time-averaged Vs in the upper 30 m of the subsurface (Vs30). Incremental results include plots of the picks of fundamental mode dispersion curve, the modeled Vs profile and estimated Vs30, and the empirical and theoretical dispersion curves.

Synthetic seismograms provide a means to calibrate (groundtruth) seismic-reflection profiles to specific subsurface stratigraphic features observed in one-dimensional core and geophysical log data acquired from wells. Independently, Walker Marine Geophysical Company and Geokinetics Incorporated used velocity data from 14 borehole-compensated sonic logs as input for specialized geophysical software to generate 14 synthetic seismograms. Velocity data from the sonic logs were converted to a synthetic seismic trace using synthetic-seismogram production software, reproduced either 5 or 8 times, and placed side-by-side to resemble a seismic-reflection profile. For each well, the synthetic seismogram was used to relate geologic and geophysical well data to the respective seismic-reflection data. Stratigraphic and hydrogeologic interfaces were fit to the true wavelet traces on seismic-reflection profiles. Selected stratigraphic and hydrogeologic interfaces were identified on the basis of comparisons to published geologic and hydrogeologic frameworks. The direct correlation of key traces on the synthetic seismograms to seismic-reflection profiles was not a perfect fit; however, some disparity is common between synthetic seismograms and seismic-reflection profiles (Bruns and others, 1994) and in many cases is a result of imperfect modeling of synthetic seismograms.
