Model Download US_CrustVs_SLK_GRL_2015.txt — model as Latitude, Longitude, Depth, Vs (km/s). The model was pre-gridded on a regular 0.2 degree horizontal grid, with vertical layers every 1 km from 0-60 km and every 20 km from 60 to 120 km.
The above model in netCDF and GeoCSV formats:
US-CrustVs-2015_kmps.nc (see metadata ), is the netCDF file for the model

US_Crust_GRL_2015_CrustThickness.txt — the crust thickness map as Latitude, Longitude, thickness (km) with values rounded to the nearest 1 km for the Vs model.

Vs tomography and crustal thickness maps of the U.S.
[Schmandt et al., 2015] Vs tomography and crustal thickness maps of the U.S. A) Upper crustal Vs, mean from 0-11 km depth. B) Middle crustal Vs, defined as the upper half of the interval between 11 km and the local Moho depth. C) Lower crustal Vs, defined as the lower half of the interval between 11 km depth and the local Moho. D) Uppermost mantle Vs at 60 km depth. E) Crustal thickness.
