| Depth Coverage | 50-300 km |
| Area | eastern North America (latitude: 25.8°/°48.4; longitude: 273.4°/294.9°) |
| Data Set Description | The model file includes latitude, longitude, depth, and absolute S-wave velocity in eastern North America. The model was parameterized into a regular 0.35-degree horizontal grids in longitude and latitude directions. The vertical grid size increases with depth from one-third of the horizontal grid size for the top 15 km to ~5 km at 300 km depth. |
