Description
| Name | SPREM (SPREM_Vsv & SPREM_Vsh) |
| Title | Smoothed Preliminary Reference Earth Models (SPREM) |
| Type | 1-D Reference Earth Model |
| Sub Type | Vs |
| Year | 2016 |
| Short Description | SPREM_Vsv and SPREM_Vsh reference Earth models are based on the global reference model PREM with the discontinuities smoothed. For each propagation path analyzed the crust of SPREM_Vsv or SPREM_Vsh is replaced by the path averaged crust taken from LITHO1.0 (Pasyanos et al., 2014). |
