Data Services Products: EMC-SPREM Smoothed Preliminary Reference Earth Models (SPREM)

Summary

SPREM_Vsv and SPREM_Vsh reference Earth models are based on the global reference model PREM with the discontinuities smoothed.

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).
