Summary
HMSL-P06, Houser et al. (2008) , is an isotropic P velocity model with 18 layers (approximately 100 km thickness in the upper mantle and 200 km in the lower mantle) and 2578 blocks in each layer (approximately 4 degree equal area blocks at the equator).

| Short Description | HMSL-P06 is an isotropic P velocity model with 18 layers (approximately 100 km thickness in the upper mantle and 200 km in the lower mantle) and 2578 blocks in each layer (approximately 4 degree equal area blocks at the equator). The upper mantle is constrained to be a scaled version of HMSL-S06 using the ratio dlnVs=1.7*dlnVp since we do not use upper mantle P phases. The lower mantle is constrained by long period P, PP, and PP-P travel times. Corrections are made for CRUST2.0 and ellipticity. While ak135 is the 1D model used for ray tracing in the inversion, the travel time measurements for each phase have the mean removed, so the 3D model is not built with respect to any particular 1D model. | |
