Overview

CVM-H - CVM-S map plot of Vs at depth 0m.
CVM-H map plot of Vs at depth 0m.
CVM-S map model of Vs at depth 0m.

The plots at right show a difference map of CVM-H - CVM-S, followed by a plot of CVM-H, and CVM-S. Note that these plots are using different color scales because the velocities in the two models are quite different. Also, CVM-H contains an extensive near-surface GTL while CVM-S has a very limited GTL.

3D meshes of a large southern California region have been extracted at 2km resolution into netCDF format in the "CF" convention:

These meshes may be viewed in IDV (See the IDV Tutorial). The difference plot uses a custom color table which may be downloaded from Velocity Difference Color Table and imported into IDV.
