2D modeling and basic processing with Madagascar

Download, Reformat, Smooth, and Display the Marmousi2 Velocity Model

We use the p-wave velocity field from the Marmousi2 model described by Irons (2005). Figure 1 shows the part of the model used in this paper. Figures 2 and 3 show the model smoothed for modeling and processing (NMO and migration).

These figures can be created with the command:

scons vp.view vpforward.view vpmigration.view

vp
Figure 1. A portion of Marmousi2 velocity used in this paper.

vpforward
Figure 2. The velocity smoothed for modeling.

vpmigration
Figure 3. The interval velocity smoothed for NMO and migration.
