## Smoothing the 1-D velocity model of Dobra Voda for ray tracing

**Petr Bulant**
### Summary

The algorithm of constructing smooth velocity models suitable for ray tracing
by inversion of given data with minimization of the Sobolev norm
composed of the second derivatives of velocity
is applied to the 1-D P-wave velocity model of the Dobra Voda locality.
The data available for the Dobra Voda locality are strongly heterogeneous,
and the
application of the smoothing algorithm to the 1-D model
requires proper selection
of the amount of smoothing and appropriate parameterization of the model.
Numerical tests performed for individual vertical profiles indicate
that the data do not allow
to apply the smoothing algorithm with uniform smoothing
to the 3-D velocity model of the locality.
