Waveform inversion code

This section presents program code for seismic full waveform inversion. Efficient implementations of the adjoint inversion approach are provided as well as code for the calculation of full waveform kernels in 3D. Further, global search algorithms are provided for application settings with small parameter space (i.e. for 1D structures).

Title Short Description

FW-NA is a package of Fortran programs based on a Monte Carlo approach for solving a waveform inversion and thus defining the 1-D physical properties of small-scale structures. 

IFOS is a 2D elastic full waveform inversion code.

It is a highly modularized program suite for sensitivity analysis and iterative full waveform inversion using waveform sensitivity kernels for 1D or 3D heterogeneous elastic background media and makes use of different forward modelling codes.
