- Adjoint simulation with source signal as Ricker wavelet applying at station locations
Test: Input the Ricker wavelet/ Time-derivative of Ricker wavelet as a body force at a random station from files with similar format to the recorded seismograms. The adjoint emod3d simulation should perform similarly to the forward emod3d with the only difference: the source using was multi-channel source applied simultaneously at all receiver locations.
Pass criterion: The recorded seismograms at stations should be similar to the combination of seismograms from multi forward simulations with a single source location at each station. The seismograms can be examine in term of time series (magnitude and phase) and frequency contents.
Note: For visual examination of the adjoint simulation, we can apply the active source at one station and record the seismograms at the other stations. - Calculation of adjoint source for P-arrival components for each seismograms using GSDF method
