Intended Scope - uofuseismo/anxcor GitHub Wiki
For creating velocity models with seismic ambient noise, the following is a typical workflow:
- Download/get data
- remove instrument response
- Time Synchronize
- Remove Mean/Trend, Lowpass to 1/2 nyquist, resample
- Cut into windows
- Custom Processing routines, possibly spectral whitening and/or temporal normalization
- Cross-correlation
- Stack cross-correlations
- Rotate stacked correlations to azimuth/back azimuths
- Perform Frequency-time analysis to get group and phase velocities
- Do your science (ex: inversion).
Anxcor's current scope expects the user to do 1-3, although we have some examples of how to do these in the tutorial. 10 & 11 are for the moment left for the user to do, but we might implement 10 in the near future.
