Some scripts for ambient noise tomography (support parallel computing and auto-correlation computation)

ANCC

Some scripts for ambient noise tomography, such as computing cross-correlation (with parallel computing), extracting dispersion curves.

1. convert the reftek file format (or other file formats) to the SAC file format (scripts)

   reftek2sac.py -> file convertor with the folder structure, such as /root/period_and_station_name/day/

   reftek2sac_p.py -> a parallel processing of reftek2sac.py

   reftek2sac2.py -> file converter with the folder structure, such as /root/period/station_name/day/

   reftek2sac2_p.py -> a parallel processing of reftek2sac2.py

2. cut daily data into predefined-segment data (scripts)

   This program first merges daily data, then cut it into predefined-segment. Simultaneously, it resamples data at each natural sampling point.

   cutdata.py -> cut daily data into predefined-segment data with the folder structure, such as /root/period_and_station_name/day/

   cutdata_p.py -> a parallel processing of cutdata.py

   cutdata2.py -> cut daily data into predefined-segment data with the folder structure, such as /root/period/station_name/day/

   cutdata2_p.py -> a parallel processing of cutdata2.py

3. cross-correlation and frequency-time analysis (Ambient Noise Denoise)

   It utilizes the AFTAN.

4. generating instrument response automatically (makePZfiles)

   In makePZfiles folder, you can generate automatically instrument response polezero files using resp2pz.py or makePZs.py once fill a excel sheet based on your project log. The former can take responses of sensor and DAS into consideration, it will merge them into one PZ file. While, the latter only take the response of sensor into consideration, then genertes corresponding PZ files automatically.

Prerequisite

The SAC software is required by the AND.
The obspy is required by the scripts.
