Datenpaket: Workflow for multi-array beamforming in seismology to detect ocean microseism

The code and data in this repository is linked to the research article:

"High-Resolution Spatiotemporal Monitoring of Secondary Microseisms via Multi-Array Analysis, Gao, Y., Rietbrock, A., Tilmann, F., Dushi, E., Geophysical Journal International (2025, under revision)

This data repository contains the following files and subdirectories:

Beamforming:

Hinet:
Slowness_data_hourly:
beampower data and backprojection distance_baz_slowness_:
distance and back azimuth from the global grid to the center of network assuming seismic phase, e.g. P or PKP

Summary_dailyplot_hourly_withwwiii3.py: plot the multi-array beamforming and
compare with significant waveheight, surface spectral density, and P wave equivalent force on the ocean floor

CCF:
Is an empty dir but should store the cross-correlation data in ASDF format,
due to the large size of dataset, the data could be obtained on request.
