Toolboxes for downloading and/or managing infrasound data exist across multiple computer languages:

• Python: ObsPy

• MATLAB: GISMO

• R: RSEIS

University of Alaska Fairbanks Geophysics Tools

  • Infrapy

    • Managers: Phil Blom, Fransiska Dannemann Dugick, Omar Marcillo, Jeremy Webster

    • Suite of tools that can be used to analyze seismic and acoustic array data at station and network levels (using beam-forming and clustering techniques, respectively) for the detection, association and location of events.

IMS_VASC

• Manager: Robin Matoza

• Combines infrasound signal association and source location using a brute-force, grid-search, cross-bearings approach

• Journal Article: Matoza et al. [2017]

CRes

• Manager: Leighton Watson
