ipensive (Version 1.0.0)

July 15, 2026

ipensive is a tool for processing infrasound array data. It was developed for volcano monitoring for operational use at the Alaska Volcano Observatory and has been slightly generalized for broader use. The code processes infrasound and hydroacoustic array data in 10-minute increments, generating images and a webpage for displaying/navigating those images. Much of the package is a wrapper around Jordan Bishop's least trimmed squares package (https://uaf-lts-array.readthedocs.io/en/master/index.html#), which performs the calculations to estimate trace velocity, back-azimuth, cross-correlation maxima, and flagged array element pairs (details: https://doi.org/10.1093/gji/ggaa110)
