  "Description": "Developed for use by those tasked with the routine\ndetection, characterisation and quantification of discrete\nchanges in air quality time-series, such as identifying the\nimpacts of air quality policy interventions. The main functions\nuse signal isolation then break-point/segment (BP/S) methods\nbased on 'strucchange' and 'segmented' methods to detect and\nquantify change events (Ropkins & Tate, 2021,\n<doi:10.1016/j.scitotenv.2020.142374>; Ropkins et al., 2026,\n<doi:10.21105/joss.08839>).",
