Abstract

A system for detecting gas leaks and determining their location and size. A data gathering portion of the system utilizes a hub and spoke configuration to collect path-integrated spectroscopic data over multiple open paths around an area. A processing portion of the system applies a high-resolution transport model together with meteorological data of the area to generate an influence function of possible leak locations on gas detector measurement paths, and applies an inversion model to the influence function and the spectroscopic data to generate gas source size and location.
