Claim:
1. A method for estimating a distance to a source of a gas leak from an estimate of a width w of a gas plume from the gas leak, the method comprising: performing multiple gas concentration measurements at two or more separated measurement points, wherein each data point of the gas concentration measurements is a simultaneous concentration measurement at the measurement points; providing a time-independent gas plume model having at least plume spatial width w as a fitting parameter, wherein the gas plume model also includes parameters for plume position; fitting the gas plume model to the data points, wherein the plume position is allowed to be a random variable to enable fitting to observed scatter in the data points, to obtain an estimate w* of the plume spatial width w; and providing as an output an estimate of a distance X* between the measurement points and a source of the gas plume from the estimate of the plume spatial width w*.
