1. A method comprising:

  • performing a sequence of gas leak detection survey runs along a common survey path, each gas leak detection survey run comprising measuring gas concentration values using at least one gas concentration measurement device carried by at least one moving vehicle along the survey path;

    employing at least one hardware processor to generate a sequence of emission rate indicators indicative of an emission rate of a gas emission source measured at a geospatially-referenced location over multiple gas leak detection survey runs, each emission rate indicator being determined according to a concentration of a gas measured during a corresponding gas leak detection survey run; and

    employing the at least one hardware processor to determine that a change in the emission rate of the gas emission source meeting a predetermined condition has occurred by performing a comparison between a first subsequence of the sequence of emission rate indicators and a second subsequence of the sequence of emission rate indicators.
