Claim:
1. A method comprising employing at least one processor to: identify a first gas emission plume event according to a first set of gas emission data resulting from a first mobile measurement run performed by a mobile measurement device along a first measurement path, the first set of gas emission data reflecting a first set of gas concentration data acquired during the first mobile measurement run and a first set of associated atmospheric condition data characterizing the first mobile measurement run; generate a prior 2-D surface map of gas emission source probabilities according to the first set of gas emission data; receive a second set of gas emission data resulting from a second mobile measurement run, the second set of gas emission data reflecting a second set of gas concentration data acquired during the second mobile measurement run; and update the prior 2-D surface map to generate a posterior 2-D surface map of gas emission source probabilities according to the second set of gas emission data, wherein generating the posterior 2-D surface map comprises determining an updated probability of a gas emission source being present at a given location according to a product of a prior probability of the gas emission source being present at the given location and a probability of observing the second set of gas emission data given the gas emission source being present at the given location.
