Abstract
Flux estimates for gas plumes from gas leaks are obtained from a 1-D horizontal line scan of gas concentration measurements, combined with an estimate of the vertical extent of the gas plume. In this manner, flux estimates for gas plumes can be obtained without having to gather a 2-D image of gas concentration data.
