Gas monitoring systems () and methods for determining a burning hydrocarbon effluent gas plume property. A laser emission system emits laser beams () along a path through the plume (). A detection system facilitates determining intensity data indicative of intensities of the laser beams () backscattered by a surface () after passing through the plume (). The laser emission system emits a first laser beam () along the path while tuning its wavelength around a wavelength corresponding to a COspectral absorption line. The laser emission system emits a second laser beam () along the path while tuning its wavelength around a wavelength corresponding to a spectral absorption line of a second predetermined gas. The processing system determines a first concentration path length of the CObased on the first intensity data, a second concentration path length of the second predetermined gas based on the second intensity data, and the plume property based on the determined concentration path lengths. The plume property may be the rate of emission of the second predetermined gas or the combustion efficiency.
