Paper Abstract

We present estimates of influence of refraction on gas throws concentration measure by trace gas analyzer. The used model of spatial distribution of gas concentrations is correspond to gas throws from pipe lines. The molecules of CH4 were considered as markers of such gas throw. Influence of refraction on parameters of collimated probing beam was shown to result mainly to its shift relatively receiver telescope.
