英文摘要	The invention relates to the field of systems for providing safety during the transportation and storage of a gas and concerns a method for remote measurement of a concentration of gas in the atmosphere. The measurements are carried out with the aid of a gas analyzer which is mounted on an aerial vehicle and comprises a controllable diode laser, an analytical channel and a reference channel. The processing of measurement signals and reference signals comprises defining a cross-correlation function, defining an auto-correlation function of the reference channel and filtering noise from the analytical channel using the functions produced. Furthermore, a coefficient of cross-correlation is defined depending on the values of the functions produced and a concentration of gas in the analytical channel is defined depending on the coefficient of cross-correlation. Simultaneous detection along different lines of absorption is then carried out, allowing a wide dynamic range of gas concentrations to be measured in the surface layer of the atmosphere.
