A method for measuring a quantity of a gaseous species&#x2014;present in a gas and able to absorb light in an absorption spectral band&#x2014;comprises: arranging the gas between a light source and a measurement photodetector, the light source being suitable for emitting an incident light wave propagating through the gas to the measurement photodetector, which is suitable for detecting a light wave transmitted by the gas, in the absorption spectral band; illuminating the gas by the light source; measuring, by the measurement photodetector, a measurement intensity of the light wave transmitted by the gas, in the absorption spectral band; measuring, by a reference photodetector, a reference intensity of a reference light wave being emitted by the light source. The method comprises a correction of the reference intensity by consideration of a parametric model, the parameters of the model being determined according to reference intensity measurements performed at various times.
