Abstract. We study the quantification of signal strength in wavelength-modulation spectroscopy, and present algorithms which allow for the quantitative analysis of second-harmonic spectra for arbitrary combinations of line width and modulation depth. The algorithms are validated through measurements on CO lines in the 0 ? 3 overtone band. They can be used for measuring the line strength of lines that are too weak to allow direct absorbance measurements, and for quantifying the response from monitors applying wavelength-modulation under conditions where calibration with certified gases is not feasible.
