Short summary
Effect of background gas composition on the spectroscopic measurement of CO2 concentration at ambient levels has been investigated. The wavelength-scanned cavity ring-down spectroscopy was employed to explore the spectral line shape of CO2 at 1603 nm. It is revealed that the instrument response should be corrected with respect to a total pressure broadening coefficient given by a matrix composition. The correction method is validated by high accurate gravimetric standard gas mixture.
