Claim 8:
9. The air quality monitoring method of claim 1 further comprising:
receiving a reference spectra at predetermined concentration of each of water vapor, carbon dioxide and methane from a database;
applying transfer function of the first spectra signal as a convolution to the reference spectra of each of water vapor, carbon dioxide, and methane, to generate convoluted reference spectra;
generating synthetic spectra of each of water vapor, carbon dioxide and methane from the convoluted reference spectra for a plurality of concentrations at a measured temperature and a measured pressure; and
determining an actual concentration of each of water, carbon dioxide and methane, by minimizing difference of generated synthetic spectra and an actual spectrum from the first spectra signal.
