Theory of multiwave differential optical absorption spectroscopy surface ozone measurement with open path meters
The multiwave differential optical absorption spectroscopy (DOAS) technique is normally applied to obtain information on a few gas components in a mixture, as well as to reduce errors while evaluating their concentrations. Multiwave measurements also lead to a universal concept for analysing possible sources of errors affecting the accuracy of gas concentrations. This method allows precise estimation of the contribution of every error source to measurement results. A mathematical formulation of multiwave technique for measuring surface ozone concentration with a DOAS open path instrument is presented here along with an analysis of the role of spectral differences in the sounding radiation emitted to sondage and auxiliary routes.
