Differential Optical Absorption Spectroscopy, or DOAS, is a widely used method to determine concentrations of atmospheric species. The technique was first used by U. Platt and D Perner in the late 70s, [6]. It has been used for groundbased applications as well as satellite measurements, for both active and passive instruments [5]. In general, the DOAS technique, is about analysing broadband spectra, in the UV and visible region, that has been transmitted through a long open path. Different atmospheric species will leave their absorption fingerprints in the spectra from which concentrations could be retrieved.
